Bogg Hall Rising is the resurgence of both the River Dove and Hutton Beck from their underground courses.
Entry into the flooded cave itself is only suitable for very experienced cavers.
The York Caving Club and North Yorkshire Moors Caving Club also discovered Excalibur Pot, a large cave system nearby. Permits are available for BCA-registered caving clubs.
Excellent stuff, keep up the good work!
