BEFORE TOURISM
Before the resort map
The linked local overview does not preserve a clear account of Arapahoe Basin before modern tourism.
This edition leaves that part of the timeline open rather than mistaking the first surviving sporting reference for the beginning of the place.

THE LIVING MAP
The mapped place
Arapahoe Basin is recorded at 39.642° N, 105.872° W. Its catalogue reference reaches 4,020 metres. A modern resort map compresses terrain, exposure and access into a diagram. This exhibition keeps the underlying contour visible so the place does not become only a list of facilities.

TODAY
Arapahoe Basin now
It continues to run lifts until June, sometimes lasting well into the summer, and since snowmaking was installed in 2002 it often begins its ski operations in mid-October.
