The country is quite broken along the river, but broad plateaus extend 

 from the breaks both north and south. The hills and valleys along the river 

 are covered with a thick growth of cedar timber. The gypsum beds are cut 

 into by deep canyons, and springs are to be found in all the gulches. The 

 water is all impregnated with gypsum.
