Suitability D-i Tres Rios Field Office Resource Management Plan This page intentionally left blank. D-ii Appendix D – Wild and Scenic Rivers Suitability INTRODUCTION TO WILD AND SCENIC RIVER SUITABILITY Under Section 5 (d)(1) of the Wild and Scenic Rivers Act (WSRA), federal agencies undertaking land management planning are required to assess whether any of the rivers and streams in the planning area would be appropriate for addition to the National Wild and Scenic Rivers System. The process of designating a Wild and Scenic River (WSR) has four steps: 1. The U.S. Forest Service (USFS) and/or Bureau of Land Management (BLM) determine streams that are “eligible,” and what each “classification” is. 2. The USFS/BLM Land and Resource Management Plan (LRMP) determines which streams are “suitable.” 3. The USFS/BLM can choose when to forward “suitable” streams for legislative consideration. 4. Congress can “designate” a WSR. Steps 1 and 2 are the subject of the Final Environmental Impact Statement (FEIS) and LRMP and are discussed below. There is also an alternative process (under Section 2(a)(ii) of the WSRA) in which the state legislators and governor recommend a river and the Secretary of the Interior designates it as a WSR. That process is not considered in the FEIS and LRMP. Eligible Rivers The WSR analysis considered primarily third-order and larger streams located on the San Juan National Forest (SJNF) and Tres Rios Field Office (TRFO). Some smaller order streams for which subject matter experts identified a potential outstanding remarkable value (ORV) were added, so that all values could be evaluated. The list of all streams evaluated is at the end of this WSR appendix. Streams determined to be sufficiently free-flowing (i.e., not impounded by dams or significantly channelized) were analyzed to determine if they had ORVs. In order to be assessed as outstandingly remarkable, a river-related value must be a unique, rare, or exemplary feature that is significant at a comparative regional or national scale. ORVs can be related to scenery, recreation, geology, fish, wildlife, historical, cultural, or other values. Discussions with the Government Water Roundtable from September 2005 to February 2007 were useful in refining the ORV assessment. Members of the Water Roundtable provided information to help develop criteria for determining the significance of values. In addition, the Dolores River Dialogue (DRD) provided

The newly created Hermosa Creek Wilderness and the Hermosa Special Management Area (SMA) are a result of a collaborative effort from a diverse group of local stakeholders that desired to achieve legislative protection of the watershed. The legislation that created the Hermosa Creek Watershed Protection stat es : "The purpose of the Special Man agement Area is to conserve and protect for the benefit of present and future generations the watershed, geological, scientific, recreational, wildlife, riparian, historical, educational, and scenic resources of the Special Management Area." The Hermosa Plan is an amendment to the 2013 San Juan National Forest (SJNF) Land and Resource Management Plan (Forest Plan), and the Recreational and Travel Management analysis and decision will be an integral part of the plan. The Hermosa Plan area is approximately 107, 900 ac res of National Forest land and includes both the SMA and Hermosa Creek Wilderness located in La Plata and San Juan Counties. It is a popular destination for many types of motorized and non -motorized rec reation including: Off Hi ghway Vehicle (OHV) riding, motorbiking, mountain biking, hiking, horseback riding, fishing, hunting, and camping.

  • The Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands
    The Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands David Coblentz Earth and Environmental Sciences Division, Los Alamos National Laboratory, Los Alamos, NM Abstract—While the unique geographic location of the Sky Islands is well recognized as a primary factor for the elevated biodiversity of the region, its unique tectonic history is often overlooked. The mixing of tectonic environments is an important supplement to the mixing of flora and faunal regimes in contributing to the biodiversity of the Madrean Archipelago. The Sky Islands region is located near the actively deforming plate margin of the Western United States that has seen active and diverse tectonics spanning more than 300 million years, many aspects of which are preserved in the present-day geology. This tectonic history has played a fundamental role in the development and nature of the topography, bedrock geology, and soil distribution through the region that in turn are important factors for understanding the biodiversity. Consideration of the geologic and tectonic history of the Sky Islands also provides important insights into the “deep time” factors contributing to present-day biodiversity that fall outside the normal realm of human perception. in the North American Cordillera between the Sierra Madre Introduction Occidental and the Colorado Plateau – Southern Rocky The “Sky Island” region of the Madrean Archipelago (lo- Mountains (figure 1).

    SAN JUAN NATIONAL FOREST Colorado UNITED STATES DEPARTMENT OF AGRICULTURE V 5 FOREST SERVICE t~~/~ Rocky Mountain Region Denver, Colorado Cover Page. — Chimney Rock, San Juan National Forest F406922 UNITED STATES GOVERNMENT PRINTING OFFICE WASHINGTON : 1942 * DEPOSITED BY T,HE UNITED STATES OF AMERICA San Juan National Forest CAN JUAN NATIONAL FOREST is located in the southwestern part of Colorado, south and west of the Continental Divide, and extends, from the headwaters of the Navajo River westward to the La Plata Moun- \ tains. It is named after the San Juan River, the principal river drainage y in this section of the State, which, with its tributaries in Colorado, drains the entire area within the forest. It contains a gross area of 1,444,953 ^ acres, of which 1,255,977 are Government land under Forest Service administration, and 188,976 are State and privately owned. The forest was created by proclamation of President Theodore Roosevelt on June 3, 1905. RICH IN HISTORY The San Juan country records the march of time from prehistoric man through the days of early explorers and the exploits of modern pioneers, each group of which has left its mark upon the land. The earliest signs of habitation by man were left by the cliff and mound dwellers. Currently with or following this period the inhabitants were the ancestors of the present tribes of Indians, the Navajos and the Utes. After the middle of the eighteenth century the early Spanish explorers and traders made their advent into this section of the new world in increasing numbers.

  • Animas River
    2013 River Protection Workgroup for the Animas River Final Report May 2013 an initiative of the River Protection Workgroup http://ocs.fortlewis.edu/riverprotection The River Protection Workgroup (RPW) project was formed as an outgrowth of discussions starting in 2006 among various regional water planning and resource protection organizations where a need became apparent for a collaborative process to select long-term, reliable, federal and/or state and/or other measures to protect the identified values of regional streams while allowing water development to continue. A project steering committee formed and then met for over a year to get organized, design the process model, and begin to work at the community level for these five river/stream segments: Hermosa Creek; upper Animas River and Mineral and South Mineral Creeks; upper San Juan River - East and West Forks; Vallecito Creek/Pine River; and the Piedra River. The first step for each river and stream segment was to organize a meeting at the community level to see if there was interest in forming a public workgroup – one that would entail learning, discussions and issuing a final report of findings, agreements and conclusions. The River Protection Workgroup for the Animas kicked off in June of 2011 and concluded its work in May 2013. Each of the RPW Workgroups’ reports can be found on the project Web site along with meeting notes, handouts, maps, and more: http://ocs.fortlewis.edu/riverprotection/ For more information about the RPW, please refer to Attachment A which gives detailed

Denison, "·ho was away on a trip, saying: "vVill you buy me a pony? I don't want a Shetland pony because it is cross. I want an Indian pony. I have heard about them." Little did that lad dream that some day he would be riding a western Indian pony on a real round-up for his own cattle. But later, as a young man, he went in search of health and did ranch in Wyoming and Colorado. Toda)· a portrait1 of \Villiam Denison, from the old family homestead in Vermont, has a place of honor in the Public Library in Steamboat Springs. The William Denison Library, established in 1887 by the Denison family, as a memorial to " \Villie" Denison, was, according to an Old Timer, "the pride of Steamboat when it was established. It was a rallying point for the unfolding and intelligence of a struggling little settlement, and when the final total is cast up it will fill a higher niche in the archives of good accomplished than many of the magnificent piles of stone and marble that Carnegie has scattered over the land.' ' 2 From pioneer clays, members of the Denison family have been prominent in many phases of Colorado life.
