Volume III D-ii Appendix D – Wild and Scenic Rivers Suitability Final Environmental Impact Statement 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

    Geologic Map of the Central San Juan Caldera Cluster, Southwestern Colorado By Peter W. Lipman Pamphlet to accompany Geologic Investigations Series I–2799 dacite Ceobolla Creek Tuff Nelson Mountain Tuff, rhyolite Rat Creek Tuff, dacite Cebolla Creek Tuff Rat Creek Tuff, rhyolite Wheeler Geologic Monument (Half Moon Pass quadrangle) provides exceptional exposures of three outflow tuff sheets erupted from the San Luis caldera complex. Lowest sheet is Rat Creek Tuff, which is nonwelded throughout but grades upward from light-tan rhyolite (~74% SiO2) into pale brown dacite (~66% SiO2) that contains sparse dark-brown andesitic scoria. Distinctive hornblende-rich middle Cebolla Creek Tuff contains basal surge beds, overlain by vitrophyre of uniform mafic dacite that becomes less welded upward. Uppermost Nelson Mountain Tuff consists of nonwelded to weakly welded, crystal-poor rhyolite, which grades upward to a densely welded caprock of crystal-rich dacite (~68% SiO2).

  • 2.2 Mile, 1372' Lizard Head Wilderness
    June 2 - 4, 2007 Lizard Head 11583’, north 37° 49’ 17”, west 107° 57’ 11” 2.2 mile, 1372’ Lizard Head Wilderness, San Juan National Forest, Dolores County, Colorado The Lizard Head looks to the sky from it’s 12000’ perch twelve miles almost due south of Sawpit, Colorado. You can’t drive there, but if you drive on CO-145 south for 21.6 miles from Sawpit, you can park at the trailhead for Lizard Head Pass Trail, and can see the 13113’ spire. But you still need to walk about four miles in the San Miguel Mountains to touch the old rocky spire. Getting to the top, however, is for experts. One internet climbing site says it’s not safe to climb anymore because it’s rock is rotting and unstable. Another site calls the volcanic pinnacle the state's most dangerous climb. Another calls Lizard Head peak a recommended conditioning or training climb in preparation for other climbs in the area, such as the Mt. Wilson – El Diente Traverse, only three miles west. At a little after 10 am on Saturday morning Kent and I met at the Cross Mountain Trail Head parking lot, about two miles south of Lizard Head Pass on CO-145. One empty vehicle was parked at the trailhead. Another, occupied by a couple of trail runners who had jogged down the trail almost as soon as I arrived, had left a bit before Kent arrived. A cowboy and his horse and dog pulled in while we were getting ready, saddled up and was off on a day ride to Navajo Lake, a popular destination at 11154’ in the valley west of Mt.

(SME) was retained by Navajo Nation Oil and Gas (NNOGC) to procure Clean Water Act (CWA) Section 404 and Section 401 authorizations for the above- referenced project. The purpose of the NNOGC Mancos Wash project is to address the potential hazard along the Running Horse Pipeline (RHP) where the existing pipeline crosses the Mancos River at MP 29. The existing RHP has approximately 10-15 feet (ft) of pipeline exposure in the Mancos River at this location. We request CWA Section 404 authorization for this crossing pursuant to Nationwide Permit (NWP) 3 for Maintenance and NWP 43 for Stormwater Management Facilities. Pre- Construction Notification (PCN) to the U.S. Army Corps of Engineers (USACE) is required. On March 3, 2017, the Ute Mountain Ute Tribe denied CWA Section 401 Water Quality Certification (WQC) for their Tribal lands in Colorado, New Mexico, and Utah.

Pecora, Director For sale by the Superintendent of Documents, U.S. Government Printing Office Washington, D.C. 20402 STUDIES RELATED TO WILDERNESS PRIMITIVE AREAS The Wilderness Act (Public Law 88-577, Sept. 3, 1964) and the Conference Report on Senate bill 4, 88th Congress, direct the U.S. Geological Survey and the U.S. Bureau of Mines to make mineral surveys of wilderness and primi­ tive areas. Areas officially designated as "wilderness," "wild," or "canoe" when the act was passed were incor­ porated into the National Wilderness Preservation Sys­ tem. Areas classed as "primitive" were not included in the Wilderness System, but the act provided that each primitive area should be studied for its suitability for incorporation into the Wilderness System. The mineral surveys constitute one aspect of the suitability studies. This bulletin reports the results of a mineral survey of the San Juan and the Upper Rio Grande primitive areas, Colorado. The area discussed in the report corresponds to the area under consideration for wilderness status.
