The Wolverine Glacier weather station was installed in 1968, and at 3250 ft is the highest elevation long-term weather record on the Kenai Peninsula. On October 19, 2020, USGS scientists upgraded the power system to a Lithium battery bank and installed a radar-based precipitation sensor (Lufft WS-100) to compare with the weighing based precipitation gage.
