GPS station P361, on Sawtell Peak

GPS station P361, on Sawtell Peak, on a nice clear day. Electrical storms destroyed multiple antennas, including the GPS antenna--here under a protective plastic dome--and three communications antennas on the tower. Data from P361, along with data from other stations in the Yellowstone region, are sent to UNAVCO for free and open distribution. (Photo by UNAVCO staff)
