 Harvey moved his office to his cottage next to the amphitheater, as work continued on the Pyramid. In January 1929, Harvey along with Lowell and H.L. Hardin of Kansas City incorporated the project creating The Pyramid Association. The association was to fulfill Harvey's Pyramid plans in the event of his death. The estimated cost of the Pyramid itself was $ 75,000, but Harvey exhausted his funds on construction of the amphitheater. The stock market crash of 1929 ended all construction. In a last-ditch effort to save the project, Harvey sent letters to wealthy men asking for funds to complete the project. In his letters he explained that civilization was dying and that only rich men, like the intended readers, could save it, if they could send money for his pyramid. Despite the fact that Harvey claimed his correspondence was "the most important letter ever written" he received no replies and the pyramid was never built. All that remains of the project is a retaining wall and the amphitheater that are under the waters of Beaver Lake most of the time.
