Lake valley followed by a syncline on Slate mountain to the west, another anticline on Big Missouri ridge and another syncline along the west slope of the ridge. This is followed to the west by a greatly disturbed anticline and the final westerly dipping limb of the main anticline.

AGE OF HAZELTON GROUP

Fossils were found east of the head of Kitsault river, at two horizons in the basal part of the sediments overlying the Kitsault igneous body. Speci- mens from these localities have been examined by F. H. McLearn who reports as follows:

“The specimens submitted are Gryphaea sp., Oxytoma sp., Belemmtes sp., Rhynchonella sp., and Terebratula sp. The fauna submitted is certainly either Jurassic or Cretaceous and very probably Jurassic.”

Fossils were also collected from two or three horizons close together and near the base of sediments overlying the Bear River igneous body at Divide lake, Bear River district. F. H. McLearn examined them and reports as follows:

“Trigonia sp. No. 1, Trigonia sp. No. 2, Trigonia sp. No. 3. Three are new species of genus Trigonia section undulate.

Belemnites sp., too fragmentary for identification.

Gryphaea sp., too immature to permit specific determination.

Pecten entolium sp., too poor for identification.

Cucullaea sp., probably new species.

The Trigonia specimens suggest but do not prove a Jurassic age.”

Crickmay! has described two new species of Trigonias from Divide lake. He names them Vaugonia veronica and Vaugonia mariajosephinae and dates them as Middle Jurassic.

A fossil was collected from the sediments underlying volcanic rocks of the Bear River igneous body on Kate Ryan creek. The fossil is very poorly preserved and is placed doubtfully by McLearn in the genus Calamo- phyllia. The age suggested is Triassic to Jurassic. An indeterminate fossil was collected from Glacier creek, Bear River district.

COAST RANGE INTRUSIVES

The Coast Range intrusives occupy the western part of Portland Canal area and also form several small stocks in Salmon and Bear Rivers districts. The Coast Range intrusives are hard and resistant compared with the aver- age of the other rocks and, therefore, large bodies of the intrusives. form elevated tracts of country. The granite mountains seen from a distance of several miles are typically light grey in colour and can easily be distin- guished from the mountains of other rocks. The granitic rocks, particularly above timber-line, break off the mountain sides along curving fractures leaving smooth, rounded outlines. On a closer view, from a distance of a mile or less, the granitic rocks are seen to be traversed by numberless cracks giving the rocks a very shattered appearance. Except for roof pendants or
