Pitkin County's 40.7°F annual temperature runs 6.8°F below the U.S. median of 47.5°F, confirming its ultra-alpine status.

Aspen-grade mountain infrastructure required

Residents must engineer for 170+ inches of snow, requiring roof reinforcement, industrial removal equipment, and constant winter vigilance.
