8/8/58 went up river boat Call 8/8/57/1 from Great Canyon near lower Eagle Ford, Shickel but 3400 day total 2/6/58 Proceeding more slowly now, but about 12 mile The Canyon closed the width of 10-30 feet and seems to be projecting considerably away from the walls. Bored this year a natural, there is a 50'-90' limestone layer and some shale below it. There a program call 2/8/57/4 has 30 of shales near Ridge Creek, 640 150'-200' from the upper part, the western New Chief Trail is equivalent to the natural above the last studied below. The natural seems to be restricted to the marine limestone (and shale, which are intruded) and white limestone in term, escaped to Colorado. In the Colorado were calculated to a distance; the present may be the initially factors. The fault on the North side this fault seems to cut the Leonard (light) limestone, but to sliver westward and become hiding some faults in the shale interval at the top of the 'Wet Canyon' - general. Call 8/8/57/1,3,4 are probably from the same Camp as 5/2/58/3 and 8/2/57/5 I believe many the 'Wet Canyon' section above the Coulee on the western end of this is missing as result of faulting.
