Wisconsin Street, Suite G Gunnison, Colorado 81230 Submitted to— History Colorado 1200 Broadway Denver, Colorado 80203 Prepared by ERO Resources Corporation 1842 Clarkson Street Denver, Colorado 80218 (303) 830-1188 Written by Abigail Sanocki Jonathan Hedlund Prepared under the supervision of Sean Larmore, Principal Investigator History Colorado Project #CO-15-018 ERO Project No. 6503 August 2016 ERO Resources Corp. 1015 ½ Main Ave. Durango, CO 81301 970.422.2136 www.eroresources.com ABSTRACT The Gunnison County Historic Preservation Commission (HPC) contracted ERO Resources Corporation (ERO) to prepare a county-wide historic resource survey plan. ERO developed the plan using funds from the Certified Local Government Subgrant Program administered by History Colorado (Project #CO-15-08). The survey plan provides prioritization recommendations for future intensive or reconnaissance survey efforts to identify and document cultural resources in Gunnison County. The purpose of a survey plan is to identify areas where survey may help the HPC establish priorities for future preservation, nominations, and public outreach as derived through the information gained during a survey. The survey plan includes recommendations for future reconnaissance or intensive surveys of buildings, structures, and archaeological resources on county-, city-, and privately- owned land. The survey recommendations provided are prioritized based on public input, the extent of previously conducted work in the county, the current condition of resources that reflect important themes in the county’s past, and the goals and powers of the HPC. In addition to providing guidance for planning future cultural resource surveys, this document includes an overview of the previously conducted survey and documentation work in Gunnison County and a thematic historical overview of the county’s history. The historical overview provides general guidance for interpreting the history and determining the significance of historic properties associated with the identified themes.

The plan was developed using funds from the Certified Local Government (CLG) Subgrant Program (Project #CO-15-08). It provides prioritization recommendations for future intensive or reconnaissance survey efforts to identify and document historic resources (i.e., sites or properties containing archaeological resources, structures, and/or buildings that are related to significant events, themes or people from the past, significant methods of construction or architectural design, or have the potential to yield additional information about the history of the region); survey types are defined in the Field Reconnaissance section of this report. The purpose of a survey plan is to identify areas where survey may help the HPC establish priorities for future preservation, nominations, and public outreach as derived through information gained during a survey. The surveys could also assist the HPC’s efforts to work proactively with the other county commissions and landowners for preservation and during planning review for new developments in Gunnison County. The survey plan includes recommendations for future reconnaissance or intensive surveys of buildings, structures, and archaeological resources on Gunnison County, municipal, and privately owned land. Survey recommendations are prioritized based on public input, the extent of previously conducted work in the region, the current condition of resources that represent important themes in the county’s past, and the goals and powers of the HPC. In addition to providing guidance for planning future cultural resource surveys, this document also includes an overview of the previously conducted survey and documentation work in the county and a selective historical overview that identifies important themes and periods of significance.

Five interim Task Memoranda have been submitted previously, each reporting in detail on certain aspects of the study. A Final Report which discusses the study in a more detailed manner is submitted under separate cover. The objective of this study was to identify and evaluate water resource management plans to enhance the water-based economy of the Study Area in an environmentally sound manner. Both structural and non-structural components have been examined, evaluated and utilized to formulate alternative plans which would meet in-basin needs. A recommended plan has been identified which meets the study objective. Non-structural measures related municipal industrial sector were found to have little potential for saving water in the context of this basin-wide study because the total consumptive use in this sector is less than two percent of the total consumptive use in the entire study area at present.

  • Field Trip to Northern San Juan Volcanic Field
    ,- ' FIELD TRIP TO NORTHERN SAN JUAN VOLCANIC FIELD Days 2-3: Cochetopa Park, La Garita, San Luis, and Lake City calderas P.W. Lipman, for Colorado Scientific Society, Sept. 20-21, 2003 GEOLOGIC SETTING Andesitic to rhyolitic volcanic rocks of the central San Juan volcanic field, along with associated epithermal ores, have been studied intermittently since early in the twentieth century (Emmons and Larsen, 1913; Cross and Larsen, 1935; Larsen and Cross, 1956), culminating with the detailed study of the Creede mining district by Steven and Ratte (1965) and regional field and volcanological studies (Lipman and others, 1970; Steven and others, 1974; Steven and Lipman, 1976). While much had previously been learned about the evolution of several complex caldera clusters from 3 which at least 22 major ash-flow sheets (each 150-5,000 km ) were erupted at 30-26 Ma, recent mapping and other research initiated in support of the Creede Scientific Drilling Project (Bethke and Lipman, 1987; Bethke and Hay, 2000; Lipman, 2000) has provided major new insights for the regional stratigraphic sequence, duration of volcanism, eruptive processes, magmatic evolution, and regional structure in the central part of the volcanic field. In-progress studies,to be reviewed during this trip, are focusing on the enigmatic Cochetopa Park caldera and little-studied volcanic evolution of the northeasternSan Juan Mountains, where central San Juan units overlap older tuff sheets from caldera sources in the Sawatch Range farther to the northeast. Volcanism The San Juan Mountains are the largest erosional remnant of a composite volcanic field (Fig. 1) that covered much of the southern Rocky Mountains in middle Tertiary time (Steven, 1975).

  • Request for Qualifications
    REQUEST FOR QUALIFICATIONS Agricultural Engineering & Irrigation Planning Support Services On behalf of Upper Gunnison River Water Conservancy District November 18, 2020 1 The Upper Gunnison River Water Conservancy District (District) is pleased to solicit this request for qualifications for a consultant or consultant team to assist the District with agricultural irrigation planning and engineering services (work issued on a Task Order and as- needed basis) related to the Upper Gunnison Basin Irrigation Assessment and Optimization Project. The District anticipates consultant support throughout all seven watersheds as described in this document, with the greatest work effort occurring in the Ohio, East and Tomichi Creek sub- basins (Figure 1). 1.0 Background The District was established in 1959 by a vote of the taxpayers pursuant to the Water Conservancy Act to conserve, protect, and defend the waters within the Upper Gunnison River Basin. The District is governed by a board of eleven directors and staffed by its General Manager, General Counsel, Office Manager, Water Resource Specialist and Administrative Assistant. Our mission is to be an active leader in all issues affecting the water resources of the Upper Gunnison River Basin. The District website provides additional detail and can be found at: www.ugrwcd.org The Upper Gunnison River watershed is geographically located in west-central Colorado in the headwaters of the Gunnison River Basin, upstream of Blue Mesa Reservoir. The mainstem of the Gunnison River which forms at the confluence of the East and Taylor Rivers in Almont, picks up other tributaries on its way into Blue Mesa Reservoir. There are seven tributary mountain watersheds that make up the Upper Gunnison River Basin including Ohio Creek, East River (includes the Slate River), Taylor River, Gunnison River, Tomichi Creek (includes Quartz Creek), Cochetopa Creek, and the Lake Fork of the Gunnison (Figure 1).
