Slide Mountain Group — Antler Formation

All conodonts from the Antler Formation are from pelitic chert
on Sliding Mountain. They are listed in structural order from
the top in the northeast (NTS N588965 E60154) to the bottom
in the southwest (NTS N588907 E60044). From the age pro-
gression the conodonts suggest that there is a thrust fault dupli-
cating a Permo-Carboniferous sequence.
