Algal growths, ranging in color from bright green and copper-colored in the hotter water to a dark green in the cooler portions, lined the run-off channels to their junctions with the cold-water stream. Patches of algae also persisted in the cold-water stream, the temperature of which was from 70 to 66 F. down to its junction with Monument Creek, whose water was 55 F.
