TOPOGRAPHY. 



OROGRAPHIC FEATURES. 



The area discussed consists of a vast body of Archean gneisses and similar rocks 

 carrying on its flanks upturned strata of Paleozoic and Mesozoic ages. In some 

 localities outflows of lava rest upon the older rocks. In the northeast corner it also 

 includes a low, terraced, undisturbed limestone area, which now constitutes a rolling 

 foothill region. During Pleistocene times the uplift was covered with a great glacier 

 which, moving in various directions, but chiefly west and north, sculptured and 

 fashioned the regioii much as we now find it.
