Petrified Forest National Park (Rainbow Forest)

Navajo County, AZ

Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.

South-unit visitor hub of Petrified Forest National Park — the Rainbow Forest Museum anchors short walks among giant Triassic-age (Chinle Formation) silicified logs, the Giant Logs Trail, Long Logs, and Agate House. The park also spans Painted Desert badlands to the north; this pin marks the primary south-entrance geology stop rather than a park centroid.
