Eagle Lake Area of Critical Environmental Concern is 5,100 feet above sea level in northeast California and subject to harsh winter conditions. Having no natural surface outlet, Eagle Lake is a closed basin lake with its water levels fluctuating with variations of inflow. As temperatures drop below freezing, fascinating ice formations form on the surface. Photo by Bob Wick, @mypubliclands
