Layered sandstone walls curve and flow in dramatic sweeps of light and shadow, their striated surfaces catching bright overhead illumination that carves definition into the undulating rock formations. This black and white photograph captures the sculptural power of slot canyon geology, where erosion has carved sinuous pathways through the earth, creating an almost liquid sense of movement frozen in stone. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
