    Overview

    Offered for sale is a 52-acre property in two parcels (18.6 acres and 33.5 acres). The land is positioned for a private estate, with a natural setting that includes a pond and access to significant historical water resources, noted as 1883 water rights for irrigation and stock, supported by an on-site well. Existing improvements and infrastructure include septic, a well, and buried power. The property is also described as having patented mining claims.

    The site borders U.S. Forest Service land, creating direct adjacency to public forest ground for outdoor access, including horseback riding and hiking as described in the remarks. Zoning is listed as BC/R-10, and the overall holding is presented as a legacy-style development canvas.

The combination of established utilities, on-site water rights, and forest adjacency may appeal to owners seeking an equestrian-oriented property or a carefully planned residential development that can be developed from the existing site infrastructure.
