Adamana is an unincorporated community in Apache County in the northeast section of the U.S. state of Arizona.

Originally the place was known as Adam Hanna's, as time passed and more people came to visit, the elision of a few letters gave us the name Adamana.

[5] In 1904 John Muir and his daughters, Helen and Wanda, were living at Adamana, Arizona at the Forest Hotel, a large rambling place by the railroad tracks run by a couple who gave guided tours of the Petrified Forest six miles south.

From the hotel Muir would make regular trips to the Blue Forest (now Blue Mesa) making regular trips there alone or accompanied by the girls.

[13] With the combination of all Arizona county precincts into three districts each in 1940, it did not formally appear again on the census.
