Phase I reconnaissance survey was conducted on S.P. 2610-10 from the intersection with Highway 55 in Barrett, Minnesota, south along TH 59 to the Grant County Iine. The survey consisted of three parts. A geomorphic survey was conducted to determine the subsurface stratigraphy, particularly potential for paleosoils, along the corridor. An archeological survey tested for the presence of archeological sites, using both pedestrian walk-over and shovel tests. A standing structure review was conducted of all structures with 100 feet of the highway. The object we was to assess the potential for and presence of historical properties that might receive impacts from the undertaking.
Pre-contact cultural materials were recovered 15 locations. Of these, 12 sites appear to be limited lithic scatters or isolated find spots; these sites are considered not eligible for the National Register. The other 3 sites yielded more materials and could potentially be more than limited lithic scatters. Coring date at each site provided information on subsurface stratigraphy and potential for subsurface integrity. Sites evaluated immediately south of the project uniformly had nearly all cultural materials confined to the upper dark horizon (whether plow zone or A horizon).
Site 21GR27 may have some original A horizon remaining below the plow zone. If impacts cannot be avoided, a limited evaluation is recommended. Site 21 GR31 appears to have good potential for intact subsurface deposits in die grassy area, although the plowed field appears to be disturbed. If impacts cannot be avoided, an evaluation is recommended. Site 21GR34 does not appear to have any A horizon materials below the plow zone. It is considered not eligible for the National Register.
It is recommended that management considerations need to be made for sites 21GR27 and 21GR31. Avoidance of the site areas is recommended; alternatively, evaluation could be conducted to determine eligibility for the National Register.
