The Albion gravel pit was formed by glaciation, followed by a slow melting process known as kame terracing. As the glacier continues to melt, subglacial streams form beneath the glacier. The streams can flow up and down hills due to pressure caused by the glacier, forming eskers. Also, due to the subglacial streams, delta sediments are deposited. These delta sediments later create delta sands which are the main component of the Albion gravel pit.
