The Lost Canyon settlement may establish the extreme northern extension of Mesa Verde related habitation communities.

Consisting of one architectural unit that dates between AD 750 and 850 and six architectural units that were generally occupied between AD 1000 and 1150, the site has the potential to yield important information regarding village organization during the Pueblo I and II periods.

Constructed in 1889, the property is associated with the early settlement of Mancos and was the residence of George Bauer, a pioneer merchant and banker, who occupied the house until his death in 1905.  He was also a stone mason and assisted in the construction.  In 1881, Bauer established the first store in Mancos. 

The 1905 building is the only remaining evidence of the town’s successfully orchestrated effort to defy the Rio Grande Southern Railroad by constructing substantial commercial buildings southeast of the railroad’s siding.  This effort established the commercial core of the town closer to the river and set the pattern of development for Mancos as it is known today.

Constructed in 1893, with a 1902 addition, this is the oldest building in Dolores.  The 2½-story building, which took its name from the railroad line, was the first hotel in town. 

The 1917 house is a good local expression of the Craftsman style.  Despite the enclosure of the porch, the home possesses distinctive characteristics of the style as seen in the full-width front porch with its short, square columns resting on larger piers, the triangular knee braces along the sloping edges of the roof, and the roof’s overhanging open eaves with exposed rafters. 

This residential cluster of eleven unit pueblos with a focus of occupation between AD 1075 and 1150 has potential to yield important information about community formation and population dynamics in the central Mesa Verde region.  As the site is larger than a household but smaller than a community, it holds an important place in the evolution of prehistoric Puebloan society.

The school is associated with the educational, recreational, and social activities of the Lebanon community.  It is an interesting example of the Classical Revival style in a rural schoolhouse.

This gasoline-powered narrow gauge railroad car, constructed in 1933, provided the Rio Grande Southern Railroad with a cost saving alternative to the more expensive steam locomotive passenger trains and allowed the company to continue operating in the San Juans until 1952.  A gasoline engine is under the hood of a 1928 Pierce-Arrow touring car.

Noted in the journals of Father Silvestre Escalante during a 1776 expedition, this is the first recorded archaeological site in what is now the state of Colorado.
