Sarah Winkler mimics the process of erosion by applying paint onto wood panels, then sanding back through layer after layer. Oscillating between abstraction and figuration, she pays close attention to borders, boundaries, and edges. Viewers get a sense of the landscape adapting and transitioning, beckoning toward adventure and exploration. As the artist mentions in reference to the title, "[a] magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards. It is located below the vent of a volcano and lava is stored there prior to an eruption."
