GIBBER FACTOR*

out of five.



Overview
Tower Ridge - the ultimate British scramble! Tower Ridge is to scrambling what The Isle of Man TT is to motorcycling, it just doesn't get any better.

OK some scrambles are longer, some are steeper, some are technically harder - but Tower Ridge takes the best combination of all that makes scrambling fun and puts it all together in a single ridge to the summit of Britain's highest montain.

Once you have Tower Ridge safely ticked off in your log book you also know that you can cope with pretty much anything that scrambling routes can throw at you - you've just made the transition from scrambler to mountaineer

Note Tower Ridge is at the very edge of what is considered to be a scramble. Some guidebooks grade it as a Diff rock climb and in winter it merits a grade III rating for its length and exposure. It's not a route for the inexperienced scrambler, best to cut your teeth elsewhere.

Bear in mind that in winter conditions, Tower Ridge is a serious, graded winter climb with a reputation for forced benightments so leave well alone unless you're an experienced winter mountaineer. Something like Ledge Route is a better starter ridge / buttress route.


Approach From the car park near Torlundy follow the signposted path to join the Allt a' Mhuillinn. Keep the stream to your left and ascend into the obvious bowl of Corrie Leis to the Charles Inglis Clark (CIC) Hut. The hut is almost directly below the base of Tower Ridge.
Route
Identifying the ridge is no problem, with the impressive Douglas Boulder obvious instantly - this "boulder" is a 300m high lump of rock that provides an alternative, climbing grade, start.

Pic John Cameron from OM Gallery

Once you've identified the boulder, move east around its base to the bottom of Observatory Gully. Once the angle of the rock on the right eases scramble up into the start of Eastern Gully and a grassy bay.

From here ascend the scree to the obvious Douglas Gap above. A 20m leftwards slanting chimney leads up to the crest of the ridge on good holds, though the rock is a bit polished. Exit the chimney to the left onto the main ridge and easier ground.

The ridge steepens again, and heads towards a section of overhanging rock. Move right here onto a ledge and a scramble back up to the crest of the ridge. The next obstacle is The Little Tower, which is more of a significant steepening than an actual "tower". The best route here takes the left hand edge, with big drops below, onto a narrow ledge. From a small platform move back slightly right and climb up good holds to regain the ridge above the Little Tower.

Easy ground now leads to the base of The Great Tower. This is as much a "crux" as the fabled Tower Gap further on, but it also marks the point of no return. Climb the first two steep sections to gain the Eastern Traverse on the left. This traverses round the edge of the Great Tower to a large block which ends the traverse.

Escape Route At this point you can go left where a large boulder lies close to the main cliff to access a scree ledge into the upper part of Eastern Gully, and a scree climb to the summit plateau.

To continue the ascent of the ridge go through the gap between the boulder and the main face and emerge onto steep, exposed, ground (rope advisable) leading back up onto the ridge above The Great Tower.

The next section demands a head for hights and fast but safe movement. With frightening drops to either side the traverse of the ridge to Tower Gap is as exposed a spot as you're likely to find, and particularly dangerous in high winds. Continue along the ridge to Tower Gap, where things have got easier recently as a block has detatched from the wall and fallen directly into the gap.

Again a rope is advisable here, as you lower yourself from a projecting block into the gap. Cross the small gap to the far wall, and climb a series of small cracks and holds on the left. The ridge steepens one more time ahead, but a path leads left to right to a ledge and short groove. This leads to the summit plateau and end of a scramble that will live in your mind for ever.

The summit of Ben Nevis lies off to the left , where you can join the "normal" route back down the mountain.


Caution Scrambling is potentially dangerous and, particularly at the higher grades, requires technical skills and equipment to minimise the risk. We suggest that you take professional instruction or climb with an experienced partner.

Just seen the tower ridge 'scramble' in your weekly routes, I agree with what you say that TR is one of the best climbs in Britain, having only ever done it in winter so I cannot comment on the grade in summer. However my guidebooks give it diff, I think In the past I have seen it graded V diff. Can you please clarify what is currently the boundary between scrambling & climbing, lest in a couple of years we may all be doing scrambles with 5b & 5c, maybe even 6a pitch's on them. (english that is)
Posted: 28/11/2005 21:09

Kit,
Grading scrambles is a nightmare. One man's grade 4 is another man's grade 2 - and both grades are a climber's stroll. Wherever possible I go with the conventional grading given to scrambles that have previously been published.

Tower Ridge is universally graded as a Scottish grade 5 (English and Welsh only grade from 1 to 3) in all the publications I've seen.

As for where the boundary is between scrambling and rock climbing - that's almost impossible to given an objective answer that applies to everyone. The tradition crossover point lies around the diff/v diff climbing grade - but climbing grades tend to lower over time, while the standard of scrambles rarely changes. To many a scramble becomes a climb where the majority of the route has to be undertaken roped and using protection. In some ways I find it easier to think of a route that marks the limit of scrambling rather than a figure - and to me personally Tower Ridge is that limit. As I said in the description, this marks the transition from scrambler to mountaineer.

Obviously this answer can't be definitive to scrambling as a whole, but I hope it helps you understand how I give the routes on here their grades

Dave :)

Dave,
I think you are on dodgy ground here diffs are rock climbs, they are well documented in all area's by the national governing bodies guidebooks, why change the status.

Tower ridge is universally graded as a diff rock climb and has been included in SMC journals since it was first ascended in 1892.

You say grading scrambles is a nightmare,the reason you are having problems is because are trying to merge scrambles with climbs.

What you are doing is introducing another grading system, if the grades keep creeping up you will end up like the australian system where 19 is approx HVS, 20 E1, 25 is E5.

In this country we already have our own traditional system E6 7a, french sport grades 7a,7b,7c etc.
Then we have bouldering grades-font 7a, 7b, 7c etc.
Ice climbing grades, and dry ice tooling grades.
Now you you are introducing the australian system.

You are adding unnecessary confusion to an already complex issue.

Fast forward to OM 12/05/2015

Did a fantastic (myford)grade 25 scramble on gogarth main cliff last weekend called Positron, best pitch in Wales.

cor, proverbial can of worms time
Posted: 29/11/2005 09:26

Classic Rock has it as a 2000ft Diff. Looking at the pictures in C.R., I wouldn't say it's a scramble. However, Dave is using Scottish scramble grades, whereas English ones only go up to 3s. Not sure if that makes it different or not?
Posted: 29/11/2005 09:29

will chip in later when I'm home and can confirm my facts before posting incorrectly.

But Cara I will say, what some people used to call climbs are now days considered scrambles. So because it is in classic rock just means it was considered a climb then. I'm not saying it is or isn't at the moment, until I get home as I said and confirm a few things before posting.
Posted: 29/11/2005 09:33

Kit,
"What you are doing is introducing another grading system" - Sorry but you're wrong! Let me quote from Andrew Dempster's Classic Mountain Scrambles In Scotland - "Grade 5: Extremely serious, highly commiting and demanding scrambles consisting mainly of Moderate rock climbing, but with some pitches of a Difficult standard. For highly experienced scramblers only, and preferably those who have some rock climbing experience. A rop0e is highly recommended - even if not used:eg Tower Ridge (Ben Nevis); Main Cuillin Ridge Traverse (Skye). That was written in 1992, so the definition is neither mine nor new!

If you were to remove all graded scrambles that include a section of graded rock climbing there would be hardly any scrambles left. Routes like Clogwyn Y Person Arete include sections graded at Mod - Diff.

Posted: 29/11/2005 10:25

As I'm only familiar with the English/Welsh scramble grades can you clarify one point for me ? Is a Scottish grade 3 the same as an English/Welsh grade 3 ? In other words are Scottish 4s and 5s extar difficulty levels or is the grading in scotland just divided into finer increments ?
Posted: 29/11/2005 11:35

Bill, in my opinion English/Welsh Grade 3S is roughly equal to Scottish Grade 4, with Grade 5 slightly higher.
Posted: 29/11/2005 11:53

I always thought it was quite normal for the upper end of scrambling grades to overlap with climbing grades. I haven't got guide books handy here but I'm sure there are things on Idwal Slabs (for example) that are graded as 3S in the scrambling guide and as mods in the CC climbing guide. I thought is was commonly accepted that 3S (or even 3) overlaps with 'mod'?
Posted: 29/11/2005 11:57

WD, yes, you're right. However, Classic Rock was published AFTER the old "Easy" climbing grade was scrapped and those climbs now termed scrambles. In addition, any routes which have been regraded since they were first climbed have been noted in Classic Rock. When the book was originally compiled, it was to cover grades up to Severe. Little notes after each route show the current grade, some of which are now as high as VS. However, Tower Ridge has NOT been up- or down-graded since its original grading :)

I'd agree with Cath that 3 or 3s can overlap with Mod, and MAYBE Diff, but if the hardest English grade is 3s, and Tower Ridge is higher, as Dave says, surely it should be given the climbing grade of Diff? For English scramblers, it cold otherwise be misleading. Still, as I said, I'm not familiar with Scottish grading, so I may be wrong
Posted: 29/11/2005 12:05

Cheers Dave, thanks for the clarification. I've no experience of Scottish scrambling as I've only beent here in winter. I've always understood that grade 3 Welsh scrambles would be mod climbs and possibly have bits up to diff
Posted: 29/11/2005 12:18

Cara, first of all it's only my personal opinion that Scottish grade 5 is harder than English/Welsh 3S. However, I can confirm that it is also graded as a Diff. In the grading of routes on OM I try to follow the conventional grading as previously published for scrambles - but perhaps where the high end scrambles it would be more helpful if I also put climbing grades where applicable (say for Diff and above)?

Fortunately there won't be anything harder than Tower Ridge to cover in future, but other scrambles such as The Cuillin Ridge and sections of An Teallach Ridge will also be graded 5 with sections that also qualify for a climbing grade.

What I would like to point out is that I deliberately left out the V Diff alternative start that goes over the Douglas Boulder and that there were several references to the fact that this is an extreme route at the highest end of scrambling.

Grading is always going to be a problem - even rock climbers can't agree on their grades half ther time. While Tower Ridge is as hard as scrambling gets I personally know several people who've either/both soloed it or done in as a pair but unroped. In the description, however, I mention that ropes and pro are essential, and provide an accepted escape route before the crux sections.

At the end of the day there will never be a universally accepted, objective, grading methodology - so all I can do is explain the methods I choose for giving the grades I give. After discussion with Jon I will shortly be writing an article on grading scrambles, and in particular how I grade the scrambles published on OM. This article will be linked from all future scrambles to minimise confusion. To be honest though, personally I'd prefer English/Welsh grades and Scottish grades to work to an identical system - perhaps something for the UIAA to look at globally too.
Posted: 29/11/2005 12:28

Agree there Dave :)
A universal system would make it a lot easier to relate to overseas guidebooks etc! Can't see it happening though!
Posted: 29/11/2005 12:31

I'm not so sure that Andrew Dempster's "Classic Mountain Scrambles In Scotland" is actually the Scottish grading system anyway

Noel Williams' "Scrambles in Lochaber" and "Skye Scrambles" use the normal 1-3 system.

Then of course you've got J. Wilson Parker's "Scrambles in Skye" which is different again!
Posted: 29/11/2005 12:44

All my scrambling has been in Scotland, and the only time I've ever used a guide book was on Skye, when I used the excellent "Skye Scrambles" book. This is the Noel Williams one, published by the Scottish Mountaineering Club.

It has 3 grades of scramble - then it's climbing grades.

If that's good enough for Skye, why would we need another system?
Posted: 29/11/2005 12:48

Headcammer Productions also use the 1-5 system for scrambles in Glencoe on DVD, but S.Bull doesn't use any grades at all in the Black Cuillin Ridge Scramblers Guide.

Personally I'd be more than happy to use the 1-3(s) system across the board, but that would either rely on my opinion of how a grade 4/5 equates to the 1-3S rating or mean that some routes at the high end get left out alltogether. Interestingly Noel Williams chose not to include Tower Ridge in early editions of Scrambles in Lochaber, but now includes it as a grade 3S. I can't honestly see how a 3s grade for Tower Ridge, with 4,000+ft of sustained exposed scrambling, compares to something like Grey Crag in the Lakes.


Posted: 29/11/2005 13:05

Without wanting to muddy the waters still further, I think there should be some cognisance taken of whether the route is tackled in ascent or descent. I can think of many routes where it would be a whole different ball game if it was one-way only. And that's one of the differences between scrmbling and climbing. The latter tends to be an end in itself - climb to the top via a difficult route and walk back down, whereas scrambling is often required (or enjoyed) as a two-way route.


Posted: 29/11/2005 13:15

Personally I'm quite happy descending grade 1 scrambles and would consider grade 2 routes in descent, but I wouldn't want to descend a grade 3 route. And from what I've read of tower ridge no way would I try to descend it (unless I abseiled it!)
Posted: 29/11/2005 13:22

Since there are different views of how routes are graded, perhap it would be a simple solution to just mention that. Adding that Tower Ridge is widely regarded as a diff climb is only a few words but adds a lot of clarity for a lot of folk.
Posted: 29/11/2005 15:44

Dave,
I strongly support what you are doing but when you go to print you should be open & honest about the grade, the SMC are the governing body for the area, look in the latest SMC difinative climbing guide for the area, if it says diff thats what the grade is, end of story.

You are admitting yourself, that its very difficult to accurately grade scrambles and scramble grades are inconsistent across UK.

Tower Ridge has been graded diff for over a century and everyone was happy with it, why suddenly change.

By the way I have descended tower ridge unroped several times its the descent route for a lot of ice climbs.



Posted: 29/11/2005 16:33

Kit,
I am being totally open and honest about the grade! It is a "Diff" and a grade 5. The two grades overlap at this point.

As for "why suddenly change" - I refer you to the publication listed above, printed in 1992. It is not a sudden change. Further evidence is its inclusion in Noel Williams' book Scrambles of Lochaber - In which it is graded as a Diff, but still classed as a scramble.

Unfortunately the SMC do not publish a Scrambles in Scotland. It would be interesting to see if Tower Ridge appeared in it.

I understand that people need to know the true grade of a scramble - in relation to others -to judge whether it is within their capabilities, but I really don't see where the problem lies in accepting that at certain points the grades overlap. Why can't it be both a grade 5 scramble and a Diff climb?
Posted: 29/11/2005 16:50

"Why can't it be both a grade 5 scramble and a Diff climb?"

In that case why not mention both grades in the writeup? Keeps everyone happy. :-)
Posted: 29/11/2005 16:55

"but perhaps where the high end scrambles it would be more helpful if I also put climbing grades where applicable (say for Diff and above)?" is what I suggested earlier Geoff :)

Btw Kit, although the SMC publish the guides they do not set the grades nor do they have any function in rating the grades. grades are generally agreed by concensus. I agree their series of guides are superb, and the best available, but their regional governing body status has nothing to do with the actual grading of routes.
Posted: 29/11/2005 17:03

Ooops, missed that bit in your earlier post. Excellent. Smashing stuff.
Posted: 29/11/2005 17:09

Dave, Carry on the good work, there is no reason why a route cannot have 2 grades, just amend the review and nobody can criticise you.

This is not the place to discuss SMC guidebook politics.

You know as well as I do, that if you want to check a grade of any route in the country you look in the latest difinitive guidebook for the area.

The bible.
Posted: 29/11/2005 17:34

> Re: although the SMC publish the guides they do not set the grades nor do they have any function in rating the grades. grades are generally agreed by concensus.

I'd like to pile in here and support everything Dave says. Not only are grades agreed by consensus, but Dave or anyone else is perfectly entitled to give their own opinion of the grade, and dictate their own grading system in their own write-up. Grades are always subjective and there will always be disagreements because no two people are the same.
It's important to remember that the grade is just a guide, and so is the route description. Ultimately everyone embarks on scrambling and climbing at their own risk and you can't blame the guidebook writer if anything is different from your expectations.
I do think putting the climbing grade in as well is a good idea where they overlap, if only to re-emphasise the potential seriousness of routes like this in poor conditions or with less confident or less experienced party members who may think a scramble is supposed to be an easy option.
Posted: 29/11/2005 17:37

Cheers Kit,

The problem is that different people prefer different guidebooks (eg Brian Evans' Scrambles in The Lake District or the FRCC guides, CC guides or Scrambles in Snowdonia) They're made for different audiences but cover the ground.

In future I'll include climbing grades of Diff and above where applicable, and I'll have a word with Jon about putting Grade 5/Diff climb on the grading.
Posted: 29/11/2005 17:40

Thanks Alison, especially for the reminder to us all about the grade just being a guide. Fortunately grading in scrambling is actually easier than in climbing, wher some people deliberately undergrade to make themselves appear better, some overgrade because they may be near the top of their limit- or just be having a bad day on the rock.

As always when grading comes up, it's been a good discussion. What is important to say in general is as Alisom pointed out -that no matter what the guidebook says it is up to the individual to continually assess risk in terms of their ability. To this end it is advisable to go "through the grades" in scrambling and familiarise yourself with the level of difficulty expected. This way if you should find yourself on a single grade higher (in your opinion) it won't be drastically above your prior experience.
Posted: 29/11/2005 17:52

I fail to see how Dave was not being honest and open in this debate. Dave has always been open and honest on these forums.
Dave has been (and I'm sure will continue) doing an excellent job with his routes. And unlike the authors of the guides mentioned above, is able to take part in discussions about the details of his routes.

As has already been pointed out grading is subjective at best. I have no problem with what Dave has used as his grading system. The idea of a linked article about the grading system used hopefully will clear up and put to an end this sort of discussion.

Dave's advice in his last post about going through the grades, is a sensible one, and one adopted in Hillwalker's guide to mountaineering.


Keep up the good work Dave.
Posted: 29/11/2005 18:25

Dave,
I think that is a good conclusion, I also think Dave is doing an excellent job, now we are going to post climbing & scrambling grades it closes a loophole, even better.

One thing you mention about grading of rock climbs, it is very difficult to grade first ascents accuratly, I have done new routes, second ascents and many climbs that have been written into the guidebook unchecked.

One reason for making 1st ascents difficult to grade is that you often have to clean them, so you know where holds are when you lead them.

A reason for undergrading is that if you overgrade it leaves you open to critics.

On second ascents you often have beta, if not the grades can be all over, doing a second ascent without beta can be really scary.



Posted: 29/11/2005 19:38

Thanks for the support everyone :)
I'm always happy to either justify my routes/grades for both walks and scrambles for a variety of resons:
1) Routes and grades are only my personal choice and opinion and I'm no more infallible than any other person
2)If people are arguing with my routes/grades it means at least someone is reading them :)
3)Grades are forulated by concensus and concensus changes over time
4)Healthy debate never does any harm
5)You can always learn something from someone elses viewpoint

So please feel free to question - you can be sure I'll reply :)
Posted: 29/11/2005 19:48

I am an old fogy who was rather shocked to see Tower Ridge classified as a scramble. I've never thought of it as anything other than a rock climb. So I'd like to ask Dave some questions (and anyone else who might have an opinion) and maybe give him something to think about when composing his forthcoming piece. So Dave - is a scramble only a question of grade, or is there something else? Situation? Continuity (or lack of it)? If Tower Ridge is a scramble, is any Diff a scramble? What about, for instance, Archer Thompson's route on Cioch Upper Butress. It's a Diff, but is it a scramble? If not, why not?
Posted: 29/11/2005 20:02

Jim,
To me a scramble is more than a question of grade - it's a question of aesthetics. A scramble should ideally take a natural line, for example an arete, chimney, corner etc, as far as possible. When grading I take into account numerous factors including: grade, exposure, sustained commitment,navigability of the route, quality of the rock. In terms of grade I consider the minimum requirements for a scramble to be the need for the use of hands as support, and the high end as being a Diff climb where a rope is advisable for most people for the majority of the route. Within these parameters I also take into account both direct comparison with other routes of which I have personal knowledge and previously published concensus reached grades.

Despite all this, it still comes down to personal opinion of both the writer and the scrambler.

Hope this helps
Posted: 29/11/2005 20:23

One of the problems is that Dempster's guide, the only one I know that uses an 1 to 5 grading scheme, which is fine.. if you have the book, as the explanation of HIS grading system is given there. It classifies the CMD arete as a grade 1 (you aint going to use your hands on this unless you fall over!) and the Ledge Route as a 2 which is a grade 1 in any one elses book.

I have done both as well as a few others and the Dempster's guide does tend to be one grade above the usual.
Posted: 29/11/2005 23:01

But what do I know, I don't even like malt loaf!

Posted: 29/11/2005 23:04

I've just amended the grade on the Tower Ridge route so that it's clear that some guidebooks rate it as a Diff rock climb. I've also pointed out that it's a graded winter climb and not for novices.
Posted: 30/11/2005 13:03

Thanks Jon :)
Posted: 30/11/2005 13:07

Thanks, Dave & Jon, the winter grade had crossed my mind but didn't dare mention it.

Good discussion, good result, we can put it to bed now.
Posted: 30/11/2005 13:28

We can put the Tower Ridge issue to bed, but have you any thoughts on Jim's questions?
