The Cambrian Shield is a band of rock, primarily consisting of intrusive granite, that extends from North Western Ontario into Northern Quebec and is considered the oldest (inactive) volcano range in the world with the granite having a higher sectional density than any other geostrata in the igneous category...in fact, teepee rats used granite rocks to smash each other's heads open...the best rock band going
