3D visualization of the change of the phase index (PI) due to temperature change in the regolith, at -10 to -100 cm depths on the Ojos del Salado at 5830 m a.s.l. (2012-2018). Scale from blue to light grey representing water (PI=0) to ice (PI=1), the six depressions show the progress of thawing during the six years
