Shallow ground temperature measurements on the highest volcano of the Earth, the Mt. Ojos del Salado, Arid Andes, Chile
The Mt. Ojos del Salado (6893 m a.s.l.) is situated within the Andean Arid Diagonal, on the Chilean-Argentinean border. Due to the extremely arid climate, surface ice is not widespread on the Mt. Ojos del Salado and at similar high altitude massifs in the region, though ice-bearing permafrost might...
