Happy Birthday Petrified Forest! On this day in 1906, President Theodore Roosevelt designated Petrified Forest as a national monument.
Renowned naturalist and author John Muir lived in Adamana, west of the Petrified Forest, in 1905 and 1906. He was an early supporter for the preservation of the park’s petrified wood and is often credited as being instrumental in its designation as a National Monument in 1906. The historic photograph below was taken by John Muir's daughter Helen and is part of the Petrified Forest National Park museum collection. #FindYourPark #npscollections
