Pillar Arch is located near N.M. 173 just east of the
town of Aztec. The turnoff is halfway between mileposts
5 and 6 where a dirt track heads south about 1/2 mile to
a well site. Pillar, Outcrop, and Alien Arches can all be
seen from the vicinity of the well. Pillar is about 100 yds.
northeast. Outcrop Arch is about 200 yards south, and
Alien Arch is about 1/4 mile southwest.
