The Changing Faces of Pompeys Pillar
Stabilizing the Rock
Today, the process of erosion has accelerated swiftly, and now requires stabilization of portions of the rock, including the area containing William Clark's signature. To ensure that Pompeys Pillar survives for future generations to enjoy, geotechnical engineers will assess and make recommendations, after which work will begin on shoring up "the stone bones" of Pompeys Pillar. Unfortunately during this time, we will be unable of offer access to the boardwalk on the Pillar.
However, just because we cannot climb the rock does not mean we cannot experience the same natural wonder that captivated William Clark and has attracted human activity for millennia. Walk around
