Avenc Estella

A door gives access to a small 2-metre-deep shaft, which with caution can be descended without a rope. Once inside, we will descend a 2-metre drop in a N direction, and reach a small chamber with lithogenic formations. We will descend 3 metres more down a ramp with a 0.40x0.50 metre crawlway that leads to a small chamber similar to the previous one. The deepest point is reached by descending through a crawlway and a 2-metre drop and continuing along a ramp full of fallen rocks that block the way. To go to the other side of the cavity, it is better to descend through the crawlway at floor level in the first small chamber, where we will find the widest and highest room of the pit; this communicates with the entrance shaft in its upper part, but with more difficult access. At floor level there is a possible continuation through a crawlway blocked by mud and stones that have fallen from the entrance. We will continue in a S direction, going up the ramp of mud and stones, passing towards another longer and steeper room with a lot of mud. At the end it climbs 2 metres but with no possibility of continuation.
