Terrestrial Maternity Denning of Polar Bears in the Eastern Beaufort Sea Area

Observations on the location of polar bear (Ursus maritimus) maternity dens, the locations of females with young cubs on the sea ice just after leaving their dens, and observations of Inuvialuit hunters were recorded in the eastern Beaufort Sea area from late March to mid-May 1971-79 and 1985-87.
