Iceberg Peak (Montana)

Iceberg Peak (9,149 feet (2,789 m)) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.[3] Iceberg Peak rises more than 3,000 feet (910 m) above Iceberg Lake and is considered a difficult climb due to the steepness and exposure climbers must endure.[4] The peak sits astride the continental divide 1.1 mi (1.8 km) WNW of Mount Wilbur.[1]

Climate

edit

Based on the Köppen climate classification, the peak is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers.[5] Temperatures can drop below −10 °F with wind chill factors below −30 °F.

Geology

edit

Like other mountains in Glacier National Park, the peak 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]
