Country: United States
State: Wyoming

Coordinate: 41.82° N, -110.86° W
Basis of coordinate: estimated from map
Geography comments: "a 21-km section of U.S. Highway 30 situated in Southwest Wyoming, in an area locally known as Nugget Canyon... Elevations along the 2-lane roadway ranged from 1, 890 m to 1, 950 m"
Habitat: desert/xeric shrubland
Protection: unprotected
Substrate: ground surface
Habitat comments: "The canyon was characterized by steep sagebrush (Artemisia tridentata) canyons and open hillsides"
Life forms: carnivores, ungulates
Sampling methods: line transect, automatic cameras
Sample size: 51416
Years: 2008 - 2011
Days: 729
Seasons: winter, spring, autumn
Nets or traps: 7
Camera type: digital
Cameras paired: yes
Trap spacing: 3.500
Sampling comments: "We installed 3 digital infrared Reconyx® (Holmen, WI) cameras in each of the 7 underpasses, including one at the entrance, one in the middle, and one at the exit... Underpasses were equipped with cameras from 1 October through 31 May for 3 years. The study period encompassed autumn migration (2008, 2009, and 2010), winter use, and spring migration (2009, 2010, and 2011)"
the study therefore spanned 243 days/season times 3 years = 729 days
spacing was 21 km/6 traps from the start = 3.5 km
