This is a simple two pitch climb. If the snow conditions are right, then the first pitch should be longer. Bring your skis or splitboard. This is a great skin in, climb, and then ski out on awesome terrain. Be careful of avalanche conditions!

P1 - ~180 feet, WI3. This is the money pitch. There are a few steps to overcome. Great ice!

P2 - ~30-60 feet, WI2. The first 30 feet of the second pitch might only be WI1, we unroped and walked it. The second half was maybe 30 feet.

Descent - from the top of the climb, head west across easy terrain to where you can start going north easily again joining the route that you came up on. Then reverse your approach route.

For more pictures and my full blog post go to:


Go to the Zimmerman Lake parking lot in the Poudre Canyon. This is past Bald Mt. and close to Flattop Mt. short of Gould. At the parking lot, you can see the cliffs to the south and slightly west, this is where the climb is. It is about a 2 mile approach (and about 2,000 foot elevation gain) to the climb. From the main Zimmerman Lake trail, take a right into the trees pretty quickly (we followed skin tracks). Gain elevation while traveling southwest. Once at the treeline, continue southwest and skirt around a bowl (you should see the cliff-band where the climb is). Be very careful about avalanche terrain and traps!

I would not suggest doing this without skis or a splitboard. I couldn't find my snowshoes the day we climbed it and had to post-hole for 4 hours. I believe that this area is skinned up to once in a while, so use those.


Screws should be all you need. Bring 20' anchor cord/webbing for the top of P1.

This flow is commonly known as the Iron Mountain Icefall. It was first climbed in the '70s. Nice little piece of Poudre ice though - but I wouldn't call it Grade IV.

Thanks Andy, I will change it. I had asked around when I first climbed it but got nothing. An easy search on Google proves it with a video of Rodney.

Climbed this on 2/27/2016 in fat conditions. Avy risks were relatively low, but there were still a lot of wind-loaded pockets, so we decided to not walk off the top as described in the beta photo. Instead, we were able to rap off a tree near the top of P1 (there was some newish looking cord there... we added some new webbing anyhow). We were just barely able to make it down in one rap using a single 70m rope. Even with the rappel, it still makes for a LONG day.
