Found the following article online, use it to answer the question: What is the name of the obelisk whose first part would be 40 ft² square and 10 feet high?

The first part of the obelisk would be 40 ft² (12 m²) square and 10 feet (3 m) high. It then would reduce to 32 ft² (9 m²) square and rise 35 feet (11 m). The next segment would be 22 ft² (6 m²) and would rise 85 feet (26 m) to become 6 ft² (1.8 m²) at the top. The total height would be 130 feet (40 m). In the pedestal there would be 300 ft² (91 m²) of floor space. Harvey's books, explaining 20th-century civilization, as well as a world globe, a bible, encyclopedias, and newspapers, were to be placed inside two vaults and hermetically sealed in glass. Harvey also wanted to place in this large room: "numerous small items now used in domestic and industrial life, from the size of a needle and safety pin up to a Victrola." It was estimated that the construction would use 16,000 bags of cement, 30,000 ft³ (850 m³) of sand, 58,000 ft³ (1,642 m³) of gravel, and tons of corrugated steel reinforcement. The Portland Cement Association donated the service of one of its experts, who pronounced that the Pyramid would not deteriorate or suffer from erosion and would last for over a million years. To prevent water in the valley from interfering with the foundation and to shore up the low knoll to support the heavy Pyramid, Harvey constructed a 165 feet (50 m) long retaining wall of stone and concrete.He also built a roughly semi-circular, terraced amphitheater at the foundation of the Pyramid which he called the "foyer". He intended to rent this out and use the revenue for the pyramid project. The land for the amphitheater was first dug in late 1923, and construction continued off and on for the next five years whenever financing, building materials, and labor were available. Unlike other Monte Ne building projects designed by architect A. O. Clark, the amphitheater apparently had no architectural input and was not built according to blueprints or a single design. Those who worked with Harvey noted that he seemed to just "work it out in his mind from day to day". The result was a unique structure, irregular in formation,...
