GEOGRAPHY OF NITRATE AND SULFATE ATMOSPHERIC WET DEPOSITION IN THE SOUTHERN ROCKY MOUNTAINS by IVAN GUILLERMO VALLES B.S., Colorado State University—Pueblo, 2005 A thesis submitted to the Graduate Faculty of the University of Colorado Colorado Springs in partial fulfillment of the requirements for the degree of Master of Arts Department of Geography and Environmental Studies 2018 © 2018 IVAN GUILLERMO VALLES ALL RIGHTS RESERVED ii This thesis for the Master of Arts degree by Ivan Guillermo Valles has been approved for the Department of Geography of Environmental Studies by Curtis D. Holder, Chair Steve Jennings Brandon Vogt Date January 27, 2018 iii Valles, Ivan Guillermo (M.A., Applied Geography) Geography of Nitrate and Sulfate Atmospheric Wet Deposition in the Southern Rocky Mountains Thesis directed by Professor Curtis Holder. ABSTRACT Data from the National Atmospheric Deposition Program’s National Trends Network, the United States Geological Survey’s Rocky Mountain Regional Snowpack Chemistry Program and the United States Environmental Protection Agency’s Air Markets Program were analyzed to identify spatial relationships amongst atmospheric wet deposition concentrations of nitrate and sulfate. The analysis relates atmospheric wet deposition, commonly known as acid rain, to two distinct variables—as a function of elevation and also as a function of proximity to major regional electricity generating stations. This study focuses on the Southern Rocky Mountain region of the United States, and integrates depositional and emissions point-source data from Arizona, Colorado, New Mexico, Utah, and Wyoming. Previous studies have identified wide-ranging adverse effects upon terrestrial and aquatic ecosystems such as nitrogen saturation, changes in plant biodiversity, and soil nutrient cycling where atmospheric wet deposition is the suspected primary means of pollutant transport and delivery. -

The Mystery of Lake San Cristobal: a Natural Lake No More?
Reflections: The mystery of Lake San Cristobal: A natural lake no more? By: Lyn Lampert and Camille Richard, Chair and Coordinator, respectively, of the Lake Fork Watershed Stakeholders, Lake City, CO, July, 2008. Like a captivating Agatha Christie novel, Lake San Cristobal is a beautiful mystery. The more one learns about this centerpiece of Hinsdale County, the more unanswered questions one finds. Somehow, it is uniquely refreshing, though, in this age of quantification and precise explanation, to find something that defies complete understanding and description. Lake San Cristobal is one such place, whose manifold mysteries only add to its enchanting allure. The first written record of the glories of this body of water was compiled by a small Army expedition doing the “Reconnaissance of the Ute Country” in 1873. This expedition, led by Lt. E. H. Ruffner, produced the first accurate descriptions of many parts of the San Juan for the outside world. The expedition approached the lake from upstream after doing work in the Baker’s Park (now Silverton) district. As beautiful as the lake is today, it must have been an incredible gem in 1873, without roads, power lines or habitation. Indeed, Ruffner’s description speaks in glowing terms, praising its islands and coves and abundance of ducks and coots. The origin of its name remains a mystery. “San Cristobal” is obviously Spanish in derivation, and many Latin American places are named for Saint Christopher. Saint Christopher was a semi-mythical character from the 3rd century, and today is popularly known as the Patron Saint of Travelers. Frank Hall in his authoritative 1895 “History of Colorado” claims the name of ‘Lake Chrystobal’ was given by US engineer corps staff encamped at the lake during the Ute Country reconnaissance, inspired by a poem of Tennyson. -

COLORADO CONTINENTAL DIVIDE TRAIL COALITION VISIT COLORADO! Day & Overnight Hikes on the Continental Divide Trail
CONTINENTAL DIVIDE NATIONAL SCENIC TRAIL DAY & OVERNIGHT HIKES: COLORADO CONTINENTAL DIVIDE TRAIL COALITION VISIT COLORADO! Day & Overnight Hikes on the Continental Divide Trail THE CENTENNIAL STATE The Colorado Rockies are the quintessential CDT experience! The CDT traverses 800 miles of these majestic and challenging peaks dotted with abandoned homesteads and ghost towns, and crosses the ancestral lands of the Ute, Eastern Shoshone, and Cheyenne peoples. The CDT winds through some of Colorado’s most incredible landscapes: the spectacular alpine tundra of the South San Juan, Weminuche, and La Garita Wildernesses where the CDT remains at or above 11,000 feet for nearly 70 miles; remnants of the late 1800’s ghost town of Hancock that served the Alpine Tunnel; the awe-inspiring Collegiate Peaks near Leadville, the highest incorporated city in America; geologic oddities like The Window, Knife Edge, and Devil’s Thumb; the towering 14,270 foot Grays Peak – the highest point on the CDT; Rocky Mountain National Park with its rugged snow-capped skyline; the remote Never Summer Wilderness; and the broad valleys and numerous glacial lakes and cirques of the Mount Zirkel Wilderness. You might also encounter moose, mountain goats, bighorn sheep, marmots, and pika on the CDT in Colorado. In this guide, you’ll find Colorado’s best day and overnight hikes on the CDT, organized south to north. ELEVATION: The average elevation of the CDT in Colorado is 10,978 ft, and all of the hikes listed in this guide begin at elevations above 8,000 ft. Remember to bring plenty of water, sun protection, and extra food, and know that a hike at elevation will likely be more challenging than the same distance hike at sea level. -

Papilio Series) 2006
(NEW April 28 PAPILIO SERIES) 2006 TAXONOMIC STUDIES AND NEW TAXA OF NORTH AMERICAN BUTTERFLIES by James A. Scott (also editor), Michael S. Fisher, Norbert G. Kondla, Steve Kohler, Crispin S. Guppy, Stephen M. Spomer, and B. Chris Schmidt Abstract. New diversity is reported and discussed among North American butterflies. Several dozen new taxa are named. A new "sibling" species has been found to occur throughout the Rocky Mts., introducing a new butterfly species to most states in western U.S. and to southern Alberta and BC. Several taxa of Colias, Euphydryas, Lycaena, and Plebejus are raised to species status. Many nam.e changes are made, and many taxa are switched between species to create several dozen new combinations. The relevance of species concepts to difficult groups of butterflies is explored. Introduction This paper consists of miscellaneous taxonomic studies on North American butterflies, some in the northeast, but mostly in the west. Most of the diversity of butterfly fauna in North America is in the western mountainous areas, where the human population is lower, so it has taken longer to study western butterflies, and a lot more study is needed. We have made new findings on many wes.tern butterflies, and this progress is reported below. And Scott recently moved his collection out of old dermestid-infested drawers into fine very-tight ones that those beetles cannot enter, and in the process of resorting them found a dozen unnamed subspecies, which are named below. As we study our butterflies and learn more and more about them, a disturbing pattern has emerged. -
