Creative Rationale

Over the Altiplano of Bolivia near the border with Chile, at extreme altitude where the atmosphere thins dramatically, this location experiences the characteristic low pressure and temperature anomaly of high mountain terrain. The moderate humidity and gentle northwest wind, combined with the substantial positive temperature anomaly, inspire dense gestural clusters of saturated color that accumulate against luminous atmospheric ground. The dry conditions create breathing room between color passages, while the directional wind energy pulls marks into flowing diagonal movements across the canvas.
