Henry's Lake

Henry's Lake lies high in a mountain bowl (elev. 6,470 feet) 15 miles from the west entrance to Yellowstone National Park.  With a backdrop of Sawtell Peak, the shallow lake is known for its trout fishery.  The Henry's Fork of the Snake River originates here, just below the Continental Divide between Idaho and Montana.
