In 1906, John Huddleston, the local farmer who owned this property, found the first diamonds here in Murfreesboro, AR, and started the diamond mining rush. After a series of ill-fated mining ventures followed by tourist attractions, the site became an Arkansas state park in 1972. Visitors today are invited to prospect in the park's diamond search area, a 37-acre plowed field that is the eroded surface of an ancient volcanic pipe that, 95 million years ago, brought to the surface the diamonds and some of the semiprecious stones lucky visitors find here today. Within the park boundary many remnants of old mining ventures remain including the Mine Shaft Building, the Guard House, mining plant foundations, old mining equipment, and smaller artifacts. Nowhere else is North American diamond mining history as evident or as well-preserved as here.

The site offers short films, exhibits, tours, educational programs, and occasional recreational and educational events.

The Birthplace serves as a showplace for reproductions of the works of one of America's foremost portrait painters and as an authentically restored and furnished workingman's home and the site of the first snuff mill in America. The wooded homestead on the banks of the Mattatuxet Brook also features a partially restored grist mill and a fish ladder. In spring the ladder is packed with migrating herring, swimming furiously to reach the pond above the mill dam. The grist mill houses the original fine-grained granite stones used to grind corn for the famous Rhode Island Johnny Cakes.

Visitors to the Museum discover the people and machines that have moved North Carolina. Located on the site of Southern Railway's former steam locomotive repair facility Spencer Shops, this is where locomotives that hauled Southern's passenger trains and freight trains filled with North Carolina furniture, textiles, tobacco, and produce were serviced from 1896 to the late 1970s. Up to 3,000 people once worked here but today visitors can see an authentic train depot, antique automobiles, and a roundhouse with 25 locomotives.
