I just finished reading “Vanished Arizona” by Martha Summerhayes which is fascinating. A diary of her time as an Army Wife (1874-1908). She spent considerable time in AZ and I couldn’t stop reading. Free on the Gutenberg Project (I’m sure there are other free downloads also). This does mentions the Army and Indian HEADS. Fascinating history of the Colorado steamers and HOW these soldiers and families had to live in the outposts/desert.
