It may be thought odd that the river should

 granite, and porphyry, red rustings of iron, red 

 grits of carnelian, agate and garnet. All the 

 tributaries come bearing their tokens of red 

 copper, and with the rains the whole red sur- 

 face of the watershed apparently washes into 

 the smaller creeks and thus into the valleys.
