The Phallus

The Phallus is a sandstone tower formation in Arches National Park that rises as a vertical shaft of Entrada sandstone. The rock structure stands as a distinct pillar near the park road on the western side of the area.

Geological surveys documented this natural rock formation in the late 1980s as part of comprehensive park studies. The structure itself was shaped by erosion over millions of years, carving the sandstone into its current distinctive form.

Climbers have given this sandstone tower a distinctive name based on its recognizable shape, making it a memorable reference point in the park. The formation has become part of local climbing culture as a notable destination that visitors often mention and identify during their time here.

You can view this formation directly from the park road without needing to leave your vehicle or hike to a separate viewpoint. The roadside access makes it easy to spot and photograph during a drive through the park.

This tower stands next to another rock structure that shares a thematic connection, creating a paired arrangement along the park road. Visitors often discover both formations together during their tour, making the juxtaposition itself part of the experience.
