Sir William Francis Butler,
The Wild North Land
“ It is true that the cañon valley of the North Thompson lies open, but to follow this outlet, is to face still more imposing obstacles where the Thompson River unites with the Frazer at Lytton, some 250 miles nearer to the south-west; here, along the Frazer, the Cascade Mountains lift their rugged heads, and the river for full sixty miles flows at the bottom of a vast angle cut by nature through the heart of the mountains, whose steep sides rise abruptly from the water’s edge: in many places a wall of rock. ”
