Alpine, April 9, 1926. Friday
went to Leonard Int. to see the hills,
tilted and more or less crumpled "Tesnus" (simple?)
formation
under two beds of the Permian. The beds here
in the basal Permian, is about 300 foot thick
and to the S W. varies in a few miles. From
Leonard Int N.E. the thin increases to about
2000 foot and has beneath it the half camps
of the Permian, and the Upper Baptist not to say
anything of the Lower Baptist which may be =
the Tesnus-Simple beds.
The "Tesnus" at my Leonard Int is crumpled,
mere or less fine conglomerate and appears to have no
fms. Apparently higher come in impure limestones
(maybe 20% o crys.),
but are also mere a len fine conglomeratic,
and these limestones are in large part made of a debris
of fossil fragments. Only of these fragments are tiny pieces
of small crinoids, and very rare bits of small
brachiopods that maybe products of the cana
fauna, and Rhynchonella like Lepidoda, crinids.
Large
specules are very common in certain layers, in
supposedly to lime limestones believed to be of the
simple formation. My rare does one see a crinoid
fossil 1/2 inch in diameter. This "Simple Ci"
appears to me to be of a shallow sea bottom that
