Although the history of Montezuma Castle is pretty well documented, considering that nobody wrote down much of anything when it was a hot spot of ancestral civilization, there’s this one thing that sticks out as a case of mistaken identity. Or make that, mistaken transplantation.

There was a time when Castle Dome City was bigger than Yuma, but those days are long gone. So is most of Castle Dome City.

Fortunately, Allen Armstrong and his wife, Stephanie, are collectors, and what they collect is history in the form of old buildings. As a result, Castle Dome City lives on. In a way.

The Armstrongs have collected and restored more than 20 old buildings that were once part of the Castle Dome Mining District, a former major silver producer. The mining began in 1862 and was productive until 1978, when the last mine closed. The Armstrongs bought what was left of the town and began collecting artifacts that related to mining.

On a hot afternoon in 1849 not far from the Yuma River Crossing, a small party of Army Topographical Engineers came upon a young Indian girl wandering in the desert. She was nearly dead from exposure, hunger and thirst. Many would have left the youngster to her fate. It was a tough, unforgiving land where the strong survived and the weak perished.

The officer in charge was a kind, thoughtful man from Massachusetts, named Amiel Weeks Whipple. He’d only been in the Southwest a short time but had already devel­oped a deep respect for the customs and culture of the native residents.

Whipple shared his canteen with the youngster, then gave her some food. Before she departed he presented her with a small mirror—a simple token of friendship and also something any young lady would surely cherish. She smiled and left to return to her people. Lieutenant Whipple went back to his job—that of surveying a boundary between Yuma and San Diego, marking the new land won in the recent war with Mexico.
