of the flat pettles kind, I have now come about
one-quarter mile further anticlinal away.
I have gone south another one-quarter-mile
and the same sandy limestone with granular and
flat pettles intraformational conglomerates continue.
It is a higher series than the proiliforms ever
seen first near Marathon.
One mile further south I see the same white
[illegible] shale
shale looked at Saturday. The white shales
or Ordovician Armaculites, I should be
rising in the strata to it. In places current
last then are some syncline folding to the
west. Apparently the dips are not uniform, but
are somewhat rolling.
As we goes south I think one rises in the sec-
tion, and passes fine shales with thin beds of lithographic
limestone and once and once sandy materials with shales.
Throughout the intraformational congl. are present.
