July 22 Monday.
Marble Head.
(8 miles thia)
(Cruss myplan pic) [illegible]
In these strata we saw one grey of interfoliated conglomerate, and another
one(s") of very laminated heddry that reminded much of Cryptogramma
formation. Here then are drawn in beds, with the slighty marvy layers.
As the dip of these old units is the reverse of those of the first seen, and
as they are less crushed and metamorphosed I am convinced that they
are of the Reedman turn, and apparently of the basal Beddeman turn.
[illegible]
The great Post-Ordovician section,
The Beddeman turn is somewhat obscured beyond mile post 401, and the
ground is covered up to about 75-foot above water level by sand and huddle bits
of a former delta of this Hudson when the oceanic level stood more than
100 feet higher than now. It is about ½ mile westward before one sees slaty
dark blue shale.
[illegible]
One then goes past Humbin Mount station to at least mile post
and telesec like
403 in the mud metamorphosed slate and but little quartzite
telegraph dip is to the south, ranging from S 60 W T N 70 W.
gives are to be seen. From about mile post 40½ to Curling (406 miles
[illegible]) we see some grey of quartzite and a particular thick grey joint
underrun with the red slate quarries. In this grey I very clearly huddled orange
dark green
and also with red for many white field bands.
sometimes I saw much of the quartz conglomerate (about half the way) as seen
or covered on July 10 and 11 in the upper part of the marigold series,
then
The thick red shale grey is divided by green shales and gives 9
the next deep slant and I made a more detailed section these strata:
quartzite and they extend for about 1½ miles up to Curling village.
