Grey limestone, top of ‘Grey beds’?

If the grey limestone on the axis of the anticline at this locality is the
top of the ‘Grey beds’, the thickness of the Pardonet beds here is about 160
feet. The top beds, the Monotis subcircularis beds, appear to be absent
here as on Pink Mountain. The highest five zones in the above section,
comprising 51 feet, are evidently of the Himavatites-Monotis alaskana var.
zone. ‘The sixth zone from the top, the 7 feet of limestone and siltstone,
appears to be of the H. cf. dilatata or Cyrtopleurites cf. bicrenatus zone,
which underlies the Himavatites zone in the section on the west spur of
Brown Hill in the Peace River Foothills. The remaining and lower part
of the section below Chicken Creek probably belongs somewhere between
the Stikinoceras kerri and ‘Styrites’ creneanus zones on Pardonet Hill, or
embraces them all; no zonal fossils are present, however.

The Pardonet beds can also be recognized about 10 miles farther west
on the south side of Sikanni Chief Valley, high on the west slope of Mount
Hage (See Plate [V A). The section is thicker and has fewer fossils than
below Chicken Creek. It has been measured by McLearn (1946A) and,
in descending order, is as follows:

Limestone and calcareous sandstone of ‘Grey beds’?

The thickness of the Pardonet beds here is about 400 feet, a considerable
increase over the thickness in the more eastern section below Chicken Creek.
The uppermost 15 feet is of the Monolis subcircularis zone, apparently
absent below Chicken Creek. The 25-foot section below the M. sub-
circularis beds is a part at least of the MZ. alaskana var. or Himavatites
zone, although Himavatites is not present here. Other and lower zones
cannot be identified in this section.
