The Yellow-bellied Marmot lives at higher elevations in the Rockies, Sierra Nevada, and other mountain ranges. It's a large rodent related to the ground hog that lives in burrows among boulder fields. We saw this one during a backpacking trip along the Teton Crest Trail on the Death Canyon Shelf after crossing over the Fox Creek Pass. It didn't seem to mind our presence at all and we were able to get this shot from a distance that didn't cause it any concern about our intentions. There had been thunderstorm activity on this day and it seemed the marmot was trying to warm up on the rock.
The Teton Range in particular has a high incidence of melanism among the yellow-bellied marmot population. Melanism is a condition where the animal's skin and fur has a lot of pigment and appears all black. It's the opposite of albanism, in which an animal has no pigment and appears all white. We did see a melanistic yellow-bellied marmot on this day. It's shown below for comparison. On previous trips, we've seen a regular colored yellow-bellied marmot and a melanistic one playing with each other near their burrow entrance.
Remember, it's not just a picture, it's a story!
