 approaches the foothiQs of lava and cuts tluough some of the lower 

 spurs.' These sheets of lava with some interbedded softer rocks have 

 been broken by faults, and the resulting blocks have been tilted up 

 into ridges having abrupt, broken fronts and gradual back slopes. 

 Several such ridges are passed in succession. 



At Preble Humboldt River enters another canyon, which extends 

 through the Hot Springs Range. Just east of Preble, above the 

 upper end of the canyon, may be seen bluffs of black shale with some 

 fractured and iron-stained hmestone. West of Preble the limestone, 

 which is exposed in railroad cuts, is in thick dark-bluish beds ^nth 

 veinlets of white calcite, separated by some thick layers of shale.
