The Paskapoo Slopes are a significant natural, environmental and cultural feature on the western side of Calgary, Alberta. They have a high visual impact and are a prominent landmark along the Trans Canada Highway, Calgary's western gateway from the Rockies. The slopes include a set of six forested benches that were carved by Glacial Lake Calgary during the Pleistocene epoch, and they are incised by a series of twelve ravines. They rise up to 155 metres (510 ft) above the highway along the edge of the Paskapoo Escarpment and the Coach Hill Uplands.
