They begin at Mica Peak and Krell Hill near Spokane and extend approximately 320 km north (200 miles) from the border to Kinbasket Lake, at the now-deserted location of the onetime fur company post, Boat Encampment.This area, some of it protected in Washington's Salmo-Priest Wilderness, is also home to mule deer and white-tailed deer, elk, black bears, cougars, bobcats, red fox, bald eagles, golden eagles, osprey, great blue heron, porcupine, badgers, coyote, martens, bighorn sheep, mountain goats, gray wolves and moose.The herd was cross boundary, spending some time in extreme northern Idaho, eastern Washington, and British Columbia, Canada.Predation from wolves that had been reintroduced to the area negatively effected the herd, and by April 2018, only three remained,[6] and in January 2019, the American Association for the Advancement of Science (AAAS) announced in its scientific journal, Science, that British Columbia's provincial biologists captured the female caribou in Canada and moved her to a captive rearing pen near Revelstoke in the hopes of "preserving highly endangered herds".[7] According to the AAAS, it is believed that this female caribou is the "last member of the last herd to regularly cross into the lower 48 states from Canada".
