Small, steep trib of the Upper Swale with plenty of small drops, fences and a short walled-in gorge containing some siphons near the end. Finishes with Currack Force waterfall which has a very shallow landing in all but spate levels. Thanks to Dave Peel for info.
In high water put-in at road bridge on Stonesdale Lane when driving towards Tan Hill. Also possible to put in from bridleway about 1km further down the valley with a short walk-in. Either take-out above Currack Force or carry on down the Swale where it merges just below Rainby Force (although easy to get out and run Rainby too).
Rainchasers is best experienced as an app.
