Site Weather
Commissary Ridge Fall 2022
Commissary Ridge has high overall volume and diversity of raptors and is both accessible and logistically well-suited to be a long-term migration monitoring site. HWI conducted the first full-season count in 2002 at Commissary Ridge and has continued full-season counts each year since.
Directions
From Evanston, WY, head east on I-80 for 13 miles. Take U.S. 189 north to Kemmerer and continue 1 mile north of Kemmerer to Frontier, then turn northwest on State Rd 233. Continue for about 16 miles to Lake Viva Naughton/Viva Naughton Reservoir (before reaching Lake Viva Naughton, you will pass another smaller reservoir). At the southeast tip of the Lake Viva Naughton, turn right on a 2-track dirt road (unmarked BLM road, look for a small sign on the fence about 30 feet from the main road). Continue down dirt road to the ridge, about 6 miles. Camp will be on your left. Walk up the ridge to the observation area.
