The Redstone Historic District is located in and near the unincorporated community of that name in western Pitkin County, Colorado, United States. It includes the original community of Redstone as built by Colorado Fuel and Iron (CFI) for the coal miners it employed. In 1989 it was recognized as a historic district and listed on the National Register of Historic Places. Redstone was originally a company town. John Cleveland Osgood, CFI's president at the time, spent lavishly to create quality housing for miners and their families, as well as various other public buildings, in an effort to forestall unionization. Architect Theodore Boal designed simple yet attractive structures by adapting various Victorian architectural styles. The district includes as contributing properties Osgood's estate, Cleveholm, and the Redstone Inn. At first very populous and successful due to the high production capacity of the nearby coke ovens, Redstone was almost abandoned within a decade when it became too costly to transport coke from the remote community to CFI's new steel mill. A handful of residents remained, keeping Redstone from becoming another one of Colorado's many ghost towns. Some of its original buildings were demolished over the years. Eventually the town rebounded slightly and today is home to a small arts community; many of the remaining buildings have been restored. It is one of the few intact company towns remaining in the state.

The Redstone Inn is located on Redstone Boulevard in Redstone, Colorado, United States. It is a structure in the Tudor Revival architectural styles built at the beginning of the 20th century. In 1980 it was listed on the National Register of Historic Places. It is also a contributing property to the Redstone Historic District listed on the register nine years later. When it was built, it served as a dormitory for unmarried male workers, primarily miners, at the Colorado Fuel & Iron (CF&I) company's coal mines and coking ovens nearby. It was part of the company town, with modest cottages for the miners and their families as well as a school, recreation center, firehouse and other public buildings, that CF&I president John Cleveland Osgood, had spent lavishly to create along with his nearby estate. The mines were closed in 1908, and the village nearly abandoned, the dormitory among them. Most of its original buildings were demolished or moved, but the dormitory survived, and was restored and converted to its current use in mid-century.

The Redstone Coke Oven Historic District is located at the intersection of State Highway 133 and Chair Mountain Stables Road outside Redstone, Colorado, United States. It consists of the remaining coke ovens built at the end of the 19th century by the Colorado Fuel and Iron Company. In 1990, it was recognized as a historic district and listed on the National Register of Historic Places. Two hundred were built, because the coal in the surrounding mountains was ideal for refining into coke. At their peak, they were producing almost 6 million tons a year. The development was the beginning of the modern settlement of Redstone. There are very few coke ovens of their type remaining in the West; the ovens are themselves the only remnant of the sizable coking operation in the area, the largest at the time in Colorado. Within ten years of their construction the ovens fell into disuse when the mines closed. Their support steel was removed during the scrap metal drives of World War II, and later they were used as living space by hippies who moved into Redstone. The possibility that some might be demolished to build a gas station eventually led Pitkin County to acquire the land in the mid-2000s, and since then some have been restored.

Redstone Castle, also known as Cleveholm or Osgood Castle, is a mansion south of Redstone, Colorado, United States. It is a large timber frame structure built in the early 20th century as the home of John C. Osgood, founder of the Colorado Fuel and Iron Company, in a simplified version of the Stick style. In 1971 it was added to the National Register of Historic Places, the first property in Pitkin County to be listed. It was later additionally listed as a contributing property to the Redstone Historic District. The castle was at the south end of the planned company town of Redstone, meant by Osgood to be an improvement over the usual housing and conditions in Western mining towns of the late 19th century. Just across the Crystal River were the coke ovens that processed coal mined higher up in the mountains and loaded onto a rail line. Miners and cokers in the town lived in cottages with electricity and running water, considered luxury items at the time. At his mansion, Osgood, at the time one of the country's richest men, entertained guests like Theodore Roosevelt, John D. Rockefeller and King Leopold of Belgium, who joined him on hunts. The lush interior features European antique furniture and work by Gustav Stickley and Louis Comfort Tiffany. Its design was supposedly based on the ancestral home of Osgood's wife Alma.Redstone's prosperity ended within a decade, after Osgood lost control of the company, and he spent less time there. He returned to the property in the late 1920s to die. His wife tried to convert the house into a resort, but the Great Depression made that economically unviable; however, later owners were able to run it as a hotel into the 1990s. A recent owner who tried to refurbish was indicted in a financial fraud scheme, and the Internal Revenue Service sold it to compensate victims in its first-ever online auction of seized real property. It was sold again in 2016, and after a renovation, owners Steve and April Carver opened a ten-room boutique hotel in the castle in November 2018. It is also open for daily public tours. The 2006 film The Prestige used the castle as a location.

The Osgood Gamekeeper's Lodge is located along State Highway 133 near Redstone, Colorado, United States. It is a timber frame structure built at the beginning of the 20th century. In 1989 it was listed on the National Register of Historic Places. Architect Theodore Boal designed the house in the Swiss chalet style, one of many in Redstone at that time. He had been commissioned by John C. Osgood, then owner of the Colorado Fuel and Iron (CFI) company, who designed the small community as a company town for the coal miners and other workers CFI employed in the area. Osgood's estate included two large private game preserves for himself and his guests, who included Theodore Roosevelt, John D. Rockefeller and King Leopold II. Less than a decade after it was built, Redstone was almost completely abandoned. Many of its original houses and cottages were torn down or moved in later decades, even as Redstone itself revived slightly as an arts colony. The gamekeeper's cottage is one of the few outside the village that remain relatively unaltered. It continues to be used as a private residence.

Spring Gulch is a cross-country ski area located on Thompson Creek Road in northwestern Pitkin County, Colorado, six miles west of Carbondale, Colorado, USA. The ski area shares its name with a historical 19th and early 20th century coal mining townsite, Spring Gulch, which is in the vicinity mostly to the south of the ski area proper. The area is run by the non-profit Mount Sopris Nordic Council for the benefit of community members and visitors. Use of the area is free of cost and limited to cross-country skiing activities. The terrain consists primarily of rolling trails among gambel oak and aspen trees. Views of the nearby Mount Sopris and Elk Mountains are visible from some of the higher trails. The area was formed in cooperation with the local North Thompson Cattlemen's Association, which owns the land and uses it for summer grazing, during which time it is closed to all recreational use. Notable annual events include the Ski for Sisu fundraiser, the Alpine Bank Classic high school Junior Olympic qualifiers, and the Colorado Rocky Mountain School Rat Race. Spring Gulch is the primary training ground for the Nordic team at CRMS.
