It formed during the latest period of glaciation roughly 10,000 years ago. As glaciers retreated in the Chicago Creek valley, lateral moraines formed a natural dam to drainage, forming the lake. The ecosystem around the lake is dominated by Engelmann Spruce (Picea engelmannii) and Subalpine Fir (Abies lasiocarpa), with some Limber Pine (Pinus flexilis) on exposed sites.
