BUI.I.ETIX 707 PLATE XXVI 



SILVER CASCADE. 



When this photograph was taken but little water was flowing over the rocks, but earlier in the 

 season, when the snow on the mountain is melting, the water leaps from ledge to ledge and 

 slides down the rocky slopes in sheets of lacy foam. The smooth, round slopes and mountain 

 tops show clearly how readily the most massive granite softens and decays. Photograph 

 by L. C. McClure, Denver; furnished by the Cripple Creek Short Line.
