INTRODUCTION. 



From Lytton to Vancouver, a distance of 156 miles, 

 (251 km.), the route of the excursion follows the valley 

 of Fraser river. This stream, discovered and explored 

 by Simon Fraser in 1808, is the largest stream in British 

 Columbia whose basin lies entirely within the boundaries 

 of the province. It has a length of 790 miles (1,271 km.) 

 and drains an area of 91,700 square miles (237,686 sq. km.) 

 Rising on the western slope of the Rocky mountains in 

 latitude 53 N., it first flows northward in the great struc- 

 tural valley known as the Rocky Mountain trench until 

 it reaches latitude 54 15' where it bends with a wide 

 curve to the west and then to the south. From Fort 

 George its course is almost due south until it reaches 

 Hope, where, in turning westward, it breaks through 

 the mountains bordering the Pacific coast and within 

 100 miles (161 km.) empties into the Strait of Georgia. 



In its course from Lytton to the sea the Fraser traverses 

 two strongly contrasted types of physiographic form, one 

 the rugged mountainous region of the Coast and Cascade 

 Mountain systems, and the other the comparatively level 

 region of the delta. The former of these two physiographic
