Illinois-based artist Melissa Pokorny took her camera deep into caves, underwater grottoes, and forest glades in Missouri and Kentucky. But these places were not untouched, they were adapted for tourism, so the pictures are weird: stacks and stacks of red and white chairs extending back into the dark inside a cave, stalagmites all fiery-looking and wet under artificial lights. The snapshots became the basis for even weirder sculptures involving discarded china bought at estate sales, sewing-kit materials, unspecified dried liquids in mid-drip, and armatures that look like rib cages made of scrunched foil. It's Walmart meets field trip meets gross-out. (Platform Gallery, 114 Third Ave S, 323-2808, 11 am–5:30 pm, free)
