Trafalgar Mosaic

The Trafalgar Moraine is a geological landform straddling Oakville and Milton in Ontario, Canada. A small portion of the moraine extends into Burlington at Milton's southern border. It is a subtler topological feature than the better-known Oak Ridges Moraine, primarily because it was formed as an end moraine at the terminus of a glacial ice sheet, instead of between two retreating ice lobes (known as interlobate). The ice sheet pushed material to form the ridge, which is composed of Halton Till sediment, rich in silt and clay. By contrast, the Oak Ridges Moraine is primarily sand and gravel. The ridge was probably formed during a pause in the retreat of the ice sheet. The moraine covers an area of 892.5 hectares of primarily private land, though a small portion is public.
