|Opens May 5||Interpretive Center open 9 a.m. to 6 p.m. daily|
Even when the Monument is closed, visitors may still walk into the site during daylight hours. The walk from the gates to the Pillar is about 3/4 mile. Special arrangements can be made during the off-season for school programs and other special events. Facilities available are the boardwalks, walkways, and vault toilets. All buildings will be closed.
The boardwalk up the Pillar leads to Clark's signature and continues to the top of mesa. It is approximately 1,000 feet long and contains about 200 steps.
Day Use Area
The day use area is ideal for picnicking or relaxing. It is adjacent to the Yellowstone River and shaded by large cottonwood trees.
The interpretive center, restrooms, parking lot and day use area are fully accessible.
Pets must be on a leash at all times.
Natural and Cultural Resources
Please respect our heritage and treat the Monument and its resources with respect. Do not deface any tree, shrub, rock, or ancient Indian artifact. Do not touch petroglyphs or remove any artifact. Not only is this illegal, but it erases evidence of past generations and deprives others of the knowledge about these sites.
Pompeys Pillar Historical Association
The Pompeys Pillar Historical Association provides substantial and much needed support for the Monument. This 200-member, nonprofit organization supplies more than 35 volunteers to assist visitors at the site and to operate the interpretive center. Profits from this enterprise assist with operation of the Monument. More than 2,500 hours of volunteer time are donated each year. For more information about the PPHA, click here.
