Archaeological Data Recovery for the State Route 77, Five Mile Draw Bridge Project

EcoPlan completed archaeological data recovery at Five Mile Draw Bridge, located on State Route 77 near Snowflake, Arizona. The fieldwork consisted of site mapping, systematic surface collection, shovel testing in areas of high surface-artifact density, excavation within or near mapped surface features, and documentation of a petroglyph panel and a bedrock mortar. The most notable aspect of the Five Mile Draw site is the large petroglyph panel on the site consisting of 30 discrete images, including footprints, connected circles, snakes, birds, and abstract designs, pecked into the side of a massive sandstone boulder. EcoPlan’s interpretation the rock art panel complemented the interpretation of the Five Mile Draw site as a stopping point for multiple cultural groups.



Canoa Ranch Rural Historic District Boundary Modification

In 2015, the Pima County Cultural Resources and Historic Preservation Division tasked EcoPlan with modifying the boundary of the Canoa Ranch Rural Historic District, a large historic property owned by Pima County that was first listed in the National Register of Historic Places (National Register) in 2007. This prompted numerous changes to the many nomination maps, most of which showed either all of the boundary or some portion of it. This was both an editing challenge for the author and a demanding task for EcoPlan’s geographic information systems and graphics specialists, and required revisions to maps, text, graphics, and a table listing contributing and noncontributing buildings and structures. EcoPlan completed the work to modify the boundary and revise the nomination in December 2015, and in February 2016 the Canoa Ranch Rural Historic District was listed once again in the National Register.


US 60: Silver King to Superior

EcoPlan is currently in the midst of this large-scale, multi-phase data recovery project in support of the planned reconstruction of US 60 near Superior for the Arizona Department of Transportation. For this project, EcoPlan was tasked with data recovery at 26 cultural resources (archaeological sites and historic-age structures) that will be subject to effects from construction activities. The Phase I field effort (surface work and testing) began in February 2014 and Phase II (full scale data recovery) began in August 2014. Field efforts at the sites/structures variously included surface collection, detailed mapping, geomorphological assessments, metal detecting, laser scanning, 3-dimensional photogrammetry, extensive backhoe trenching, the excavation of manual, backhoe surface stripping, and manual unit/feature excavation. Investigated feature types include Hohokam pit houses, field houses, thermal and non-thermal pits, agricultural features, and human cremations; Salado single room structures, a roomblock, a large multi-room pueblo, thermal and non-thermal pits, agricultural complexes, inhumations: and historic-era roads, trash dumps and scatters, a blacksmith work area; and utility lines.
