Glacial Grooves, Copley Mountain Lantzville

Many of the local rocky ridges show signs of glaciation from the last Ice Age. The Vancouver Island icecap was as thick as 1,000 feet over 14,000 years ago. It followed the alignment of the Island - roughly Northwest to Southeast which is the exact alignment of the grooves illustrated in the photo. The glaciers were responsible for the rounding of the local ridges, originally formed from molten magma. They were also responsible for depositing the reddish glacial till, worn away from these ridges, with which most of us in Lantzville toil to transform into something capable of growing gardens and holding surface moisture. These deposits form the East Vancouver Island Coastal Plain which does hold water but at deeper levels known as the Quadra Sands Aquifer.
