Section 25, NE end of Dugout Mt Ridge, measured
N220E from tin shack, dip here is variable
but between 15°+30° to the NNE in the wrygamy
Conglomerate.
1) Covered, probably gaptank.
2) Calcandite, lowest certain bedrock exposure,
much sand (brown) and chert pebbles,
at least 140' thick, probably about 160'
including changeasy dip and covered base.
Coll. 8/5/57/10 (2 tags) at about
110'
3) Covered, 12', perhaps Conglo, may be nat.
4) Conglo, chert quality to increase over ts.
brown sande more apparent.
/5' Coll. 8/5/57/11
5) Conglo and covered intervals, this is
down a dip slope with a number of
folds and faults. I estimate the
thickness of Conglo here to be 150'.
The upper beds become more calcic and the
amount of organic frag increases greatly.
a few beds are carboniferous and some
are sandstones(?) and white silts.
These form a transition in the upper 40'
into the next period.
