Over the Bolivian Altiplano near the Chilean border, this high-altitude location experiences extreme low pressure at 623.0 hPa with a massive pressure gradient of 351.71 hPa/cell, creating atmospheric turbulence that translates into dense archaeological layers of paint scraped and reworked. The significant temperature anomaly of 11.3°C above the zonal mean drives chaotic gestural marks breaking through more structured underlying layers, while the moderate humidity of 63% allows previous painting sessions to show through with translucent, palimpsest-like visibility. Light winds from the north create subtle directional energy in the foundational marks, suggesting years of contemplative reworking in this thin mountain air.
