Description

Morphology

A small step places us at a base where a short crawl begins.

Progression

A small step places us at a base where a short crawl begins; curiously the access to the crawl had been blocked with a wall of stones.

History

Cavity located and explored by Juli Serrano on 11 February 2021; it seems to have been unblocked and partially blocked again previously, but we do not know the reason or the authors.
