Whitesail Lake Map-Area

On Chikamin Range the sedimentary strata are slightly younger in age
and belong to the Middle Bajocian. Fossil collections from these strata
contained numerous belemnite casts and fragments.

Fossil Canyon

The canyon of a small creek flowing into Tahtsa River from the north
about 6 miles below the confluence with Sibola Creek proved to be a very
good locality. The creek cuts across the strata at a slight angle and exposures
are good. The fossils have suffered some deformation from pressure exerted
during folding of the beds and are not generally well preserved, but are
abundant and relatively easy to collect. Collections were made from four
separate localities in the canyon, all within + mile above the mouth of the
creek. In order ascending the creek the collections were as follows:
