When they draw the water down in Stillwater Reservoir in the fall, long narrow bands of boulders emerge. I think that they are eskers, glacial remnants formed as meandering streambeds at the bottom of melting glaciers.
Many of these piles aren't far beneath the surface. This lake is not popular with speed boats. Nice for us.
I took this photo two years ago Columbus Day weekend. The lake was lower that year, and the colors more advanced that weekend.
