Sandstone Shores

The sandstone on Gabriola Island has provided the quarried stone for many buildings in past years.

 

The main rocks exposed on Gabriola's surface are sandstone and shale. Differential erosion of relatively soft shales and relatively hard sandstones helped create cliffs, points, and bays along Gabriola's shoreline. Gabriola and surrounding islands have more than 70 known petroglyphs - sandstone carvings, some of which may be as old as 2,000 years or more.
