Winter reads better from a slopeside window

Every one of those blue bars fell as snow on the runs behind the lodge. The lifts turn again in December — watch the first storm arrive from fifty yards away.

Davis weather station on the Brettelberg lodge at Sunlight Mountain Resort, 8,200 ft — one reading a minute since Aug 23, 2025, aggregated hourly and daily. Days are bucketed in UTC, the gauge under-counts snow, and the anemometer only knows what happens at the roofline. It’s our weather, honestly kept.
