Given these setbacks, and Harvey's belief that civilization was doomed, he began to focus his efforts on building "The Pyramid", a 130 foot tall obelisk that would eventually contain books and objects that reflected human life in the 20th century, preserving them for future generations to discover.

Some of the resort buildings were repurposed and continued to be used on and off until the 1960s, when the United States Army Corps of Engineers began construction of a dam on the White River, creating Beaver Lake.

This tower was demolished in February 2023 by the Corps of Engineers, citing ongoing vandalism and health hazards posed by the deteriorating structure.

[5] In 1900 he purchased land near a small village called Silver Springs, and renamed the area "Monte Ne", which he claimed were the Spanish and Native American names for "mountain" and "water".

[5] In December 1900, with $52,000 of individual investors' money and $48,000 of his own, Harvey formed the Monte Ne Investment Company, which held the deeds to all of the land.

The Arkansas Railroad Commission granted a charter on April 26, 1902, and the Monte Ne Railway Company was incorporated the following month with a capital stock of $250,000.

Harvey purchased an engine, a tender, and a passenger coach from the Frisco Railroad and built a large log depot along the bank of the lake at Monte Ne.

In April 1904 the Monte Ne Club House Hotel and Cottage Company was organized with $250,000 in capital and with Clarke as both the chief architect and superintendent.

During this period of construction Harvey was very concerned about the financial situation at the resort, writing to his wife "I am trying to save the ship from sinking".

Monte Ne's small downtown area had at one time a general store, a livery stable, a gristmill, and a post office.

[14] To help attract tourists, Harvey often brought in musicians and hosted dances and other events to give Monte Ne a constant festive atmosphere.

In 1913 Harvey spearheaded the founding of The Ozark Trails Association (OTA) to promote marking and building (but not financing) quality highways.

Not surprisingly, his interest was in bringing people to Monte Ne, as he stated: "My personal interest in the Ozark Trails is that they all lead to Monte Ne", though he said further "My inclination runs toward doing something of a progressive nature that will promote the collective good, and I have now concentrated all that inclination on carrying out the system of roads known as the Ozark Trails".

Interest in the group began to waver noticeably when Harvey finally stepped down as president at a 1920 convention in Pittsburg, Kansas, that was attended by only 200 delegates.

Therefore, the U.S. Bureau of Public Roads (BPR) changed all the roadways' names to uniform numbers, despite fierce protest from the OTA.

In February 1920, he published Common Sense, in which Harvey announced his intention to leave a message for the future in the form of a pyramid.

Figuring that the mountains were approximately 240 ft (73 m) high, Harvey planned to construct a massive concrete obelisk, and its capstone would remain above the debris.

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".

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.

Following the Egyptian mania that gripped the country after the discovery of King Tut's tomb in 1922, Harvey's Pyramid project sparked a lot of interest and was widely reported throughout the U.S. Tens of thousands of people came to Monte Ne during the 1920s to see its progress, and 20,000 visitors were recorded in a four-month period in 1928 alone.

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.

As Harvey's interests shifted to the Pyramid, Monte Ne's resort days effectively ended and the number of visitors slowly dwindled.

Harvey prepared with railroad excursion rates, media facilities, upgraded roads, and food concessions, anticipating 10,000 delegates.

The courts decided that the property that was still deeded to the Pyramid foundation belonged to his widow, May, who sold it before moving to Springfield, Missouri, never to return.

[21] In 1955 a Springdale, Arkansas antiques dealer named Dallas Barrack converted the Club House Hotel into the "Palace Art Galleries".

Today, the tomb sits on private property visible from the Monte Ne boat launch on Beaver Lake.

The lake dropped to its lowest level on January 22, 1977, more than 27 feet (8 m) below its average depth, and the amphitheater and bridges were visible for the first time in more than 10 years.

[25] A portion of the original log section Oklahoma Row was removed prior to the flooding and was situated just north of Monte Ne on the east side of Highway 94.
