Creative Rationale

Over the rugged Cascade Mountains of Washington State, where elevation meets atmospheric turbulence, an extraordinary cold anomaly creates a dramatic temperature inversion. The moderate northwest wind carries moisture across the peaks while exceptionally low pressure creates sparse, dry conditions with minimal humidity. This stark, high-altitude environment inspires a Francis-like composition where icy blues and muted earth tones pool at the canvas edges, driven outward by wind energy, while the central space breathes with luminous negative area reflecting the thin, crystalline mountain air.
