    ABSTRACT

    ERO Resources Corporation (ERO) performed an additional Class III intensive

    cultural resource inventory for the Energy Fuels Resources (EFR) Pion Ridge Mill

    Project. The area of potential effect (APE) consists of one contiguous

    The parcel is located in Paradox Valley,

    The inventory resulted in documentation of four new archaeological sites and two

    isolated finds. Most sites are open lithic scatters. Two sites include a historic component

    one consists of a historic can scatter and the other is the remains of a homestead. All

    but one site are recommended not eligible for listing on the National Register of Historic

    Places (NRHP) due to their limited research potential beyond current documentation. A

    portion of site 5MN9206 is recommended eligible for the NRHP based on the potential

    for a buried thermal feature. Isolated finds, by definition, are not eligible for inclusion in

    the NRHP.

    A determination of no historic properties affected, pursuant to 36 CFR 800.5 of the

    National Historic Preservation Act (NHPA), is recommended for the project area,

    contingent upon concurrence by the Colorado State Historic Preservation Office (SHPO).

    All four sites will be avoided by further ground disturbance, where feasible, regardless ofeligibility.

    JULY 2009

    IntroductionERO Resources Corporation (ERO) performed a Class III intensive cultural resource

    inventory for the Energy Fuels Resources Corporation (EFR) Pion Ridge Mill Project

    (Pion Ridge project). The area of potential effect (APE) consists of one contiguous

    The parcel is located in Paradox Valley,

    The original scope of the Pion Ridge project included an 880-acre property proposed

    for a uranium processing mill. In 2007, that 880-acre portion of the project was

    inventoried by ERO (Whitfield et al. 2007). Mitigation work at two prehistoric

    archaeological sites within the original project area is detailed under Sheptow and

    Larmore (2009). A more detailed description of the original project and the results of the

    original inventory can be found in the 2007 cultural resource inventory report (Whitfield

    et al. 2007). The current inventory report pertains to an additional where EFR

    intends to install ground water wells and construct access roads as part of the Pion

    Ridge project. The additional are located on private property adjacent and

    west of the original 880-acre project area. Regulatory review is being provided by the

    Colorado Department of Public Health and Environment (CDPHE).

    The project is located in the N of the SE of Section 7, Township 46 North, Range

    17 West, New Mexico Principal Meridian (PM). The parcel is located on the Davis Mesa

    USGS 7.5 topographic quadrangle (Figure 1).

    Site Evaluation CriteriaSites investigated during this inventory were evaluated for eligibility to the National

    Register of Historic Places (NRHP). NRHP significance criteria are codified under 36

    CFR 60.4 and are specified below.

    The quality of significance in American history, architecture, archaeology, and

    culture is present in districts, sites, buildings, structures, and objects that possess integrity

    of location, design, setting, materials, workmanship, feeling, and association, and:

    a) that are associated with events that have made a significant contribution to thebroad patterns of our history; or

    b) that are associated with the lives of persons significant in the past; or

    c) that embody the distinctive characteristics of a type, period, or method ofconstruction, or that represents the work of a master, or that possess high artistic value, orthat represent a significant or distinguishable entity whose components may lackindividual distinction; or

    d) that have yielded, or are likely to yield, information important in prehistory orhistory.

    Ordinarily, cemeteries, birthplaces, or graves of historical figures; property owned by

    religious institutions or used for religious purposes; structures that have been removed

    from their original location; reconstructed historic buildings; properties that are primarily

    commemorative in nature; and properties that have achieved significance within the last

    50 years shall not be considered eligible for the National Register. However, such

    properties will qualify if they are integral parts of districts that do meet the criteria, or if

    they fall within the following categories:

    a) a religious property deriving primary significance from architectural or artisticdistinction or historical importance; or

    b) a building or structure removed from its original location but which is significantprimarily for its architecture, or which is the surviving structure most importantlyassociated with a historic person or event; or

    c) a birthplace or grave of an historical figure of outstanding importance if there isno other appropriate site or building directly associated with his or her productive life; or

    A pedestrian survey was conducted by walking transects spaced 15 to 20 meters

    apart. Once artifacts were located, the survey was halted and systematic inspection of the

    area was conducted by pinflagging all observed artifacts and features. Artifact

    concentrations were identified at the discretion of the crew chief based on artifact

    distribution. Two site overviews and all features and diagnostic artifacts were digitally

    photographed. A site datum, diagnostic artifacts, and site and artifact boundaries were

    documented using a submeter Trimble GeoXT Explorer Global Positioning System

    (GPS) unit. No permanent datum was established.

    A cultural resource is defined as the locus of previous human activity at which the

    preponderance of evidence suggests one-time diagnostically interpretable use, repeateduse over time, or multiple classes of activities. Professional judgment is used to

    distinguish between purposeful activity and isolated occurrences of artifacts that are often

    attributable to background noise. Isolated thermal features, rock art panels, and

    isolated human burials are considered archaeological sites. Surface lithic scatters that

    occur in a condensed area and comprise a single raw material may be attributable to a

    single reduction episode that is not considered representative of purposeful activity or

    patterned behavior sufficient to be documented as a site. However, due to the paucity of

    documented sites in Paradox Valley, these types of activity loci were documented as

    archaeological sites. Project localities with surface lithic raw material may produce a

    preponderance of such occurrences; however, this is not the case in Paradox Valley

    where the surface is blanketed with eolian deposits. There is no precise threshold of

    lithic flakes required to advance an isolated occurrence of lithic reduction to that of an

    archaeological site, but a standard of 10 to 15 pieces of debitage is often used as an

    arbitrary threshold. An evaluation of raw material, flake density, and spatial distribution

    is required to make an informed decision of isolated reduction episodes. Lithic scatters

    with multiple raw materials and artifact classes are generally considered archaeological

    sites. The presence of ground stone or features in association with flaked lithic material

    qualifies as a camp location. A ceramic scatter representative of a single vessel is also

    considered an isolated find.

    Historic sites are evaluated using the same criteria outlined above. Isolated historic

    artifacts are generally recorded as isolates unless associated with purposeful activity such

    as habitation, ranching or agricultural, or mining complexes. Historic dumps are

    evaluated on a case-by-case basis. A single artifact class such as sanitary cans is

    recorded as an isolated occurrence; conversely, dumps that exhibit many artifact classes

    and date prior to the 20th century are documented as archaeological sites. Linear features

    such as water conveyance systems, transmission lines, and roads are documented as sites.

    An isolated fence line is generally not recorded as a site unless it demarcates a boundary

    significant to area history. An isolated mine adit with no associated artifacts or features

    is also recorded as an isolate.Prehistoric artifact descriptions use the following terminology in this report: Ground

    stone descriptions follow Adams (2002); biface stages are defined according to

    width/thickness ratios (Callahan 1979) and are illustrated and discussed in Andrefsky

    (1998); flake terminology follows the triple cortex typology of primary, secondary, and

    tertiary (Andrefsky 1998), which correspond to the amount of cortex present on the flake.

    A primary flakes exterior surface is covered in cortex over 50% of its surface; secondary

    flakes have less than 50% cortex; and tertiary flakes exhibit no cortex. Although the

    flaws in this method of flake typology are inherent (Andrefsky 1998), it does characterize

    a sites surface flake assemblage in an efficient manner while providing useful data.

    Projectile point analysis follows procedures adopted by Larmore (2002), which relies

    on metric attributes of the haft and morphological attributes that emphasize existing

    condition and cross-section; typological assessment is dependent upon project location,

    but general typologies consulted include: Buckles (1986), Frison (1991), Holmer (1978,

    1986), Irwin-Williams (1973), Pitblado (1999), and Thomas (1981). Most typologies in

    the region borrow heavily from these sources. Grey literature sources are consulted when

    significant previous investigations have occurred in the area. Six hafted bifaces were

    collected during the course of the inventory and will be returned to EFR following

    analysis.

    Site Descriptions

    Site Number: 5MN9206

    Site Type: Open Lithic Scatter

    Site Description: The site is located

    . Scattered pinyon-juniper is the dominant vegetation with typical Upper

    Sonoran understory. The elevation is 5,475 feet (1,669 meters) above sea level (asl).

    Material culture includes flaked lithic debitage derived primarily from locally

    available Dakota quartzite and silicified sediment with some chert from an unknownsource. Flakes are diffusely scattered over a large area and concentrated in two general

    areas. Burnt fragmented bone occurs as Field Specimen (FS) 2 in an area of small

    tertiary retouched flakes. Two artifact concentrations were identified as AC 1 and AC 2.

    AC 1 contains 20 to 30 flakes primarily of orthoquartzite, and AC 2 consists of about 30

    flakes and burnt bone fragments that probably represent an activity area. The site

    represents a short-term occupation with primary activities including stone tool

    manufacture and retooling. One diagnostic Duncan (McKean Complex) projectile point

    (FS 1) was located indicating a Middle Archaic occupation (3000 to 1000 B.C.) at the site

    (Larmore 2002).

    Management Recommendation: Avoid and protect. This site is recommended

    eligible for the NRHP. Although previous geomorphological studies (summarized in

    Whitfield et al. 2007) have demonstrated that sites on this landform are entirely surficial

    or near surface manifestations, the presence of fragmented burnt bone suggests the

    potential for a buried thermal feature and activity detritus. As such, AC 2 is consideredthe contributing portion of the site and the area peripheral to this concentration is

    recommended as noncontributing to the sites overall NRHP eligibility.

    Site Number: 5MN9207

    Site Type: Open Lithic Scatter

    Site Description: The site is located

    . Artifacts are located

    Dominant vegetation includes

    pinyon-juniper with rabbitbrush, snakeweed, and bunch grasses. The elevation is 5,518

    feet (1,682 meters) asl.

    The site appears to be a limited activity area for lithic reduction, stone tool

    manufacture, and general retooling. Tools include discarded biface fragments (Stages 3-

    5) all of different raw material (FS 1-FS 4), a hammerstone (FS 5), a mano (FS 6), and an

    exhausted core (FS 7). One possible Late Paleoindian biface midsection (FS 8) was also

    identified; flaking is random but well executed, the cross section is bi-convex/diamond-

    shaped, and the raw material is a high quality dendritic chalcedony. The debitage is light

    overall and limited to less than 20 flakes of primarily Dakota orthoquartzite. The high

    tool to flake ratio, coupled with FS 8, suggests the potential for a Late Paleoindian period

    occupation.

    Management Recommendation: No further work. ERO recommends the site not

    eligible for the NRHP. Given the site location in an area of colluvial sediments and near

    surface fan deposits, there is little potential for significant buried cultural deposits.

    Current documentation has exhausted the research potential of the site.

    Site Number: 5MN9208

    Site Type: Open Lithic Scatter/Historic Can Scatter

    Site Description: The site is located

    . Artifacts are located

    Dominant vegetation includes

    pinyon-juniper with rabbitbrush, snakeweed, and bunch grasses. The elevation is 5,531feet (1,686 meters) asl. The ridge slopes 5 to 7 degrees to the northeast.

    The site appears to be a limited activity area for lithic reduction, stone tool

    manufacture, and retooling. Tools include three biface fragments of Dakota

    orthoquartzite (FS 4, FS 7, and FS 8); an expedient projectile point/hafted knife

    manufactured from a retouched flake (FS 1); two cores (FS 2 and FS 6); a sandstone one-

    handed mano (FS 3); a petrified wood retouched flake (FS 5); and a serrated projectile

    point tip (FS 9). The debitage is light overall and limited to less than 20 flakes of Dakota

    quartzite, quartzite, variegated chert, and chalcedony. A stacked rock wall of unshaped

    sandstone (F 5) is located along the western edge of the drainage downslope of the main

    artifact concentration and appears to have been a hunting blind, and is L-shaped and

    measures about 2 meters long. No diagnostic artifacts were present to provide temporal or

    cultural-historical interpretation.

    The historic component is limited to a scatter of about 25 hole-in-cap and sanitary

    cans near the southern or upslope portion of the site and is probably related to the

    homestead documented as 5MN9209. General Land Office (GLO) records indicate the

    north half of the southeast quarter of Section 7 was purchased on July 16, 1913 by James

    M. Belisle. It remains unknown whether this person was responsible for the historic

    cultural manifestations, but they may be associated.

    Management Recommendation: No further work. ERO recommends the site not

    surface bedrock, there is little potential for significant buried cultural deposits. Current

    documentation has exhausted the research potential of the site.

    Site Number: 5MN9209

    Site Type: Open Lithic Scatter/Historic Homestead

    Site Description: The prehistoric component of the site consists of cultural material

    scattered over a large area

    Artifacts occur primarily

    Vegetation in thearea is pinyon-juniper with typical Upper Sonoran understory. The elevation is 5,498

    feet (1,676 m) asl.

    Flaked lithic debitage is dominated by secondary flakes of Dakota orthoquartzite

    locally available in the area. Raw material also includes presumably local variegated

    chert and silicified sediment derived from the Morrison, Dakota, and Burro Canyon

    formations that outcrop in the general area. Tools include two retouched flakes (FS 1 and

    FS 20); seven manos (FS 2-6, 16, and 17); six metates or metate fragments (FS 7, 8, 10,

    11, 18, and 19); a retouched flake/knife (FS 9); a Gatecliff Contracting Stem (Thomas

    1981) projectile point (FS 12); a translucent chert Rosegate (Holmer 1986) projectile

    point (FS 13); a Stage 3-4 biface fragment (FS 14); and a Dakota orthoquartzite

    nondiagnostic biface haft (FS 15). Five of the manos (FS 2-6) comprise a cache (F 4) and

    one of the metates was incorporated into the wall of a historic feature (F 3).

    The Gatecliff Contracting Stem point and Rosegate projectile point indicate

    occupation during the Middle to Late Archaic and early Formative periods, respectively.

    The site represents short-term occupation primarily for lithic reduction and stone tool

    manufacture and vegetal resource (pinyon nut?) processing. Each interfluvial ridge

    probably represents an activity loci or discrete occupation. It is problematic to define

    concentrations due to significant colluvial slopewash, artifact redeposition, and the low

    intensity distribution of artifacts.

    The historic component of the site consists of two structures located on an interfluvial

    ridge of a larger alluvial fan; a third feature is located on the toe slope of the valley floor.

    Feature 1 (F 1) is a 10 x 5 foot dugout cellar excavated into the east side of the

    interfluvial ridge. F 1 was constructed of axe-cut juniper posts, much of which is still

    intact except for the material that once covered the roof. F 2 is a 20 x 30 foot milled

    lumber habitation structure that has largely been salvaged of material. Lumber detritus

    has been mounded in the middle of the feature with smaller debris cached as a packrat

    midden. The outline and distribution of lumber provides a fairly distinct structural shape.

    The pad for the structure was excavated out of the slope in the southwest and southern

    edge, and mounded and leveled near the northeast corner for the platform. The refusedump is located east of F 1 and FS 2, and consists of a medium density of solder dot cans

    (EST 556); aqua, purple, clear, and pane glass; and porcelain fragments. Feature 3 (~8

    foot x 13 foot) appears to be an extramural structure located east of the main historic site

    area. Feature 3 is U-shaped, opens to the west, and consists of a single course of

    unshaped local sandstone rock. No artifacts were located in association. General Land

    Office (GLO) records indicate the portion of Section 7 in which the homestead is located

    was purchased on July 16, 1913 by James M. Belisle. It remains unknown whether this

    person was responsible for the historic cultural manifestations. The artifact assemblage,

    in conjunction with the GLO records, indicates occupation of the site during the late 19th

    to early 20th centuries.

    The overall quantity and density of cultural materials indicates relatively short-term

    occupation by a small family. The artifact type indicates that females and small children

    were not primary constituents of the site. The site has limited archaeological potential;

    no privy was located and the habitation structure has no cellar. The landform

    (interfluvial fan deposits) is not conducive for buried deposits.Management Recommendation: No further work. ERO recommends the site not

    eligible for the NRHP. Subsurface testing at adjacent sites along the same landform

    indicates that buried cultural deposits are unlikely. No prehistoric features were located

    Isolated Finds

    Two isolated finds (IF) were recorded during the inventory. Isolated find 5MN9210

    consists of 14 primary and secondary flakes of Dakota orthoquartzite that collectively

    represent one reduction event; flakes have been redistributed downslope due to colluvial

    slope wash. Isolated find 5MN9211 is an isolated hunting blind located on the west sideof an entrenched ephemeral drainage. Flood events have pushed large boulders to the

    edges of the drainage. A small (~1 meter diameter) circular hunting blind was

    constructed by removing boulders from the interior. No artifacts were found in

    association.

    Summary and Management RecommendationsThe additional cultural resource inventory related to EFRs Pion Ridge project

    resulted in the documentation of four new archaeological sites and two isolated finds. Allbut three sites are recommended not eligible for listing on the NRHP due to their limited

    research potential beyond current documentation. Previous geomorphological studies

    and site testing along the valley slope ecotone indicated that cultural resources located in

    this area are entirely surficial and of mixed material deposits due to episodic periods of

    eolian and colluvial aggradation and deflation (Whitfield et al. 2007). Numerous

    entrenched drainages now dissect the valley slope ecotone and have undoubtedly become

    entrenched over the last 125 years due to grazing and timber harvesting. Prior to

    entrenchment, these drainages would have redeposited cultural material from overbank

    flooding, particularly near the valley floor terminus of these drainages. Outwash

    boulders are clearly discernible as terminal deposits on the valley floor. Conversely, it

    appears the interfluvial ridges between the upper (southern) portions of the entrenched

    drainages have remained largely stable. However, sediment deposits on these ridges are

    extremely shallow, and are composed of unconsolidated large clast colluvium; the

    cultural material is entirely surficial or near surface in this context. Therefore, with the

    exception of AC 2 of site 5MN9206, all cultural resources are recommended not eligiblefor the NRHP. Ground disturbance associated with installing ground water wells and

    access roads will be designed to avoid cultural resources, where feasible. Isolated finds,

    by definition, are not eligible for inclusion in the NRHP.

    A determination of no historic properties affected, pursuant to 36 CFR 800.5 of the

    NHPA, is recommended for the project area, contingent upon avoidance of all significant

    cultural resources.
