Where This Rock Comes From.
The material in our pit didn't form here. It traveled here from north of Stuart Lake during the Wisconsin Glaciation period, carried by the Cordilleran Ice Sheet.
The glacier moved south and eventually stalled in the hills south of Prince George. When it stopped moving, all that material it had been carrying got deposited in one place. That's our pit.
Because it stopped here — rather than being ground up and mixed with local material — the rock retained its glacial properties. It's harder, denser, and completely clay-free. Clay causes frost heave and instability in road base. Our rock doesn't have it.
The glacier was almost 65 feet deep at this location, which is why our pit runs 65 feet deep before the rock quality changes. That depth gives us years of consistent, specification-grade material.
