This image was made at a spot on Little Spearfish Creek about 3/4 of the way down stream from Rough Lock Falls in Spearfish Canyon. The temperature was well below 0 deg/f and had been for several days but, except for some paper thin ice at the edges, the water never freezes. Its always baffled me because further down stream and at lower elevations the creek freezes solid. Comment by clicking on the title above if you know the answer.
