According to Gladwell Richardson, the author of the book "Story of Two Guns and Canyon Diablo, Arizona", during the winter of 1879-80, Billy the Kid and his outlaw gang hid in the ruins of a stone house and corral on the west rim of Canyon Diablo, across from Two Guns.

Various homesteaders and pioneers staked claims to the area.
In 1912, the National Old Trails Road, also known as the "Ocean-to-Ocean Highway", was established.
It became part of the National Auto Trail system in the United States and stretched from Baltimore, Maryland to California.
The road ran through Canyon Lodge (Two Guns).

In 1914, Arizona State engineer Lamar Cobb selected and surveyed the Two Guns location for the construction of a bridge across Canyon Diablo.
Thomas Haddock of Williams, Arizona was granted the contract to build the bridge.
He used concrete and reinforcing steel supplied by the state to erect the bridge.
On March 17, 1915, Canyon Diablo Bridge opened to traffic.
The bridge was part of the National Old Trails Road.

In the 1920s, Earle and Louise Cundiff purchased at least up to 320 acres of the land.
The Cundiff's established a gas station and eatery at Canyon Lodge which became a busy stop for those who traveled to the west coast.
Henry "Two Gun" Miller became interested in the possibility of establishing a business in the area and leased some land from the Cundiff's.
Miller established a zoo with mountain lions and other desert animals.
He also built a store on top of the Apache Death Cave and sold the skeletal remains of the Apaches to tourists.
The National Old Trails Road became part of U.S. Route 66 in 1926 and the flourishing town was officially renamed "Two Guns".

On March 3, 1926, Miller got into a dispute with Earle Cundiff over his lease and then shot and killed Cundiff.
Miller did not go to prison because he was acquitted of murder during his trial.
When Miller returned to Two Guns he was mauled by two mountain lions and was bitten by a poisonous gila dragon and became ill.
He soon left Two Guns and never returned.
