24 4) Ls, mud gray, massive, organic fog, crinoid stems abundant; 3' 5) Ls, dark gray, 3" to 6" beds, 5' 6) Ls, light tan or weathered surfaces; 1' beds, silty flocs, speckling darker brown & gray mudrock, 1 or 2 dark Ls layers, (Coll. 8/9/57/6). 6' 7) Covered, dip-slopes, I estimate ~15'(?) to base of Nuss Couple. The Nuss Couple has slumped to a point nearly even with this bed. The Wolcamp is angularly disconformably with the Nuss at this point. 10°-15° Coll. 8/9/57/7 - talus from wolcamp slope near the middle, weild gray SW of Bugout Mt, about 100' below Nuss ledge - These rocks I feel quite certain are from the Wolcamp interval [based on color & grain & general topographic relations]. 25 Coll. 8/9/57/8 - Outcrop about 80' below Nuss ledge, This is not Captain as far as field relations show, I think this is the zone that Coll 8/9/57/7 was originating from. There seems to be a lot of blue-gray shale in this interval. Large Nuss boulders on the slope above. wolcamp
