During Spring 2021, the Club de Montaña y Espeleología La Cambera explored around the Alisas-Los Trillos area, rediscovering some MCP sites and finding new ones. They documented this site in their blog as LC209, describing it as having a shaft top of 30 x 35cm, enlarging about 3 - 4m down. The entrance needs enlarging.
