(20) 6) Covered - 9', probably gray shale and a few brown vitstone bands- 7) LS, brown weathering, bedding 6", uneven surfaces, Cracid, fractured and a few fucolines. Collection 6/27/57/10 24-7 8') 8) Covered - 12' probably line nodulars in a clay or silt, some brown color - 9) LS, gray, massive a) fucolines and brush cocking in a 6" band at base, Collection 6/27/57/11 (same horizon as 6/24/57/6) b) Massive LS ridges 4 to 6' thick. These form the dp slope and seem to be about 10' below what I believe is P. King's LS # 2 bed. 12' thick (?) (21) In the afternoon 6/27/56, I drove NW from the Wolfcamp hills to a tank (about 1.5 miles). From there I walked slight west-northwest to the low outciers of the "Wolfcamp" Series as mapped by P. King, just below his "New Ledge". I found silt and sandstones with even bedding. These are exposed in a gully... They would suggest that the so called "New Lead" at Wolfcamp Hills is only a local bed or lens. The sandstones are med. laminates - 1/8 to 1/16" and have abundant tube (or focal castings) of worms - one I measured was 5" long, 1/4 in diameter and near straight - - About 2' above this silt/sandstone sequence - the rubbly party the LS. I made Collection 6/27/57/12. It looks like what C.O.D. said Schenckully Keigi would look. - 4' above collection 6/27/57/12, I found a brown shale - it had a few streaks of red-brown at the top and some gray in patches - Collect 6/27/57/13 from shale.
