The gray wolf photo was taken by Glacier National Park snow survey crew working to get The Going To The Sun Road ready for it's very short summer season.
The moose rising was taken on the Rockwell Falls Trail which starts just past the boat launch at Two Medicine Lake. The bear was photographed the same day in the Two Medicine area. Bears can be very active in the Many Glacier and Two Medicine areas of Glacier Park. I went back to Rockwell Falls Trail multiple times that year hoping to get more photos of the moose without any luck. The Swift Current Pass Trail in Many Glacier, particularly Bullhead Lake, is a much more reliable location for observing moose.
Montana wildlife photography
Glacier and Yellowstone are fantastic locations for Montana wildlife photography. Whether you encounter lots of wildlife is as much luck as location. However I've encountered more grizzly bears in Glacier National Park then in Yellowstone. According to park naturalists, Glacier National Park has the highest concentration of grizzly bears in the United States. A few years ago a study by Katherine Kendall of the Northern Divide Grizzly Bear Project was in Northwest Montana and included Glacier National Park. This DNA study of grizzly bears counted some 563 unique grizzlies. That's a lot of bears! Over the last eighteen years I've only seen a small fraction of them. The Washington Post on March 10, 2008 ran a front-page article on this study.
My daughters did encounter seven bears on one hike in Glacier National Park. That was the Iceberg Lake Trail in October. I hiked the same trail in October the year before and could not find any animals other than a few squirrels.
