Entertainment Value: II
Four small slip rifts in a disused quarry on the edge of the Hambleton escarpment.
These rifts lie in an abandoned quarry, and are best approached from the public footpath at the head of the escarpment.
Obvious tube entrance just above quarry floor.
A short crawl to junction with high rift, right for 10m leads to boulder chokes, left for 2m and up 4m leads to visual connection with Boltby 2. Straight on leads to a series of parallel rifts all ending in chokes or becoming to tight.
A few metres north of 1, and 3m up, a very tight passage turns right into a roomer crawl ending in a choke with a visual connection with 1.
Further north along the face, just beyond a step in the quarry floor.
A very tight squeeze down pitch (handline useful for return) into a rift ending in boulder ruckles.
Ruckle at Southern end has a number of inviting black spaces and a dig here would be rewarding.
STONE LEVER POT (BOLTBY IV)
On the same tier as 3 but 10m West.
Entrance covered with wood (replace). Squeeze under slab and over pit, continuing rift ends in boulder choke after 10m but chinks of blackness can be seen beyond, a dig here might gain a continuation. Down the pit and heading South (back under entrance), a small phreatic tube can be entered with vocal link to the surface.
