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.

South Pass City has a variety of interesting and educational activities for visitors throughout the summer. When the presence of volunteer staff permits, not only can visitors walk through each of the 17 restored and exhibited original structures, they can enjoy ice-cold sarsaparillas and a game of billiards on a restored 1860s period table, as well as hear the ring of a hammer on steel when the blacksmith shapes hot iron. Each day, one can shop in the historic Smith-Sherlock General Store or pan for gold in the clear waters of Willow Creek. In the Interpretive Center, visitors can also learn about other gold-producing methods that have been used around South Pass City throughout its history.

A second website for the site can be found here.

The site offers exhibits, tours, demonstrations, and occasional educational and recreational events (including living history events).

Bodie State Historic Park is a genuine California gold-mining ghost town. Visitors can walk down the deserted streets of a town that once had a population of 10,000 people. The town was founded by Waterman S. Body (William Bodey), who had discovered small amounts of gold in hills north of Mono Lake. In 1877, the Standard Company struck pay dirt and a gold rush transformed Bodie from a town of 20 people to a boomtown. Only a small part of the town survives, preserved in a state of "arrested decay." Interiors remain as they were left and stocked with goods.

The park offers exhibits and tours.

The Center prepares visitors for an adventure along the western historic trails. Here, they can receive an orientation for trips north following the Lewis and Clark Trail or for trips west following the routes of early travelers on the Oregon, Mormon, and California Trails. They can enter the Lied Historical Building on the Path of Names to enjoy educational exhibits, maps, films, and sculpture.

The site offers short films, exhibits, and occasional recreational and educational events (including living history events).

This Powder River was the vein of life during the boom days of the gold rush. The landscape still bears the scars. Miles of tailings line the banks of the river, a remembrance from the prosperous days of mining. The Sumpter Valley Dredge left much of the rocky footprint that visitors can see on their trek along Highway 7. The dredge is an important link to Oregon's pioneering past and development. It is one of the largest and most accessible gold dredges in the U.S., and the last of three built on the Powder River. Built in 1935, it ran until 1954. It dug up more than four million dollars worth by a simple, but dramatic method.

The site offers interpretive services, according to the website; however, the services are not described.
