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.

Plumas-Eureka State Park provides visitors with a glimpse into a fascinating period of California history, as well as opportunities for quiet recreation in a high Sierra mountain setting. The focal point of the park is the museum building and historic area surrounding it. Originally constructed as the miner's bunkhouse, the museum now serves as a visitor center. Inside, displays depict the natural and cultural history of the park. Outside and across the street from the museum is the historic mining area, where the Mohawk Stamp Mill, Bushman five-stamp mill, stable, mine office, Moriarity House (historic miner’s residence), and the blacksmith shop depict life in gold rush-era California.

The park offers exhibits, tours, and demonstrations.

There is still gold in the foothills of the Sierra Nevada, at the California State Mining and Mineral Museum, in historic Mariposa. This is where explorers John C. Fremont and Kit Carson found the rich Mariposa Vein and opened the first mill to crush ore and extract gold in California. Visitors can discover for themselves California's mineral wealth, colorful history, and geologic diversity as they view the official mineral collection of the state of California. The collection, which began in 1880, contains over 13,000 objects including mining artifacts, rare specimens of crystalline gold in its many forms, as well as beautiful gem and mineral specimens from California and around the world. The museum displays the Fricot "Nugget," a rare specimen of crystallized gold discovered in the American River in 1864. This 13.8-pound specimen is the largest remaining intact mass of crystalline gold from 19th-century California, when these finds were more common but usually were simply melted down. Visitors can also take a trip back in time as they walk through a mine tunnel and see how gold was mined in the mid-1800s, when California was a wilderness, being transformed by rapid development. The museum's assay office and working scale model of a stamp mill will help visitors discover how gold was found and extracted from the rocks.

The museum offers exhibits, tours, educational programs, and educational and recreational events.

"The museum building is one of the oldest surviving buildings in Van Horn. When Culberson County was first created (it broke off from El Paso County), the Museum site served as the first courthouse while one was being constructed. It subsequently served as a hotel for more than four decades. It was purchased in 1979 by the Museum Association and has been in the process of restoration since that time.

The Museum contains a large quantity of artifacts reflecting the history of Van Horn and the surrounding area. It features an old western style saloon with bar and mirrored back bar which have been in the same room since the early 1900’s. There are displays showing the history of mining, ranching, the railroad, and other early activities, as well as personal items which belonged to members of early pioneer families who first settled here."

"The earliest evidence of humans along Turnagain Arm is at Beluga Point, which prehistoric hunters used as a view point to search for Beluga whales and sheep. The first white explorers arrived in 1778 aboard Captain Cook's ships, Discovery and Resolution. Cook sailed up Cook Inlet hoping to find the Northwest Passage, but had to "turn again", leading him to name the water body River Turnagain. In the late 19th century, miners and trappers began traveling into interior Alaska from Whittier and Seward along old trails that soon became established routes with roadhouses. In 1895 prospectors crossed from the south side of Turnagain Arm to the north and searched for gold from Girdwood to Rainbow Creek.

In 1903, the Alaska Central Railway began building a railroad from Seward to Fairbanks, but the company soon went bankrupt. The U.S. Government bought the railroad in 1915 and improved the trail along the arm to handle the horse and wagon traffic needed for railroad construction. The trail was also used to deliver mail between Anchorage and Seward. IN 1917 telegraph lines were laid along the Turnagain "road" and by 1918 the railroad extended from Seward to Anchorage, with flag stops at Bird Creek, Indian, Rainbow and Potter. Remnants of construction camps remain along the trail, but are barely discernible. Part of the original trail was covered by the highway which was completed in 1950 and paved in 1954."

Cornwall Furnace is a unique survivor of the early American iron industry. Originally built by Peter Grubb in 1742, the furnace underwent extensive renovations in 1856–57 under its subsequent owners, the Coleman family, and closed in 1883. It is this mid-19th-century ironmaking complex which survives today. At Cornwall, furnace, blast equipment, and related buildings still stand as they did over a century ago. Here visitors can explore the rambling Gothic Revival buildings where cannons, stoves, and pig iron were cast, and where men labored day and night to satisfy the furnace's appetite for charcoal, limestone, and iron ore.

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

Marshall Gold Discovery State Historic Park secures for the people and makes available for their observation, inspiration, and enjoyment, the gold discovery site and its environs as an accurate portrayal of the story that unfolded at the time of the discovery and Gold Rush.

Visitors can see a replica of the original sawmill and over 20 historic buildings including mining, house, school, and store exhibits. Visitors have the opportunity to try panning for gold in the American River and enjoy hikes and picnics under the riparian oak woodlands. Overlooking the river canyon, where the gold discoverer rests today, visitors ca see California's first historic monument, the statue of James Marshall pointing at his gold discovery site .
