158 [illegible] walking over the outcrop as far as the Desie fence line there seems to be no exposure of rocks other than those in section 22. The green-brown silty sands (Raymond?) is in a very tight syncline or overturned anticline which strikes near E-W parallel with the faults at Leonard. I believe the displaced rocks are faulted down because I can trace this structure about a quarter of a mile. The [illegible] Colorado breccia zone is quite thick here (40 to 50') and has an upper surface which appears slaved out. It dips steeply to the N (at [illegible] as much as 55°). This surface has since been distorted and is now cut by many 2ndary faults. The complete field relationships of these beds are unfortunately [illegible] concealed. Coll. 8/2/57/7 - Blue shale 20' interval below Alexis Is ledge, N45°W of Desie well near windmill. 159 Coll. 8/2/57/8 - Biolumal or Biothermal zone in base [illegible] Congs. (G.A.Copper locality) almost due west of Desie well- near windmill. It would be nice to check the outcrop on the Den Ald Ranch that P King mapped as [illegible]. The Leonard Aff section will have to suffice. Why should P. King have missed this important structure by the Sullivan Ranch Road? Probably didn't walk over it (?) 8/3/57 - Shipped 138th rock specimens in 3 packs, the heavier two were double gunny sacks. End of Book one 1957
