One of the most beautiful mountains in the park. the SE face of Ypsilon Mountain is one of the only steep faces in the Mummy Range and is guaranteed to be an escape from the crowds. This 2000 ft face is bordered by ridges on either side forming its own awesome cirque. The left side of the cirque is Donner Ridge, a nice 4th-class hike. The right side is the classic Blitzen Ridge. 5.4 to 5.7? The center of the cirque, the Y Couloirs are reserved for the alpinists. These couloirs hold the remote RMNP alpine experience.

Descent for all Ypsilon routes- either run down the backside to the trail head on Fall River Road (provided it's open). 2nd choice, descend Donner Ridge, or into the cirque between Ypsilon and Chiquita and back to Ypsilon Lake.

Getting There 

Approach- find the Lawn Lake trail head and trudge on up to Ypsilon Lake. From there take a less obvious trail NW and try to find Spectacle Lakes (a great place to be!). From here the Y Couloirs are straight ahead in the middle of the face. Donner is to the left and Blitzen is to the right.

Thanks to its beautiful rock and wild position in a wilderness setting, Blitzen Ridge is perhaps the best ridge climb in the Park.Don't be fooled by the 5.4 rating. When planning for this route, keep in mind that you'll be climbing a rather commiting, lightning prone ridge which is blind to approaching storms. Soloists in good alpine shape should find themselves on top of Ypsilon by late morning. Roped parties must take extra care to move fast and efficiently.If sending the whole shpeal in a da...[more]   Browse More Classics in CO

This is truly a beautiful and worthy mountain for any solo hiker who wants some adventure off of the beaten path. I climbed the southern left ramp of the mountain in 2010 solo. It's pretty much 4th class talus scrambling the whole way up but was still rather committing for a solo ascent (I believe this may be the descent route for some parties who are ice climbing). To do this line, you have to cut into the valley to the left of the cwm.
