Introduction

the eastern boundary of the Coast Range. He left Houston on the railway
and visited Mount Sweeney and Sibola Peak, examining the mineral claims
there. He also reported on the rocks along Ootsa Lake, Tahtsa River,
Whitesail River, Whitesail Lake, and Eutsuk Lake, refitting himself at
Ootsa for the remainder of his journey to Bella Coola. As a packer on
this trip Galloway hired Barney Mulvaney who was still a prominent char-
acter in the country during the period of the survey. At Ootsa Lake he
hired James Morgan, a pioneer rancher along the lake whose son and
daughter still reside in the district.

In 1920 R. W. Brock, of the Geological Survey of Canada, spent the
summer studying the rocks along Ootsa, Whitesail, and Eutsuk Lakes. In
1924 and 1925 the work of the Geological Survey was continued by J. R.
Marshall who mapped a large part of the area, and in 1935 by M. S. Hedley
who mapped the area north of Tahtsa River to the head of Tahtsa Lake.
In 1945, S. Holland of the British Columbia Department of Mines reported
on the properties in the area. The work on which this report is based
was done during the field seasons of 1947-52.
