Bleaklow is a high, largely peat covered, gritstone moorland, just north of Kinder Scout, across the Snake Pass (A57), in the Derbyshire High Peak near the town of Glossop. Much of it is nearly 2,000 feet (610 m) above sea level and the shallow bowl of Swains Greave on its eastern side is the source of the River Derwent. Bleaklow Head, marked by a huge cairn of stones, is the high point at the western side of the moor, is a Hewitt and is crossed by the Pennine Way.
