Have you ever wondered about the different geological formations on Salt Spring? Or how about the various fault lines that run across the island? Maybe you've noticed that digging a hole in the North End will bring up soil and sediment altogether different than from Central or the Deep South End. I've been doing research on earthquakes and tsunamis and came across the free Salt Spring Geology Map some of you may be interested in reviewing. The map and notes have been compiled by Hugh Greenwood, Professor Emeritus, Department of Geological Sciences, The University of British Columbia and is a free download from the Ministry of Energy and Mines.
