All Mixed Up is one of Rocky Mountain National Park's classic winter ice climbs on the southeast flank of Thatchtop Mountain in Glacier Gorge. The consistent steepness and thin delicate structure are a great option for ice climbers with a little bit of experience who are ready for a bigger challenge beyond single pitch. With thin and difficult to protect ice low on the route and an approach that s long enough to make it a full day climb it's best in early season.

The approach starts at the Glacier Gorge Trailhead and follows the trail to Mills Lake, then continues off trail through the downed trees to the base of the climb, a hike that can run two to three hours depending on snow conditions. We like to do this climb early season when it's easier travel. If the party has to break trail it can become pretty tedious. We generally guide the route in 4 pitches, a low angle first pitch that's often thin and hard to protect, a section of short, steep ice steps, and a final bit of steep snow leading to the final pillar where you finally get some of the thickest ice of the day. The most common way to descend involves walking off but during more intense loading avalanche conditions might make rappelling a safer option.

We guide All Mixed Up as a full ice and mixed climbing day. Conditions on this route change through the season and year to year, thin one week, fat the next, so talk to us about current conditions before you book. As one of six authorized concessionaires we can give you our most current conditions report and let you know if it's worth it or if back up plans are a good idea.
