The project will document new archeological sites and visit all previously recorded sites (n = 44) within the units and re-record and/or update data to meet current standards. These assessments are needed to meet Section 110 cultural resource identification, assessment, and evaluation, and Section 106 compliance for the identification of historic properties prior to undertakings, as required in the National Historic Preservation Act of 1966, as amended. This effort assists the park in long-term planning for management of the backcountry especially along the heavily used corridor trails where mitigation of resource damage is most immediate. Data from this project will support GRCA effort to rewrite its Backcountry Management Plan beginning in 2010. Keywords: Archeology, Trail, Condition Assessment, Planning, Compliance 2
