Most geologists are familiar with the Touchet Beds of the Walla Walla Valley and Pasco Basin that formed upstream of Wallula Gap in slackwater Lake Lewis. This video provides a quick look at one roadcut along Hwy 74 near Cecil, OR. Here, Touchet-equivalent deposits were laid down in a similar slackwater setting, but in Lake Condon which formed upstream of a constriction near The Dalles. Missoula flood rhythmites are exposed in roadcuts for several miles along the rural, two-lane Heppner Highway. About 15 sand-silt beds that host the dikes are exposed in the Willow Creek area. The location is 55 miles southwest (downstream) of Wallula Gap and 12 miles as-the-crow-flies from the Columbia River. The Willow Creek drainage is part of the larger Umatilla Basin. Same dikes, same deposits, same floods, different lake basin.
