The Catoctin Iron Furnace operated from 1776 until 1903, and is located in Cunningham Falls State Park. The furnace site was once a booming industrial complex and community, and utilized the surrounding woodlands for fuel provision. Today, the state park encompasses both the old furnace and the surrounding landscape, and offers visitors an impressive variety of outdoor activities, from hiking to fishing. In addition, visitors can explore much of the Catoctin Furnace historic site.

The site offers visitor information and maps for the state park, along with a fairly detailed history of the furnace.

An engineering marvel originally built in 1884, the Georgetown Loop railroad fulfilled the hopes of Georgetown citizens to become a prosperous settlement connected to Denver and points east. In connecting Silver Plume and Georgetown, towns over 2 miles apart, the tracks scaled an elevation of 640 feet over mountainous terrain, requiring trestles, cuts, fills, loops, and curves totaling 4.5 miles. Today the Loop is once again a popular tourist attraction and an uncommon way to see the Clear Creek Valley. Along the route visitors may stop for guided tours of a historic silver mine. The park is located on 978 acres and includes an 1884 depot, the Morrison Interpretive Center, two 1860s mines, an 1871 mill building, four reconstructed mine buildings, a locomotive maintenance building, the 1874 Pohle House, and a new rolling stock shelter.

In 1854, John Anderson Penn settled in the rugged cedar-covered hills of southwest Dallas County—an area known as the Cedar Mountains. Today, remnants of the original Penn Farm survive intact in the confines of Cedar Hill State Park. Penn Farm Agricultural History Center pays tribute to the disappearing Texas family farm and affords a glimpse into agrarian history as farm machinery took the place of the horse and mule almost a century ago. It includes reconstructed and historic buildings from the mid-1800s through the mid-1900s.

The site offers tours and occasional recreational and educational events.

Old Sacramento State Historic Park is a cluster of noteworthy, early Gold Rush commercial structures. Historic buildings include the 1849 Eagle Theater; the 1853 B. F. Hastings Building, once home to the California Supreme Court; and the 1855 Big Four Building. Old Sacramento's historical significance comes from it being the western terminus of the Pony Express postal system, the first transcontinental railroad, and the transcontinental telegraph. With over 50 historic buildings, Old Sacramento has more buildings of historic value in its 28 acres than any area of similar size in the West.

Fort Richardson was established in November 1867 and was named in honor of General Israel B. Richardson, who died in the Battle of Antietam during the Civil War. The fort was the northernmost of a line of Federal Forts established after the Civil War. The soldiers arrived in Jacksboro in 1866 with orders to establish a fort at Buffalo Springs, 20 miles north of Jacksboro. Due to unhealthy conditions at Buffalo Springs and the constant Indian raids, the fort was abandoned. The soldiers returned to Jacksboro and eventually received orders to establish a fort on the South Bank of Lost Creek. Expeditions sent from Fort Richardson arrested Indians responsible for the Warren Wagon Train Massacre in 1871 and fought Comanches in Palo Duro Canyon. The Fort was abandoned in May 1878.

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

Once the greatest cow trail in the world, the Chisholm Trail served to get Texas cattle north to the Kansas railheads from which they were shipped to the other parts of the country. The main stem of the Chisholm Trail ran along what is now US 81. Cattle were first moved over the trail in 1867. In the ten years from 1867 to 1877, more than three million head of cattle passed through Oklahoma to Kansas. In Kingfisher County all three parts of the trail can be seen. The Chisholm Trail Museum is located directly on this famous trail.

The museum offers exhibits.
