Shelter - El Pozo de la Nieve
It's a precious stone shelter. It has 2 " rooms ": in the first one is the well of the snow and in the second one is where you can sleep.
The well has a wooden staircase for the more adventurous.
The second room has a fireplace to warm up at night, although it gets a bit cold through the rocks on the walls (it is easily solved by putting a tarp). Normally the occupants leave wood before leaving for the following mountaineers to come.
