Pit is today.
At the end of the ice age, the glacier melted, dropping the load of sand, clay, and gravel that it carried. These deposits formed the Colwood Plains, the Coburg Penninsula, and the gravel deposits that are mined to this day in the Western Communities. The Colwood Plains are a large area covering the entire Western Communities where the elevation varies only by 20 metres. As the glacier melted, it broke up and left three monstrous chunks of ice on the Colwood Plains. The sand, gravel, and clay that washed out of the retreating glacier built up around these mountains of ice and formed the shorelines of Florence Lake, Langford Lake, and Glen Lake.
