Throughout the eruption, scientists installed monitoring stations to track volcanic activity, deployed temporary monitoring ""spiders"", monitored the temperature of lava spines and created time-lapse of dome growth. During the 3+ years of the eruption, lava piled up to form a new dome 460 m (1,500 ft) high.

Events that occurred in the crater during the 2004–2008 eruption were recorded by a network of seven remote, telemetered digital single-lens reflex (DSLR) cameras installed on the crater floor and rim. The resulting time lapse images constitute a valuable and visually compelling record of dome growth and the resulting response of Crater Glacier.

Grizzly bear paws and licks one of our remote cameras and eventually pushes it off the tree. The camera container had a screw top lid that moves as the bear paws at it; the camera was not damaged (Make sure you have your sound on for this).

Grizzly bear goes under barbed wire into a hair snag station, sniffs scent lure pile, and leaves. DNA analysis of hair deposited on the barbs identifies the bear for a study of bear population size.

Grizzly bear climbs over barbed wire at a hair snag station near Glacier NP, Montana. DNA analysis of bear hair is used to identify individuals as part of study to determine the size of the bear population.
