STATEMENT OF WORK

2024 Cultural Resources Inventory of Upper Cahone Canyon in Dolores County, Colorado

INTRODUCTION

This Statement of Work is for:

A Class III archaeological block inventory of 160 acres in upper Cahone Canyon on the Bureau of Land Management (BLM), Tres Rios Field Office (TRFO), in Dolores County Colorado. The tasks involved include a records search, fieldwork, analysis, report preparation, documentation of cultural resources on OAHP forms, and production of associated GIS data. This cultural resource work will be conducted under Section 110 of the National Historic Preservation Act.

The survey area can be accessed by CR S and private property (2-wheel drive low clearance), however cross-country foot travel will be necessary within the survey block because there are no travel routes within the BLM parcel. The topography and vegetation in the survey area is variable.

The general location of the survey area is due west of Cahone Colorado, Township and Range 39N 18W, Section 16 (northern ½) and is located on the Cahone 7.5 USGS 24:000 topographical quadrangle map. Shapefiles of the survey area are available upon request. Contact Brian Yaquinto: 970-749-9583 (byaquinto@blm.gov).

Project Background:

The survey will be conducted to identify cultural resources as part of the TRFO FY 24 Section110 program. A grazing impacts assessment form (see attachment 2) will be completed for each site with noted impacts from livestock grazing.

Previous Inventory and Recorded Cultural Resources

A disclosure of prior surveys and recorded cultural resources in the survey areas is provided below with the intent of assisting prospective bidders with more specific inventory information about areas adjacent to the project area. While it is frequently the case that similar site types can be expected in the project area if it is a similar landscape, this is not always true. Prospective bidders should not assume that information is anything more than a general description of what is known within the project area based upon information in the archaeological records at the BLM TRFO and the Colorado OAHP COMPASS database. It is the bidder’s responsibility to thoroughly research their bids.

No previous archaeological survey has been conducted on this isolated tract of BLM; however, the parcel is likely to contain habitation sites and camps, quarries, and sheltered camps/architecture mailto:byaquinto@blm.gov associated with the Pueblo I and Pueblo II occupation of the area. Two sites have been previously recorded in the project area.

Previous Inventory No inventories have been completed in the project area.

Project Objectives

A Class III (intensive level) inventory of 160 acres of BLM land. (See attachment 1).

To accomplish these objectives

• The Contractor and any subcontractors must be able to or hold an active BLM-CO Cultural Resource Use Permit (CRUP) and the work must be conducted by personnel under that permit qualified to work on the Tres Rios Field Office. All CRUP permit stipulations will be followed.

• This Statement of Work is for a fixed price contract. The Contractor shall furnish all labor, supervision, transportation, travel, services, facilities, materials, and supplies necessary for the performance of all aspects of the tasks described herein. All contractor costs are to be included in the contractor’s bid.

• No monetary contract modifications will be provided for unanticipated site density or logistical complexity not considered by the contractor in their bid.

PROCUREMENT DELIVERABLES BY TASKS

Task 1: Pre-field File Search and Records Review Due 3 weeks after contract award

• Given the lack of previous inventory and recorded cultural resources, the TRFO portion of the records search will entail the consultant notifying the BLM archaeologist via email, once the contract has been awarded, who will provide the consultant with a shapefile and site forms of the two previously recorded sites in the survey area. This notification should be at least 5 days prior to the start of the fieldwork and is recommended to occur alongside the submission of the field work authorization.

• Using the OAHP Compass database, and a review of the GLO historic maps, consultants must review at a minimum the results of previous work within one mile radius of the project survey area boundary to create a background and interpretive context for the appropriate sections of the Inventory Report. GLO historic maps are expected to be accessed online prior to completing a files search at the BLM office. Additional historic literature review may be warranted depending on the files search findings, particularly in the case of historic linear resources.

Task 2: Fieldwork Due 8 weeks after completion of Task 1

Conduct an intensive level cultural resource inventory within the specified survey area to locate and record new sites and isolated finds. Previously recorded sites are not required to be revisited.

Class III Cultural Resource Inventory

• Fieldwork authorization: A fieldwork authorization must be submitted to the field office archaeologist at least 5 days prior to start of fieldwork and should be submitted via email (preferred).

• The task will be conducted under the provisions of the BLM Colorado Cultural Resource Use Permit and will conform to guidelines contained in the most current versions of the BLM Colorado Handbook of Guidelines and Procedures for Inventory, Evaluation, and Mitigation of Cultural Resources, the BLM-Colorado Digital Data Specifications Guide (revised 2022), the requirements in this statement of work, and the OAHP Colorado Cultural Resource Survey Manual.

• The Contractor must locate the boundaries of the survey area prior to commencement of the survey. Use of GPS units, benchmarks, 7.5-minute topographic maps, aerial photographs (where available), roadways and other landscape features, if needed, is required to ensure ground control and confidence in the inventory area and in the location of cultural resources.

• An intensive pedestrian survey, transect intervals not exceeding 15 meters, within the block survey area will be conducted to identify and record all cultural resources. Actual ground examination should result in the identification and recording of all cultural resources observable on the surface and in exposed subsurface profiles.

• Reconnaissance level inventory will occur on any slopes greater than 30%, particularly in areas where rock overhangs are present. Sheltered architecture and camps are likely present in the survey area in addition to rock art.

• Each field crew must be supervised in the field by a qualified crew chief and/or field director listed on the CRUP. A crew chief or field director must be on-site at all times.

• The Contractor must notify the Contract Officer’s Representative (COR) or Project Inspector by telephone and with written confirmation immediately upon the discovery of human remains, funerary objects, sacred objects, or objects of cultural patrimony (as defined in 43 CFR 10.2) and must immediately stop any activities connected with such discovery and make a reasonable effort to protect the discovered remains or objects.

Recording and Evaluation of Cultural Resources

• The Contractor must record each cultural resource identified following the BLM Colorado Handbook of Guidelines and Procedures for Inventory, Evaluation, and Mitigation of Cultural Resources, the BLM-Colorado Digital Data Specifications Guide (revised 2022), the requirements in this statement of work, and the OAHP Colorado Cultural Resource Survey Manual

• The full extent of sites should be intensively recorded, even if sites extend outside the survey area (record portions of sites outside survey areas). If a site extends onto private property, the contractor will attempt to obtain landowner permission to record the portion of the site on private property. If landowner permission can’t be obtained, only the portion of the site on BLM will be recorded. As the survey area in this SOW borders private property, the contractor should budget for the possibility of additional acres of site recording on non-BLM surface.

• To refine or complete National Register eligibility recommendations, evaluative testing (soil probing, trowel testing, auger testing, or shovel testing) will be conducted at all sites where the contractor is unable to determine site eligibility based on surface evidence. This evaluative testing during field recording should be used to determine the potential for subsurface cultural deposits and the site boundary, as needed. Evaluative testing should not exceed three (3) square meters of site surface. Testing locations should also be shown on the site map. The level of testing should not be conducted in a manner that impacts or destroys information that contributes to the sites’ eligibility. Criteria used to determine properties potentially eligible for the NRHP must be substantive, objective, and stated in the report.

• Potentially eligible sites will be tested to determine site depth potential, integrity and eligibility wherever possible. The “Need Data” determination should be applied sparingly and only in those cases where both surface evidence and limited testing yield ambiguous results.

• Scaled site maps will include detailed drawings of site features, structures, locations of diagnostic artifacts, artifact concentrations, boundary, topography of the site area, as well as nearby developments or distinctive landforms (roads, power lines, well pads, canyon rims, etc.).

Locations of disturbance and the nature of disturbance will be indicated on the site map. The location of the site tag will be indicated on the site map. Any mapped item not specifically described in the map key will be individually labeled on the map.

• A current assessment of site condition will be made for each site in terms of impacts from natural processes (erosion), human processes (looting/vandalism, commercial development, recreational use-motorized or other, chaining), or livestock impacts, as per OAHP management data form items 33, 34, and 35.

• A GPS unit will be used to record precise site boundaries and isolated find centroids. Data collected by GPS must meet a ±5 m. accuracy standard.

• High quality digital images (300 dpi or highest resolution setting) will be taken for use with the site forms. One site overview photo is required. Photos will be taken for unusual or diagnostic isolated finds.

• Artifact collection is not authorized. In-field ceramic and lithic analysis necessary to determine site function and chronology will be completed using current standard published typologies (see below). In the event a rare or unique artifact(s) is found the TRFO archaeologist is to be contacted who will advise the contractor on how to proceed.

• Lithic materials will be identified to include the material type, the debitage type (core, primary, secondary, tertiary, angular debris), or the tool type. Diagnostic projectile points will be drawn and photographed and included with the site documentation. Chapter 8 of the “Crow Canyon Archaeological Center Laboratory Manual, Version 1,” (Ortman et al 2005) is a recommended reference for material type identification.

Task 2: Draft Report and Site Forms Due 5 weeks after completion of fieldwork

• A single digital copy of the draft report, site, and isolated find forms will be submitted to the

COR.

• The report, site, and isolated find forms must include the BLM and SHPO report numbers (obtain from COR).

• The draft final report will include a detailed description and evaluation of all sites visited during the survey, recommendations on National Register eligibility, a discussion of site impacts observed, and site management recommendations. The evaluations should be made in the context of previous investigations and findings in the general area, and research questions for the region. All sites brought forward as “Need Data” will include a detailed discussion of how field testing was conducted and why field testing was inconclusive and specific recommendations for additional evaluative testing to determine eligibility. The site management recommendations must consider the current site condition based on disturbances observed while conducting the field work.

• Sites will be displayed on maps as polygons (site boundaries rather than site centroids). Site maps will include the following citation: Disclosure of site locations prohibited (43 CFR 7.18).

• All site forms, including site revisit forms, must have at a minimum of one photograph showing the general site location with a horizon.

• Cultural resources will be recorded on the appropriate OAHP forms, following OAHP form instruction and guidance. A TRFO Grazing Impact Site Evaluation Form will be completed for each site in the survey areas (both newly and previously recorded).

• Site, isolated find, and survey GIS data (shapefiles) that meet the current BLM-Colorado Digital

Data Specifications Guide will be electronically submitted using a secure platform. Do not use generic file-sharing sites such as Dropbox, Google Drive, etc. If it is unfeasible to provide the electronic data using online file sharing, the BLM will accept emails, and encrypted USB flash drives, but will no longer accept CDs, unless specifically requested by the BLM archaeologist.

BLM Draft Report Review Due 3 weeks after receipt of draft report

• The BLM will submit draft report review comments and/or corrections to the contractor, which must be addressed in the final report.

Task 3: Final Report and Site Forms Due 3 weeks after receipt of BLM draft report comments

• One hard copy of the final report, site, and isolated find forms addressing all changes and corrections identified from the draft report review will be submitted to the project inspector.

Digital copies of the final report, site and isolated find forms, photos, and shapefiles of site, isolated find, and survey area locations that meet the current BLM-Colorado Digital Data Specifications Guide will also be submitted to the project inspector electronically using a secure platform.

• Hard copy site forms are to be separate from the report (do not bind the report and site forms together).

• The BLM retains ownership of, and all rights to, all artifacts collected, records, data, maps, drawings, photographs, samples, artifacts, GIS products, automated data bases, or other products.

These items cannot be used by the Contractor without written permission from the BLM.

BLM Final Report Review Due 10 days after receipt of final report

• Upon receipt of the final report the COR shall have 10 calendar days to review the final report for acceptance or resubmission. If any revisions are needed, the contractor will have 10 calendar days from submission of final comments to resubmit the final report.

COORDINATION

• The Contractor must be highly flexible and able to adapt to changing circumstances. Close coordination with the CO, COR, or Project Inspector (if assigned to the contract) will be necessary to meet contract deadlines. The Contractor must be able to quickly mobilize to execute assigned tasks within the SOW time frames.

• The Contractor shall be responsible for obtaining and coordinating any access needed across private lands for the purpose of conducting work under this contract, contact information will be provided. The Contractor shall advise the COR or Project Inspector within one (1) working day of any access restriction which would significantly delay progress.

• Any unanticipated problems which may delay the Contractor’s work schedule must be reported immediately to the COR or Project Inspector.

• During the course of the project, reasonable precautions will be taken to avoid the disclosure of site locations to all but authorized personnel. In addition, field personnel will be required to keep all motorized vehicles on existing roads and trails.

PROGRAM MANAGEMENT AND CONTROL REQUIREMENTS

• Work performed under this contract shall be monitored according to contract specifications, provisions, and the Contractor's proposal. The Technical Proposal for this RFQ shall thoroughly discuss cost and schedule control as well as quality control.

• Cost and Schedule Control: Adherence to costs and schedules contained in the award shall be closely monitored by the contractor to ensure task deadlines are met.

• Quality Control: Control over the technical quality of all work and deliverables shall be closely monitored by the Contractor to assure required BLM and other professional standards are met.

SUBCONTRACTING

• Any anticipated use of subcontractors must be included in bid proposals, along with the materials requested in the non-cost evaluation factors, specific to the subcontractor.

• The subcontracted firm must currently hold a valid BLM Colorado cultural resource use permit (CRUP), or the principal investigator and crew chief(s) of the subcontracted firm must be listed on the prime contractor’s permit. The CRUP must indicate the principal investigator and crew chief(s) can work on the Tres Rios Field Office (or the San Juan Public Lands).
