Oakland Geology

Some of Oakland’s busiest places are little visited and little noticed. This set of boulders sits at the intersection of MacArthur and Foothill Boulevards, up by the Eastmont Transit Center.

The stuff of these boulders appears to be the hematite ore of upper Lion Creek. It almost looks like they would fit together in a larger rock.

Who knows how they got here. Somewhere in the city’s maintenance yards there must be a stockpile of Oakland boulders, kept handy for deployments like this where you want to keep cars off the dirt and on the road.
