Rimrock School is located in a still rural setting south of US Hwy. 50, near the Curecanti National Recreation Area and the Black Canyon of the Gunnison National Park. 

Built in 1900, the Pitkin Town Hall is significant for its role in the history of Pitkin and for its architectural features.  The building was designed/built by F.G. Zugelder, a prominent stonemason, and William Ender.  In 1908, the town hall was enlarged. 

From 1924 until 1962, the wood frame building was the only school serving Pitkin and the surrounding area. 

The hotel is a strong example of the commercial buildings constructed in small mining towns at the turn of the century. 

The Alpine Tunnel Historic District includes approximately 13 miles of the former Denver, South Park and Pacific Railroad railbed across the Continental Divide from Hancock to Quartz, as well as the Alpine Tunnel itself.

Originally known as St. John’s Episcopal Chapel, the church was built in Aspen in 1886 by the Episcopal Missions of Western Colorado.  In 1908, it was relocated to Marble and was renamed St. Paul’s Church.  Two rooms were added to the rear of the building, and a belfry was added in 1911.  The church is Marble’s only example of Gothic architecture and is an example of early religious structures of late 19th century mining communities in Colorado. 

Constructed in 1891, this house was built by William D. Parry, who along with William Wood, was responsible for founding the town of Marble.

Built circa 1908, the Marble Town Hall is significant for its Dutch Colonial Revival architectural features, and for its role in the development of the town of Marble.  As many as ninety-one cottages were built in Marble in response to the housing shortage created by the establishment of the Colorado-Yule Marble Company in 1905. 

Constructed sometime between 1896 and 1905, the mill produced marble that was used in the construction of the Lincoln Memorial and in the Tomb of the Unknown Soldier as well as a host of significant buildings in Oregon, California, and Colorado. 

The Marble Jailhouse was built in 1901 to accommodate a rapidly growing population drawn to the area by the economic activity of the Marble quarry.
