The 2003 Aspen Fire destroyed 314 of the village's 467 homes, so much of what stands today was built after it.

Up here the climate flips. The 1991-2020 normals for the Mount Lemmon Willow Canyon station, at about 7,047 feet, show a January normal high of 49.6F and low of 33.5F, about 53 nights a year at or below freezing, and about 4 days a year that never get above freezing. Annual heating degree days run about three times the airport's. Pima County puts land at 4,000 feet and above in code climate zone 5B with a winter design temperature of 4F.
