West Green River elk herd locations in southwestern Wyoming, 2005-2010

Between 2005 and 2010, 61 adult female elk were trapped using a baited corral trap on Fossil Butte National Monument during winter. An additional 12 female elk were darted from a helicopter during the winter of 2007 near Cokeville, WY, located approximately 20 km northwest of the Monument. We affixed all elk with GPS collars programmed to collect location data every 5 hours. In total we collected 209,250 locations over the study period for ~141 elk years of data.
