Mount Siyeh is rather easily accessible from a variety of different routes. It can be ascended via a long scree scramble from the Preston Park area, or from Piegan Pass via Cataract Mountain. The summit can also be reached via a long hiking/mountaineering route dubbed the "Skyline Experience"; this route starts from the Many Glacier Hotel and involves 5.5 miles (9 km) ridge walk and includes the summits of Wynn Mountain (8,404 feet (2,562 m)) and Cracker Peak (9,833 feet (2,997 m)) before reaching the top of Siyeh.[4][5]
Route Descriptions can be found on Summitpost or in A Climbers Guide to Glacier National Park.
Geology
Like other mountains in Glacier National Park, it is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was initially uplifted beginning 170 million years ago when the Lewis Overthrust fault pushed an enormous slab of precambrian rocks 3 mi (4.8 km) thick, 50 miles (80 km) wide and 160 miles (260 km) long over younger rock of the cretaceous period.[6]
Climate
Based on the Köppen climate classification, it is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers.[7] Winter temperatures can drop below −10 °F with wind chill factors below −30 °F.
The peak of Mount Siyeh has a tundra climate (Köppen ET) or an Alpine climate.
