   The back wall with the trees over the entrance has collapsed into the hole leaving a brown stain on the wall and making the initial descent more tricky. (More recent pictures of the entrance were originally attached to nearby site 0382 in error.)
   A 7m entrance pitch lands in a walk down to a rift and then a descent through boulders on the left hand side to emerge at the head of a slope into a large passage. This continues in the same direction as the first rift, via two side steps, up and over various obstacles and past some good decorations and interesting holes up in the roof. After a 90° turn, the cave ends in some chambers, again with lots of formations. There are many calcite flowers and the floors are decorated and largely undisturbed. Worth a visit with a camera.
The entrance is / was marked M17 with green paint.
