Survey: by Bill Collis »

Description: OUCC Proc. 7: » “Following the path from the ruin marked on the map as ‘El Trumbo’ one soon finds a steep blind valley drained by a large dry cave entrance. The bedding plane entrance soon becomes wider and then narrower and higher and after a couple of short drops one reaches a loin pitch. The cave changes substantially from here, becoming enormous. A stream rises from the boulder floor and echoes throughout the vast chamber. Then the cave abruptly comes to an end and the stream sumps. There are no significant side passages.

This is a very pleasant cave and, although dry, is very clean. It probably takes a stream from the resurgence up the valley in wet weather. The rock is as smooth as marble and as pretty, though there are few formations. In 1975 the French S.C.A.L. group were found to have explored and surveyed Trumbio in 1964 – comparison of surveys showed substantial agreement.”

Rises at Gueya Reinazo (traced in 1964). Dived in 1985 by NPC » and in 1986 by OUCC ». Neither diver passed a possible slot under unstable boulders.
