Book Description
Excerpt from The Geologic Setting of the John Day Country: Grant County, Oregon Thomas Condon Viewpoint, John Day Fossil Beds State Park. From Picture Gorge to the cliffs opposite, the Picture Gorge Basalts and varicolored ash beds of the John Day Formation rise together nearly 2000 feet. The basalt that caps Sheep Rock is an erosional remnant. The lower beds in the John Day Formation are colored red by clay eroded from thick soil on the Clarno Forma tion, which is exposed in the farthest red hill. The soil was formed by tropical weathering some 30-35 million years ago, before the John Day Formation was laid down. Faulting on a small scale is illustrated in Sheep Rock, where the thick olive-drab ash flow in the middle of the John Day Formation is offset 75-100 feet (fig. The fault slopes about 45 eastward. About two miles down stream, large - scale movement on two faults has dropped the basalt flows in Middle Mountain 2000-2500 feet. One of the faults fol lows along the upstream base of Middle Mountain. Fig. 5. - North-south section along the John Day River through Picture Gorge and Middle Mountain.
