 The Loon Lake mountain fault-block, as viewed from a point three- 

 fourths of a mile to the south-southwest. On the left (west) side the steep 

 slope is that scarp of the larger of the two Schroon lake faults. The 

 down-tilt of the block toward the east is perfectly shown. The cliff, 

 several hundred feet high, which faces the south, is the scarp of the fault 

 along the south side of the mountain. The upper portion of this mountain, 

 which rises 600 feet above the valley, consists of Grenville quartzite and its 

 lower portion of biotite-garnet gneiss.
