An interesting cold hole at the lower end of a blind valley above Los Boyones (117), the main resurgence in Secadura. A small rift in the floor is choked; a small chamber above this also appears to be choked.
The GPS taken at Easter 2013 is ETRS89: 30T 455330 4799307, probably putting it in the "wrong place".
