This lands at the head of a small cascade, at the base of which is a platform overlooking the 36 metres (118 ft) Park Bench Pitch.

[4] The current outlet at the base of Lost Pot is small, but there are a series of abandoned phreatic passages, called the Tate Galleries, 10 metres (33 ft) above the floor of the current outlet, and it is thought that the shafts were formed before the Devensian glaciation, and were originally drained by those passages.

The boulder slope found at the head of the first big pitch was very unstable, and it was necessary to put in a considerable amount of effort into stabilising it before a descent could be made.

[7] Two days later the same boulder slope collapsed whilst a party was at the bottom, severely injuring one member.

The opening of Boxhead Pot in 1995 which entered down the second of the NPC Avens at the top end of Lost Johns' Cave provided relatively easy access to the area.
