Fusillade Mountain (8755feet) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.[3] Fusillade Mountain lies immediately north of Gunsight Lake at the western terminus of the St. Mary Valley and can be seen from the Going-to-the-Sun Road. The mountain was named by George Bird Grinnell in 1891, "as a satirical gesture at W. H. Seward and Henry L. Stimson for firing a futile volley at a group of goats on the side of this mountain".[4]
Like the mountains in Glacier National Park, Fusillade 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 31NaN1 thick, 50miles wide and 160miles long over younger rock of the cretaceous period.[5]
Based on the Köppen climate classification, it is located in an alpine subarctic climate zone characterized by long, usually very cold winters, and short, cool to mild summers.[6] Temperatures can drop below −10 °F with wind chill factors below −30 °F.
