Coming back from the Plym valley, where I failed to make it to Plym Head, the rain stopped and the air cleared for a view off the edge of the moor. Producing the following images. The first two shots include a view of Sheepstor, the second as the main element. It's quite possible that this outcrop will feature in the upcoming film of Warhorse - or they might just plonk a CGI shot of somewhere else.
Although the photos don't quite do it justice, I'd like to assert that the track you can see was literally flowing with water. An extra stream, if another was needed, coming off Dartmoor.
