Read this excerpt from "close encounters of the bear kind" by susan e. quinlan.

beep. . . . . beep. . beep. . beep. the quickening beeps of the radio signal tell john hechtel two things. he's getting close to a bear den and the bear inside is waking up. bears lower their body temperature less than other hibernators, so they're easily awakened. john and his coworkers crunch loudly as they snowshoe across the crusty snow. bowed-down branches of willow shrubs weave a carpet of shadows over the snow, making it tough to spot the small breathing hole that usually marks a bear's den. the scientists look carefully and move slowly. it's not a good idea to step on a bear that's just woken up. john is a biologist with the alaska department of fish and game. his study area is the tanana valley, a boggy lowland in central alaska. it's prime black bear habitat, but most of the ground is too wet for dens. unfortunately, the only dry areas that seem good for dens also happen to be used by the u. s. army for winter training. so to protect both bears and soldiers, the army hired john to find out where most bears in the area hibernate.
