heaps at their bases. The slopes have been trenched and fur- 
rowed by running water derived from the melting ice and snows. 
The scarred and shattered surface everywhere testifies to the 
great rapidity of frost action. The results of glaciation are con- 
spicuous over all its parts, attesting the fact that the ice-cap has 
over-ridden its entire surface at some previous time. Remnants 
of local glaciers still exist among the higher peaks of its north- 
ern border. Bowlders are abundant, while the paucity of till is 
quite marked. 
Owing to much variation in texture, the intimate relation- 
ship of rock structure to topography is well marked, as shown in 
the case of the dikes of basic rock —diabase (?) — found cutting 
the gneiss in various directions. The gneiss has been intricately 
folded and contorted. 
LAKE CLASSIFICATION 
No large lakes are found on the peninsula. The basins vary 
in size from one and a half miles in length down to the merest
