Geologic Map of the Central San Juan Caldera Cluster, Southwestern Colorado by Peter W
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). White arrows show contacts between outflow units. 2006 U.S. Department of the Interior U.S. Geological Survey CONTENTS Geologic setting . 1 Volcanism . 1 Structure . 2 Methods of study . 3 Description of map units . 4 Surficial deposits . 4 Glacial deposits . 4 Postcaldera volcanic rocks . 4 Hinsdale Formation . 4 Los Pinos Formation . 5 Oligocene volcanic rocks . 5 Rocks of the Creede Caldera cycle . 5 Creede Formation . 5 Fisher Dacite . 5 Snowshoe Mountain Tuff . 6 Rocks of the San Luis caldera complex . 7 Rocks of the Nelson Mountain caldera cycle . 7 Rocks of the Cebolla Creek caldera cycle . 9 Rocks of the Rat Creek caldera cycle . 10 Lava flows premonitory(?) to San Luis caldera complex . .11 Rocks of the South River caldera cycle . -

San Juan National Forest
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. -
CODOS – Colorado Dust-On-Snow – WY 2009 Update #1, February 15, 2009
CODOS – Colorado Dust-on-Snow – WY 2009 Update #1, February 15, 2009 Greetings from Silverton, Colorado on the 3-year anniversary of the February 15, 2006 dust-on-snow event that played such a pivotal role in the early and intense snowmelt runoff of Spring 2006. This CODOS Update will kick off the Water Year 2009 series of Updates and Alerts designed to keep you apprised of dust- on-snow conditions in the Colorado mountains. We welcome two new CODOS program participants – Northern Colorado Water Conservation District and Animas-LaPlata Water Conservancy District – to our list of past and ongoing supporters – Colorado River Water Conservation District, Southwestern Water Conservation District, Rio Grande Water Conservation District, Upper Gunnison River Water Conservancy District, Tri-County Water Conservancy District, Denver Water, and Western Water Assessment-CIRES. This season we will issue “Updates” to inform you about observed dust layers in your watersheds, and how they are likely to influence snowmelt timing and rates in the near term, given the National Weather Service’s 7-10 forecast. We will also issue “Alerts” to give you a timely “heads up” about either an imminent or actual dust-on-snow deposition event in progress. Several other key organizations monitoring and forecasting weather, snowpack, and streamflows on your behalf will also receive these products, as a courtesy. As you may know, some Colorado ranges already have a significant dust layer within the snowpack. The photo below taken at our Swamp Angel Study Plot near Red Mountain Pass on January 1 shows, very distinctly, a significant dust layer deposited on December 13, 2008, now deeply buried under 1 meter of snow. -
Decision Memo Monarch Pass U.S. Forest Service San Isabel National Forest Salida Ranger District Chaffee County, Colorado
Decision Memo Monarch Pass U.S. Forest Service San Isabel National Forest Salida Ranger District Chaffee County, Colorado BACKGROUND AND PURPOSE & NEED Background: Beginning in the early 2000’s in the Weminuche Wilderness of southern Colorado, a spruce beetle (Dendroctonus rufipennis) epidemic began expanding north. During stand exam field procedures in 2012, within the Monarch Mountain Ski area, active spruce beetle infestation was discovered on several plots. Further reconnaissance discovered scattered spruce beetle populations in the Monarch Mountain Ski area, Old Monarch Pass and Monarch Park areas. Prior to this time no active spruce beetle infestation had been observed in these areas. Since 2012, spruce beetle activity has increased and is now at epidemic levels across the Monarch Pass area. In some stands, mortality of the mature overstory is approaching 75 percent. In Colorado, spruce beetle has affected over 1.7 million acres since 1996. Figure 1. Example of forest conditions in the Monarch Pass area (early spring 2017). Photo by A. Rudney. — Decision Memo — Page 1 of 23 Figure 2. Example of trees killed by spruce beetle. Photo by A. Rudney. Western balsam bark beetle (Dryocoetes confusus) has been affecting stands within the ski area and across the Monarch Pass area since the early 2000’s. Lodgepole pine (Pinus contorta) forests in the area are at high risk for mountain pine beetle infestation (Dendroctonus ponderosae) due to mature age, tree size and density. In addition, increased snag (dead standing trees) levels within the ski area have exposed visitors to a higher risk of falling trees. The increase in mortality is leading to increased fuel loading and higher risks for firefighters attempting initial or extended attack on wildland fires within the project area. -
