Land Arts of the American West
Land Arts of the American West is a studio-based field program that seeks to construct an expanded definition of land art through direct experience connecting the full range of human interventions in the landscape—from pre-contact indigenous to contemporary practice. Land art includes everything from constructing a road, to taking a walk, building a monument, and leaving a mark in the sand.
