Tropical South America 15s 70w

Creative Rationale

Over the high Andes of Bolivia and Peru, where thin air meets extreme altitude, the atmospheric data reveals a landscape of contradictions—extremely low pressure combined with frigid temperatures and dry conditions, yet with gentle winds that barely stir the rarefied atmosphere. Drawing from Tannahill's practice of layered palimpsests, I've created a composition where fragmented geometric forms emerge and dissolve through translucent veils, with the low pressure manifesting as dense, overlapping shapes that seem to compress and release like memories surfacing through consciousness. The cold temperature anomaly drives a palette of deep purples and blues, while the gentle wind creates subtle, organic undulations that soften the rigid geometry, mimicking how thought patterns shift between structured analysis and intuitive flow.
