Evergreen Brick Works

This guide to Evergreen Brick Works in Toronto follows geologist A.P. Coleman, who spent decades studying the layered wall of a working brick quarry in the Don Valley while the Taylor brothers who ran it dug deeper for clay. You'll hear what the stripes in that wall turned out to prove, and how the site kept supplying bricks for buildings like Casa Loma and Massey Hall even as Coleman published his findings. The quarry operated for nearly a century before its clay ran out in the 1980s.
