BCER dam and local geology

After a long wait Geoscan finally placed online the text from J.A. Roddicks, geological survey of the area, published in 1965. This was the first thorough geology survey of the area.
Vancouver North, Coquitlam, and Pitt Lake map Areas, British Columbia With Special Emphasis On the Evolution of the Plutonic Rocks.

Yikes !!! a 200Mb PDF zip download, but it includes the three maps and three figures. A complete package.

a Lidgerwood cable system was setup at Coquitlam dam, probably also used at Buntzen Lake they were also more commonly used in the logging industry. One of the HUGE blocks is still near the dam hidden in the forest.
