Fig. 17. — Tokumm Creek and falls at moulh of lower canyon, one-quarter 

 mile above Vermilion River and 3.5 miles (5.6 km.) southwest of Vermilion 

 Pass, British Columbia, Canada. Photograph by Walcott, 1917. 



Tokumm River below the falls has worn a narrow, deep canyon, and in 

 places the canyon walls are so close together and so irregular that the 

 stream cannot be seen from above.
