This was a previously unrecorded location noticed on the return journey (see Logbook date 6/8/2024) . A 20m diameter, 10m deep doline filled with hazel trees. Stones dropped at the west end of the doline suggest a pitch. A rope was needed to safely access the doline floor. This feature is c. 100m from the main track, so might be worth another look.
