 Ages
ago a river flowed across the high desert country in the rocky canyon
several hundred yards beyond the marker. The prehistoric river drained
a large ice age lake that formed from the blocking of normal drainage
in the area by lava flows. The lake covered a large area to the east
in the vicinity of the present millican country. During periods of
high water the lake spilled over a low pass at the eastern edge of
horse ridge-the ridge seen behind you and to your right. The escaping
water cut into the loosely consolidated lava flows creating the rocky
gorge visible from the viewpoint and later called Dry River. Once
free from the horse ridge barrier dry river flowed north into the
present Crooked River. Evidence indicates that the ancient river was
once the scene of many Indian encampments near its source at the lake. |
