There are least 79 named Pillars in Wyoming according to the U.S. Geological Survey, U.S. Board of Geological Names. A Pillar is defined as a "vertical, standing, often spire-shaped, natural rock formation (chimney, monument, pinnacle, pohaku, rock tower)".^[1] The Oxford Dictionary of Geography defines Earth Pillar as "an upstanding, free column of soil that has been sheltered from erosion by a natural cap of stone on the top". They are common where boulder-rich moraines have been subject to gully erosion, as in parts of the southern Tyrol.^[2]
