PARDONET BEDS
Definition

The name ‘Pardonet’ has been proposed by McLearn (1940) for the
higher, finer, and darker beds of the Schooler Creek formation. Experience
in recent years has shown that these beds constitute a good, practical
mapping unit from at least Sikanni Chief River to Pine River, and they will
probably be treated in the future as a formation.

The Pardonet beds comprise dark, calcareous shales, dark, calcareous
siltstones, with small proportions of dark limestones, and, rarely, fine,
calcareous sandstones. <A characteristic layer, in places, is a fissile, dark,
calcareous siltstone, which owes its ‘cleavage’ to closely packed and flat-
tened shells of Halobia. The thickness varies from about 250 feet to
possibly more than 2,000 feet, the greatest thicknesses being found in the
more western sections. The contact with the underlying ‘Grey beds’ is
conformable, and in most places gradational, so that it is difficult to choose
the exact plane of demarcation. The contact with the overlying Jurassic
beds of the Fernie group is disconformable.

Pine River Foothills

Very little is known of the Pardonet beds in Pine River Valley. Mon-
otis subcircularis Gabb and ‘Monotis’ n.sp. from near the mouth of Mount-
ain Creek, collected by Williams and Bocock, record the presence of the
upper part of the Pardonet beds. Other collections from Pine River Valley
contain Monotis alaskana var.

Peace River Foothills

A section of the Pardonet beds has been studied by McLearn (1947)
on Pardonet Hill (See Plate V B), on the south side of Peace River, east of
the mouth of Nabesche River (See Figure 9), and, in descending order, is
as follows:
