A cliff of gabbro extends along the east side 
of the road, while, on the west side are black- 
weathering gneisses of doubtful origin cut by 
pegmatite veins. These veins do not cut the 
gabbro on the east side of the road. 
Thin-banded gneisses on both sides of the 
road have small areas of limestone associated 
with them. To the left of the road they are 
cut by a 40-foot (12-2 m.) diabase dyke be- 
longing to the youngest series. 
The cliff to the right of the road is composed of 
well banded gneisses cut by pegmatite dykes. 
Some of the gneisses appear to be altered 
sediments. One of these gneisses at the south 
end of the hill has been prospected for graphite, 
of which it contains a little. Another prospect 
in the face of the hill shows ore connected with 
a dyke of gabbro, very similar in appearance 
to that found at the Dominion mine. Imme- 
diately beyond the next small creek, rises a 
hill, faced towards the road with Grenville 
limestone. On the top of this hill is an old 
prospect, where columnar graphite occurs at 
the contact of pegmatite and Grenville lime 
stone. 
For three-fourths of a mile (1-2 km.) north 
of this, black-weathering gneisses, mainly of 
igneous origin, and much cut by pegmatites, 
which also weather black, are exposed on either 
hand. 
The hill on the west side of the road consists of 
granite gneiss at the southern end, becoming 
dioritic toward the north. Across the road are 
gneisses, similar to the hypersthene-granite- 
gneisses at the Emerald mine and containing 
the same garnetiferous bands. 
Leda clay with its capping of Saxicava 
sand, extends from here to the Emerald mine.
