Cathedral Formation
1. Massive bedded, arenaceous, siliceous limestone 60 ft.
2. Massive bedded, arenaceous, siliceous dolomitic limestone. At 495 feet from the base the beds are thinner and of a dark gray color for 30 to 40 feet. At 825 feet the massive layers are banded with light and dark grey colors 1560 ft.
Owing to small step faults the thickness of this series of strata is uncertain. The entire thickness on the northeast side was measured and an allowance made for duplication by faulting.
This great limestone series forms bold, high cliffs on the east face of Mount Stephen and the west side of Cathedral Mountain.
