According to the Mojave Desert Dictionary:
The Sam Houston No. 1 Mine: A silver mine in the Calico Mountains that was discovered by Hugh Stevens and sold to a Mr. Johnson, who then sold it to two Frenchmen for $40,000. They changed the name to Blackfoot Consolidated No.1 Mine.
Then, oddly enough:
The Sam Houston No. 2 Mine: A silver mine in the Calico Mountains that was discovered by Hugh Stevens and sold to a Mr. Johnson, who then sold it to two Frenchmen for $40,000. They changed the name to Blackfoot Consolidated No.2 Mine.
And to further complicate matters …
The Sam Houston No. 3 Mine: A silver mine in the Calico Mountains that was discovered by Hugh Stevens and sold to a Mr. Johnson, who then sold it to two Frenchmen for $40,000. They changed the name to Blackfoot Consolidated No.3 Mine.
Mysterious, or what?
