Creative Rationale

Over the inland Pacific Northwest near the Cascade Range in Washington or Oregon, where high elevation meets continental air masses, the extremely low pressure creates an atmosphere of dense, archaeological layering. The significant temperature anomaly of 11.6°C drives chaotic marks breaking through structured underlayers, while the moderate humidity allows previous painted gestures to show through like ancient text on scraped parchment. The gentle wind from the southeast adds subtle directional energy to the base layers, creating a composition that feels like years of contemplative reworking in muted mountain light.
