 Because of its remote location and relative inaccessibility, climate records are poor. The nearest weather station, Potato Hill, has only been measuring precipitation since 1982 and temperatures since 1989. Temperature and precipitation records from Glenwood and Trout Lake, both considerably lower in elevation and further from the mountain, are more complete and go back further, 1948 at Glenwood and 1924 at Trout Lake. Snowfall records from the three snow stations on Adams cover a number of years but are discontinuous and are limited to the northwest side. The Potato Hill station was monitored monthly from 1950-1976 and was replaced in 1982 with the automated precipitation sensor. It was upgraded in 1983 to report snow water equivalent and it was upgraded again in 2006 to report snow depth. The Council Pass station was monitored monthly from 1956-1978 and the Divide Meadow station was monitored monthly from 1962-1978. Divide Meadow was the most representative of the snow depth on the west side of Adams because it was the highest station on the flanks of the mountain.
