Shelter - Puesto del Morrón de Yeguen
It's not really a shelter, it's a fire watchman's house that occasionally can be open.
Years ago these booths used to be open outside the surveillance season, but lately I usually find them closed. It has already happened on several occasions to find the booths closed and have to improvise a vicac or find a shelter nearby. So I think it's important to never trust that the security booths will be open and have an alternative planned.
