Glacial surveys were made to determine the rate of recession or advance of the glaciers for streamflow investigations. Methods consist of setting up fixed reference marks near the toe of a glacial tongue. Annual measurements of the distance from the nearest point of the forefoot to a reference point, taking annual photographs, and trigonometric measurements of markers set out on the ice. Survey results are indicated for glaciers of Garibaldi Park, Franklin Glacier and glaciers of the Selkirk mountain Range. It is concluded that the rate of recession is not governed entirely by weather. Valley conditions and the steepness of the slope have a marked effect. The glaciers were in a stable condition until 1890, when a general recession began.
