Tropical South America 15s 70w

Creative Rationale

Over the high Andes of southern Peru and northern Bolivia, where the atmosphere thins dramatically at extreme altitude, an unusual temperature anomaly creates a stark contrast between the expected frigid conditions and warmer air masses. The significant pressure gradient suggests turbulent atmospheric mixing, while the light winds and moderate humidity create conditions for slow, contemplative weathering processes. This translates into a composition of heavily worked geological layers - like ancient sedimentary deposits scraped and reworked by millennia of wind and temperature cycling, with fragments of earlier painted surfaces emerging through subsequent applications of pigment.
