Aug 2-99 Wednesday Camp VI & VII Broke camp and left Trege But just by 9:30. Shipped to Larumie 2.3 acts of fossils. Hambach, Todd, Carlson and Culberton left for home. During the afternoon we passed another uplift of Jura-Trias in which the Triassic rocks formed cliffs from 700 to 800 feet high. The structure here is about as at Trege But Int. Took my pictures of these hills. Are an 40 M. from Medicago Bow. By 5:30 are camp at Sullivan's Ranch in Shirley Basin near high hills of granite and Paleozoic rock. As soon as camp is pitched I start out for the hills and find them farther away than I had expected. The structure is due clear in places. A rapid run of 1 1/2 hours revealed a number of strata which struck to be Cambrian and then Paleozoic strata with a fault cutting off the Jura-Trias.
