About this file
This document is a Cultural Resource Desktop Review prepared by Kleinfelder for NEO Connect and the Southwest Colorado Council of Governments, focusing on the Cortez to Towaoc Fiber Line Project in Montezuma County, Colorado. The report provides a comprehensive desktop analysis of cultural resources within a 0.25-mile buffer of the proposed fiber line project area, identifying 46 previously documented cultural resource sites and 26 previously conducted cultural resource studies. The review highlights the project area's high sensitivity for cultural resources, noting the proximity to prehistoric and historic-era sites, nearby freshwater sources, Holocene-age alluvial soils, and the landscape's shallow slope.
The desktop review emphasizes the need for an intensive pedestrian inventory to fully identify potential cultural resources within the project area. Several notable sites were identified, including prehistoric archaeological sites with features like rubble mounds, kivas, and roomblocks, and historic sites such as highway segments, culverts, and farm properties. The project area is located partially within or adjacent to the Ute Mountain Ute Reservation, with a rich historical context dating back to the Ute tribe's traditional territories. The report recommends further archaeological investigation to ensure proper cultural resource management during the fiber line project's implementation, given the area's significant archaeological potential.

1 INTRODUCTION
NEO Fiber, Inc., doing business as NEO Connect, was hired by the Southwest Colorado Council of Governments (SWCCOG), in collaboration with the Ute Mountain Ute Tribe to complete an environmental review and biological survey for the proposed Cortez to Towaoc Fiber Line Project
(Project) located in Montezuma County, Colorado. At the request of NEO Connect, Kleinfelder, Inc. (Kleinfelder) completed a desktop cultural resources review for this route. This report has been prepared to summarize the previously recorded archaeological and historic resources in the
Project Area that may require design and permitting consideration during planning and construction of the Project.
Soils within the Project area predominately consist of Mikim (s1418) deposits with Witt-Sharps-
Cahona (S1426) and Panitchen-Lillings (s1419) deposits located within the northernmost extent of the Project area (SoilWeb 2021). Surface soils within the southern portion of the Project area predominately consist of Mikin loam with 3 to 6 percent slopes with Ramper loam, 0 to 3 percent slopes and Ustic Torriorthents-Gullied land complex, 1 to 60 percent slopes, along waterways.
Surface soils within the central and northern portions of the Project area are more diverse and include: Barx-Gapmesa complex, 2 to 6 percent slopes; Fluvents-Fluvaquents complex, 0 to 3 percent slopes; Mikket clay loam, 0 to 3 percent slopes; Mikettt clay loam, saline-sodic, 0 to 3 percent slopes; Mikim loam, 3 to 6 percent slopes; Mikim clay loam, 1 to 3 percent slopes; Mikim clay loam, sodic, 0 to 3 percent slopes; Rizno-Gapmesa complex, 3 to 9 percent slopes; Romberg-
Crosscan complex, 6 to 25 percent slopes, very stony; Sideshow silty clay loam, 6 to 12 percent slopes; Ustic Torriorthents-Gullied land complex, 1 to 60 percent slopes; and Wauqyuie very stony loam, 6 to 25 percent slopes, very stony (SoilWeb 2021). The predominate surface soil types are
Mikim soils, alluvium derived from sandstone and shale that generally form in alluvial fans, are generally well drained, and are not naturally prime farmland (SoilWeb 2021). Vegetation associated with the soil type most often include alkali sacaton (Sporobolus airoides) and galleta
(Pleuraphis jamesii) as well as western wheatgrass and various sagebrushes and saltbushes
(SoilWeb 2021).
HISTORIC CONTEXT
The Project area is located within the territory of the Ute Tribe. The Ute would settle in seasonal camps with winter encampments often settling near rivers with intertribal mobility provided via
20220811.001A/DEN21R128000 Page 2 of 11 June 2021
KLEINFELDER 707 17th Street, Suite 3000, Denver, CO 80202 p | 303.237.6601 intertribal marriages and conflicts. At the time of European contact, it is estimated that the Ute tribe had a population of 7,500 (Bakken and Kindell 2006). The Project area is situated partially within or directly north of the Ute Mountain Indian Reservation which encompasses 553,008 acres in Colorado and New Mexico. The land belongs to the Ute Tribe (Bureau of Indian Affairs 2021).
The Ute Mountain Ute Tribe are comprised of the Weeminuche band of the Ute Nation of Indians, with the two other bands of the Ute Nation of Indians (the Mouache and the Capote) forming the
Southern Ute Tribe. The Ute tribe is distinguished from neighboring tribes by their use of the Ute language, which is Shoshonean. The Tribe currently has a population of over 2,000 members.
The traditional territory of the Weeminuche band includes the western flank of the Rocky
Mountains in the current states of Utah, Colorado, Arizona, and New Mexico, bounded by the
Continental Divide to the east and the Abajo Mountains in Utah to the west (Ute Mountain Ute
Tribe 2021).
By 1882, the Project area was depicted as an undeveloped area, with the closest settlement depicted on maps being the city of Dolores, approximately 11 miles northeast of the Project area
(Cram 1882). By 1891, the Southern Ute Indian Reservation (later designated as the Ute
Mountain Indian Reservation within the vicinity of the Project area) had been established and the city of Cortez was depicted, but the Project area otherwise remained relatively undeveloped
(Appleton 1891). By 1959, the Project area was essentially fully developed in its modern configuration with Highway 666 (later named Highway 160) built along its modern alignment and irrigation ditches built crossing the Montezuma Valley (USGS 1958). Several residences and agricultural buildings are located along the Project corridor in addition to sideroads and irrigation ditches (Google Earth Pro 2021).

2 PREVIOUSLY IDENTIFIED RESOURCES
Kleinfelder requested a file search of a 0.25-mile buffer around the Project area through the
Colorado Office of Archaeology and Historical Preservation (OAHP) and the results were received on June 21, 2021 (File Search No. 23789). The results identified 46 previously documented cultural resource sites and 26 previously conducted cultural resource studies within the records search area. The results are presented in Tables 1 and 2 below and are depicted on Attachment

Many of the studies listed above in Table 1 overlap the Project area, as many were centered along the Highway 160 corridor (see Attachment A: Figure 3). Of note, MT.CH.R27 essentially extends along the entirety of the Project area, with the exception of the segment of the Project area located along Road G. MT.CH.R27 consists of an intensive 114.57-acre inventory conducted in 2014 by Greg Wolff at the Colorado Department of Transportation (CDOT) of Highway 160 between Towaoc and Cortez.
Likewise, several recorded sites (5MT.22131 and 5MT.22131.2) encompass the majority of the
Project area (Attachment A: Figure 4). These sites both consist of segments of Highway 160 and should not be impacted by Project implementation. Previously recorded site 5MT.4342 (Ute
Mountain Ute Mancos Canyon Archaeological District/Ute Mountain Tribal Park) is located either within or directly adjacent to the southern end of the Project area and overlaps a segment of the

It is unclear from the records if any contributing elements of the district are located directly within the Project area. Additionally, recorded sites 5MT.13716 (a historic culvert), 5MT.21904 (a historic box culvert), 5MT.22133 (the historic Schwindt Farm), 5MT.22134 (the historic Baacke Property), 5MT.22135 (historic Wood’s
Food Store and Gas Station), and 5MT.22795 (the historic Hoppenhafer Ranch/Centennial Farm) are located either within or directly adjacent to the Project area, along either side of Highway 160.
None of these historic-era resources should be impacted by Project implementation. The remaining resources are located between Highway 160 and the extent of the 0.25-mile records search buffer (see Attachment A: Figure 4).

3 SUMMARY
Based on the results of the desktop review and the OAHP file search, the Project area appears to be highly sensitive for cultural resources. The close proximity of both prehistoric and historic-era sites, the relative proximity of freshwater sources, the Holocene-age alluvial soils underlying most of the Project area, and the shallow slope of the landscape within the Project area all indicate an increased potential for cultural resources. It is important to note that there may be yet unidentified cultural resources within the Project area. Only an intensive pedestrian inventory of the entire Project area would result in the identification of any and all sites within the Project area.
