This is is perhaps the most ultra-classic problem at Carter Lake, and is practically a destination by itself. It's located on the steepest overhanging side of the Kahuna boulder. Start with your hands matched on the large half-moon hold, find a way to stick the sloping shelf a few feet up, and then crank a couple more solid moves to top out. Like much of the rest of Carter, it's on fantastic rock, the landing really couldn't be any better, and the moves are truly spectacular. Definitely one of the Front Range's best problems.


A crashpad or two will be plenty for this problem.

I'm really not up on my Front Range bouldering history, so maybe someone a little more knowledgable can help me out with the first-ascent info for this one.

I think it was Steve Mammen or maybe Mark Wilford.

Definitely one of the best sandstone problems around. A variation to Kahuna Roof moves to the slopers then move right along the lip. I heard it was called "Turtle Head". I don't know the grade. Seems harder than Kahuna roof.

I heard that the crimp at the top of the route has now been broken off.

Yup, the crimp on the face below the lip is gone. The lip is good, so it doesn't affect the difficulties much.

Did this on my first visit to Carter. Couldn't do it on my second visit. I hate that!

I flashed a V7 and did Tommy's Arete (V7) the day before and couldn't pull near the second move on this. So, I'm not sure about the grade. Ahem, sandbag.

That problem is sick! A must do! The hardest part of the problem is the second move to the right hand sidepull, after that it's not really too bad.

This is the perfect boulder problem.
Not a single flaw.

Right side pull has broken for second move. Still goes but after all the breaking in the recent years, most would probably consider this to be V6 or maybe even V7. It is a classic though, so maybe V5 should always remain not that that makes much logical sense.

I was on Kahuna recently now that the water is low enough (freaky rain this year) and the side pull seems the same as it was last season. I've always felt that V5 was a bit of a sand bag but certainly not V7.

This problem took me three sessions and felt like V6+, but I was using some crazy heel beta that had me hanging on the second hand hold for way too long. I went back and sent it again with a drop knee to get the second hold and then bumped asap to the good crimp above. This way is much easier, but still harder than V5 I think. This is one of those problems that feels easy when you master it.

Beautiful, exactly how V5 should feel.

Sending Kahuna! This route was amazing. Great movement from start to finish. This one is not over till it's over. It's stiff for a V5 IMO, but either way it's great.

Sand. Bag.

I was here yesterday and heard from another group that the boulder allegedly shifted slightly downhill, making Kahuna stiffer and Beached Whale softer. Can anyone confirm or deny? This was not my first time at Kahuna, and it didn't appear to have shifted; however, this rumor would explain why Beached Whale is a softer V5 and Kahuna feels sandbagged at V5. Thanks.
