On the north side of the valley and on the strike of the rocks of Pardonet
Hill is Black Bear Ridge!. Only a part of the section on this ridge has been
studied. Dark limestones and siltstones with Monotis subcircularis Gabb
outcrop on the west slope of the ridge, and are underlain farther up the
slope by similar limestones and siltstones with Monotis alaskana Smith var.
These beds are underlain near the crest of the ridge by dark siltstones and
limestones with the Himavatites fauna. At a yet lower horizon down the
south slope are beds with Jwvavites biornatus (McLearn, 1947).

A section of the Pardonet beds has been measured by McLearn (1941)
in a shallow gully on the west slope of the west spur of Brown Hill on the
north side of Peace River, about 10 miles east of Pardonet Hill (See Figure 8).
In descending order, it is as follows:

Compared with the section on Pardonet Hill, that on the west spur of
Brown Hill is, first of all, much thinner. Thick zones of barren siltstones
and fine sandstones are missing. Moreover, the succession of faunas is not
quite the same. However, three faunas are common to both sections: the
Stikinoceras kerri, Himavatites or Monotis alaskana var., and the Monotis
subcircularis faunas. Other faunas occur in one section and not in the
other. The faunal successions of the two sections are, however, probably
complementary, and McLearn (1947) has inferred that the faunal succession

= 1 This ridge is too small to show on the map. It lies north of Pardonet Hill and east of Nabesche
iver.
