[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.

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.
