Description
Summary:The Coast Range batholith of western Canada and southeastern Alaska, which is a composite of many plutons from a few hundred yards to several miles in cross-sectional width, extends approximately 1,100 miles from the vicinity of Vancouver, British Columbia northwest to Kluane Lake, Yukon Territory. Its width varies from about 40 miles in the north to a maximum of about 120 miles in southern British Columbia. The northern end of the batholith bas not been studied previously in detail. The author traversed this portion of the of the batholith from the northeastern contact at Bennett Lake, British Columbia along the tracks of the White Pass and Yukon Route railroad to Skagway, Alaska and from there by boat along Lynn Canal to Haines, Alaska and the southwestern contact of the batholith. The mapping was done on air photos, whose scale is approximately 1:38,000. The traverse was begun on August 4, 1951 and was finished on August 30, 1951. About four weeks were spent studying thin sections in March and April of 1952. The purpose of this report is to present the results of this study.
