Cloud Peak Wilderness: Pristine alpine rock climbing in northern Wyoming

Far from any road, Cloud Peak Wilderness features over two dozen glacier cut walls and spires towering over the high plains – one of the most pristine alpine climbing destinations in the western US.   We’re keen on keeping it that way, minimizing our footprint as we explore the spectacular mountaineering and alpine climbing in this area.  Our guides work to keep climbers safe and reduce their impact in hope of preserving this pristine environment for generations to come.

Approaching an alpine climb in Cloud Peak Wilderness

Although there is little documentation of alpine climbing in the Bighorns compared to surrounding ranges (intentionally so), there have been a few attempts to fill in some of this interesting history.  Despite being dated, the best resource and guidebook for the area (and for many other remote climbing areas in the state) is Bonney and Bonney’s (1977) Guide to the Wyoming Mountains and Wilderness Areas, which is long out of print but pops up occasionally at used book stores.  A history of the early days of surveying and climbing in the Bighorns can be found in Jack Smith’s (2018) Cloud Capturing Summit

Classic alpine rock climbs in Cloud Peak Wilderness:

Thundercloud Arete (5.8)
  • Thundercloud Arete (5.8, 1000’, 6 pitches) – Thundercloud Arete features six pitches of aesthetic climbing and positioning beside Yosemite-like big walls. The approach meanders through boggy meadows up to one of northern Wyoming’s most iconic hanging valleys. Then we scramble up a small scree field to the base of the arête. The route follows the largest left trending arete to the left of the main overhanging wall of Thundercloud’s massive north face, following the path of least resistance up the ever steepening and narrowing arete.  Note that due to permitting restrictions this trip is only available for booking after September 1st on weekdays.
High on the SE Arete of Cloud Peak (5.8)
  • Southeast Arete of Cloud Peak (5.8, 1200’, 8 pitches) – Livid granite, wild exposure and positioning next to the massive walls of the Merlon – this is a route to write home about! The first pitch has several options with the cleanest line beginning at the very base of the arete and ascending a corner system with large cracks slightly left of the crest, working its way past fun features with several ledge options for a belay.  Pitch 2 can be linked with Pitch 1 if using a long rope and follows the arete to easier fifth and fourth class terrain.  Pitch 3 starts at the base of a double finger crack system and climbs behind an impressively poised boulder to another good belay ledge.  Pitch 4 ascends a left-trending series of good faceholds with a few runouts before reaching another decent ledge.  Pitch 5 ascends one of several handcracks straight up the arete or an easier variation with less protection moves left on a large ledge and follows juggy holds to a large horizontal ledge (it is possible to exit the climb via this ledge with a few exposed fourth class moves on wet rock – a rope is highly recommended here).  Pitch 6 follows the arete on stunning rock to a beautiful topout overlooking the Merlon to the East.  Gain the summit plateau and descend via the obvious Class 2 South Ridge to the saddle between Cloud Peak and Bomber Mountain.  Gear: nuts, double rack of cams .3-2 and one 3.  No fixed anchors.
