When the town of Amargosa was booming due to the Borax mining business, and its position at the terminus of the Tonopah and Tidewater Railroad, about 350 people lived in the town. The hotel served as a very nice place to stay for both company executives and visiting investors, who were met at the train with white-gloved valets after a long and hot train ride. In addition to the hotel rooms, the cafe and a restaurant within the hotel, other rooms were bunkhouses for workers, an infirmary, a general store and what is now the Opera House, which was mostly used for showing films.
A large gas station and garage across from the cafe was the only location in the area for repairs of trucks hauling borax out of the mines, in addition to passenger car repairs. When the Tonopah and Tidewater Railroad ceased to be economical in 1942, the tracks were torn up completely and sent to Egypt, where the railroad was set up again to aid the Allied military effort in north Africa. Once the railroad stopped, the Opera House, Hotel and about 250 acres of land changed hands many times, until Marta Becket arrived on the scene.
Marta Becket rented the recreation hall in 1967, when it was known as Corkhill Hall; she began repairs, created the sets, and painted murals on the adobe walls. She renamed it the Amargosa, the original name of the former mining town. In 1970, journalists from National Geographic discovered Becket doing a performance at the Amargosa Opera House without an audience. Their profile and another in Life led to an international interest in Becket and her theater. She began performing to visitors from around the world, including such notables as Ray Bradbury and Red Skelton.
In 1974, Becket completed her murals and established the nonprofit Amargosa Opera House, Inc. to continue preservation of the property. Through the Trust for Public Land, the nonprofit bought the town of Death Valley Junction, which was listed in the National Register of Historic Places on December 10, 1981. In 1983, the Opera House bought 120 theater seats from the Boulder City Theater in Boulder City, Nevada to replace the worn garden chairs and the official National Register of Historic Places marker for Death Valley Junction was placed.
