There is a parking area near the entrance of the park, where you can see a great view of the mountains and lake. A plaque contains information on Mount Meikle and the basin below it that filled with water creating Gwillim Lake. As the information indicates "Two hundred million years ago, it was covered by a shallow open sea. Skeletal remains of marine life fell to the sea floor, gradullay forming thick brittle beds of limestone and dolomite". The sea bed is now three kilometres below the surface where this sign is posted. Gwillim Lake Provincial Park BC
