Upson Lake lies in the first inland valley from the shore of Lake Superior and is a natural shelter for waterfowl.

The sanctuary contains five natural community types which are northern mesic forest, emergent marsh, submergent marsh, northern wet meadow, and rich conifer swamp. The forested portions contain thick stands of large red pines, several large white pines, plus balsam fir, white spruce, tamarack and white cedar.

The sanctuary is located adjacent to the Brockway Mountain Drive with parking available on the side of the road. It is classified as a B sanctuary and therefore, may see visitation by the public during the daylight hours.
