Creative Rationale

Over the Columbia River Plateau in eastern Washington State, where dry continental air meets the volcanic landscape of the Cascade foothills, extreme atmospheric conditions create a stark and energetic composition. The exceptionally low pressure drives heavy accumulations of saturated color toward the canvas edges, while the moderate wind from the north-northeast sends gestural splatters and organic forms radiating outward from concentrated pools. The frigid temperature and bone-dry humidity manifest as muted earth tones punctuated by icy blue accents, with expansive luminous white space breathing through the center like the high desert's crystalline winter air.
