Their length does not appear to be more than 1/2 mile
at rest.
All the fossils seen are of either upper Cambrian or
Ordovician age, and I rather think the latter. Of cephalopods
I saw at least three. They are circular in section with the
left side considerably encroached, but none showed the siphuncle
which leads to the line that it may be small. One of the
cells was 1/8 inch in diameter with an excelling of the
surface. As no cells are known in the Cambrian it would
seem that there was here a good development of Ordovician.
These milky white li, are exceedingly scant in fossils.
Among rocks about 4 feet deep that had considerable fossils.
It is possible that a sledge hammer and a chisel well
would yield some good fossils.
Some of these limestone had undergone diagenetic
change in the formation of bipyridal stalactite. This or
creamy becomes silicified and supports laminated algal
growth. But they are anagenic.
