Keystone Hotel
Douglas County
The 1901 two-story commercial building, along with its 1910 addition served as a social hub of the community.
For many years it was the only hotel in town, and a saloon or restaurant continuously occupied the corner location from 1901 until the 1960s. The building is a good example of the use of locally quarried rhyolite.
