Creative Rationale
Over the inland Pacific Northwest near the Columbia River plateau in Washington state, this location experiences extremely low atmospheric pressure with a steep gradient, moderate easterly winds, and frigid temperatures well below the regional average. The harsh cold drives me toward Riley's early black-and-white optical works, while the moderate wind speed creates medium-frequency undulations that flow horizontally across the canvas. The steep pressure gradient demands tightly packed parallel lines that create an intense vibrating effect through precise mathematical spacing.
