The arrastra is an important example of nineteenth- and twentieth-century milling technology. This specimen is unusual because it used a wooden wheel as the pivot mechanism; only two of this type are owned by the National Park Service. It is considered regionally significant because it is the only wagon wheel arrastra yet found possessing integrity of location and construction.
