It was founded fifty miles (80.5 km) southeast of Ajo, c. 1880.
By 1886, the post office closed and the town has been abandoned since.
The town was near Quijotoa, Allen is on the western side of the Ben Nevis Mountain and Quijotoa is on the east.
When American settlers began flocking to Quijotoa, General Brackett was among them who decided he wanted to build a hotel.
The small settlement had the hotel, a half dozen houses, a few tents and a post office established in 1880.
