Aim. Fire! M-1 machine guns retort a rat-a-tat-tat; semi-automatic M-1 rifles pulsate in explosive barks. Shouted cadence calls command ski and marching formations. You stand at the western boundary of Camp Hale — where military training transformed men into winter and mountain warfare soldiers.

While war raged in Europe, a temporary winter and mountain warfare training camp of military barracks and buildings, stables and barns, training ranges, and courses filled this valley. Remnants of Camp Hale are still discernible — its street grid, channelized river, Field House, Climbing Wall, Combat Range on Resolution Mountain to the north-east, and the firing ranges and ski training slope to the south.

The sheer enormity of moving a division of men, weapons, ammunition, equipment, and supplies into battlefield positions in this mountainous terrain demanded specialized training. Maneuvers in mule packing, winter survival, ice and rock climbing, bivouacking (camp setup) in snow and sub-degree weather, aerial tramway and suspension bridge building honed the mountain warfare endurance of the 10th soldiers.

1. Camp Hale (Wikipedia).
Excerpt:  Camp Hale was a U.S. Army training facility in the western United States, constructed in 1942 for what became the 10th Mountain Division. Located in central Colorado between Red Cliff and Leadville in the Eagle River Valley at an elevation of 9,238 feet, it was named for General Irving Hale. Onslow S. Rolfe, who had developed mountain warfare techniques as commander of the 87th Mountain Infantry Regiment, was selected to command Camp Hale.

Soldiers were trained in mountain climbing, Alpine and Nordic skiing, cold-weather survival, and various weapons and ordnance. When it was in full operation, approximately 15,000 soldiers were housed there.
