Yesterday we came across an interesting and unusual feature that we've never encountered before in mountains (outside of Kamchatka in 2013). A deep crack/crevice was found near the summit of Morron de Enmedio at 1098m in the Sierra Elvira. Coming up out of the crack was a constant strong blast of warm wind. This feature (the Raja Santa cavity) is just west of the summit if you want to experience this for yourselves. Natural warming for a cold winters day!
