If any estimates of thickness are correct
and my stepping of a good rod is correct then
the thickness is not over 14460 feet against
the 1685 feet said to have been measured by the
Penn. Survey, However the thickness may be
even less than 14460 feet because of in the
hills side I saw some flexures only the re-
[illegible]
If the 168 foot basal Dalinga is doubled as seems
probable then the thickness is 1608 feet.
On the Penn. side the Shawangunk can be
counted easy for 330 feet. Then a rounded gneiss
of 212 feet other 65 feet of the same crystal
is shown. Then a second rounded gneiss of 446 feet,
followed by 372 feet of the same crystal.
This I assume to be the end of the Oreidae-
Oreadina = 14460 feet.
Over our trails but even if Anthrophyeous some
[illegible]
are several projecting ledges.
There is absolutely not a trace here of Clinton
as said by the Penn. Survey. Here 1685 feet of Clinton
is all of the Red Dalinga series.
