When first discovered the glacier bear was supposed to be a distinct
and well-marked species. Recently cubs representing the glacier
bear and the typical black bear have been found in the same litter,
thus proving it to be merely a color phase of the black bear. Its
color varies exceedingly, from a light smoky, almost bluish,
gray to a dark iron gray, becoming almost black. Some individuals
are extraordinary appearing beasts, quite unlike any other bear.
The interest in this curious color development is increased by its
restricted distribution.
