Hart Side

Hart Side (the hill side frequented by harts) is a subsidiary top on one of the east ridges of Stybarrow Dodd, which is a mountain (or fell) in the English Lake District, west of Ullswater on the main Helvellyn ridge in the Eastern Fells. With a height of 2,480 feet (760 m) Hart Side rises above the col separating it from Green Side by 75 feet (23 m). Some guide-book writers have treated Hart Side as a distinct fell, and have devoted a separate chapter to it.

The same writers have treated the lower Watermillock Common as part of (or associated with) the fell. Other writers have simply focussed on routes to and between the many individual tops here and throughout Lakeland.

Hart Side and Green Side are the two ends of a ridge which is composed of andesite rock, a sequence of lava flows from ancient volcanoes. A lead vein in the Green Side end of the ridge was exploited by the most successful lead mine in the Lake District until it closed in 1962.
