thanks Fred

Right on, more like $.80 cents if the page is $1.00 :D.
Okay I will find the German system too, though I hadn't heard of it. I'll work on that tomorrow afternoon - in the morning is a ski tour :))

Another Source

Great page. Here is another source you can leverage from. It includes a nice table with various other systems. It'a PDF file from the AAC:
International Grade Comparison Chart

Re: Finally done

After ED follows ABO = "abominable"

for example: Petit Dru - Harlin/Robbins-Route

One of the best I have seen for a while. There was a realy good german one (in german of course and long out of print) which did much the same job

Re: Nice

Thank you! Hey, your profile is very interesting. I'll have to hit you up for some good climb ideas in the alps this summer.

Wish I had seen this earlier!

This is really helpful, I have always been able to understand the Yosemite decimal system, but the others were a bit of an enigma to me. This is a great reference page, thanks a lot!

Thanks for

putting this up. Perhaps you could add the Water Ice (WI) and Alpine Ice(AI) grades here too?

Re: Thanks for

It's a good idea, I will do that when I return from vacation, thx!

Grades II+ and III-


I've found here ( - left and below) that there is no grades II+ and III- for the UIAA. I think that you have included them in your table for comparing with the Yosemite grades but I thought I had to say you.

Re: Grades II+ and III-

Nice, good site. I removed those two grades, especially since I had no comments for them anyway. Thx again, all the best!

Real 3-point climbing

for 2° UIAA - maybe better to explain that 3 point climbing means that one can move only one hand or one foot a time so : 3 fixed point climbing
... somebody intended it as "using" one hand :)

Re: Real 3-point climbing

Thanks Gabriele, I added some explanatory text there.

Great page!

I look at some European mountains sometimes and always pull my hair out trying to figure out the difficulty :-). Kind of funny since I am from Europe but only know the US system.

The alpine grade explained

Hi everyone,

You might be interested to know that contributors to published an article explaining the alpine grade. I just translated it to english:

And to think...

I was going to give you compliments on what a complete and effective set of comparisons you've made in the rating charts, giving real-world examples of how the confusing grade matrices apply to actual locations and climbs, but then I noticed that you'd totally missed out on the most important grading system of all!

Gentlemen, you've both forgotten your Washington roots! How can I compliment this page on its thoroughness when you have not included the dreaded bushwhack grading system? The horror! You, sirs, are slackers, clearly not worthy of my 10/10 vote. Harumph!

Re: And to think...

Har! As Beckey said once of Washington's brushiest (and hardest) mountain climbs, "too many Green Spirits." :D

So useful

Always wondered why so many systems, guess we need world wide simplification. since modern mountaineering began in Europe, I give their effluent ways the nod....

Gret article, thanks for putting it together 10/10
