An Environmental History of the Middle Rio Grande Basin
United States Department of From the Rio to the Sierra: Agriculture Forest Service An Environmental History of Rocky Mountain Research Station the Middle Rio Grande Basin Fort Collins, Colorado 80526 General Technical Report RMRS-GTR-5 Dan Scurlock i Scurlock, Dan. 1998. From the rio to the sierra: An environmental history of the Middle Rio Grande Basin. General Technical Report RMRS-GTR-5. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 440 p. Abstract Various human groups have greatly affected the processes and evolution of Middle Rio Grande Basin ecosystems, especially riparian zones, from A.D. 1540 to the present. Overgrazing, clear-cutting, irrigation farming, fire suppression, intensive hunting, and introduction of exotic plants have combined with droughts and floods to bring about environmental and associated cultural changes in the Basin. As a result of these changes, public laws were passed and agencies created to rectify or mitigate various environmental problems in the region. Although restoration and remedial programs have improved the overall “health” of Basin ecosystems, most old and new environmental problems persist.

Holocene Tephras in Lake Cores from Northern British Columbia, Canada
935 Holocene tephras in lake cores from northern British Columbia, Canada Thomas R. Lakeman, John J. Clague, Brian Menounos, Gerald D. Osborn, Britta J.L. Jensen, and Duane G. Froese Abstract: Sediment cores recovered from alpine and subalpine lakes up to 250 km apart in northern British Columbia con- tain five previously unrecognized tephras. Two black phonolitic tephras, each 5–10 mm thick, occur within 2–4 cm of each other in basal sediments from seven lakes in the Finlay River – Dease Lake area. The upper and lower Finlay tephras are slightly older than 10 220 – 10 560 cal year B.P. and likely originate from two closely spaced eruptions of one or two large volcanoes in the northern Cordilleran volcanic province. The Finlay tephras occur at the transition between deglacial sediments and organic-rich postglacial mud in the lake cores and, therefore, closely delimit the termination of the Fraser Glaciation in northern British Columbia. Sediments in Bob Quinn Lake, which lies on the east edge of the northern Coast Mountains, contain two black tephras that differ in age and composition from the Finlay tephras. The lower Bob Quinn tephra is 3–4 mm thick, basaltic in composition, and is derived from an eruption in the Iskut River volcanic field about 9400 cal years ago. The upper Bob Quinn tephra is 12 mm thick, trachytic in composition, and probably 7000–8000 cal years old. A fifth tephra occurs as a cryptotephra near the top of two cores from the Finlay River area and is correlated to the east lobe of the White River tephra (ca. -
Personal Recollections of Early Denver
Personal Recollections of Early Denver .J OSEPII EMERSOX S11nTn* Recollections, like everything else, must have a beginning, and my first memory of early Denver has to do with a Fourth of .July Christmas. It has remained vivid, unforgettable, undoubtedly because of th<:' successive shocks to the sensitive ear drums of a small child. Tt was prior to the Chinese riot of 1880 and the large Chinatown of the city, extending from Sixteenth along vVazee and Vlynkoop streets and directly in the rear of the American House for seYeral blocks, was a busy mart, a growth of the steady immi gration of the "Celestials" to Colorado, where thousands had been, and still were, employed in placer mining around Central City, at Fairplay, Tarryall, California Gulch, and other gold camps. Chinatmn1 was their suppl~' source. Here \Yere silk and clothing shops, stores of exotic atmosphere with shelves crowded with im ports, fine tea, spices, drugs, and foods from China, tapestries, fans, laces, and there were many laundries. Underground floors were tunnels leading to burrows and the larger rooms where Nepen- 1heized sleepers lay in bunks, the air sticky and sweet with the fumes of opium. 'l'he steam laundry hadn't come, and the Chinese had a monop oly on laundering. 'l'o homes all over the city trotted the tireless, affable, pig-tailed little yellow men in their blue-black tunics, flap ping trousers and felt white-soled slippers, delivering newspaper wrapped bundles. We " ·ere living at Coffield 's ''family boarding house,'' a spacious two-story verandahed frame residence where the Colorado National Bank now stands at Seventeenth and Champa streets. -

Fire History in the Taos Valley Watersheds, New Mexico, USA
fire Article Surface Fire to Crown Fire: Fire History in the Taos Valley Watersheds, New Mexico, USA Lane B. Johnson 1 and Ellis Q. Margolis 2,* 1 University of Minnesota, Cloquet Forestry Center, 175 University Drive, Cloquet, MN 55720, USA; [email protected] 2 U. S. Geological Survey, Fort Collins Science Center, New Mexico Landscapes Field Station, 301 Dinosaur Trail, Santa Fe, NM 87508, USA * Correspondence: [email protected]; Tel.: +1-505-954-2251 Received: 9 February 2019; Accepted: 8 March 2019; Published: 14 March 2019 Abstract: Tree-ring fire scars, tree ages, historical photographs, and historical surveys indicate that, for centuries, fire played different ecological roles across gradients of elevation, forest, and fire regimes in the Taos Valley Watersheds. Historical fire regimes collapsed across the three watersheds by 1899, leaving all sites without fire for at least 119 years. Historical photographs and quaking aspen (Populus tremuloides Michx.) ages indicate that a high-severity fire historically burned at multiple high-elevation subalpine plots in today’s Village of Taos Ski Valley, with large high-severity patches (>640 ha). Low-severity, frequent (9–29-year median interval) surface fires burned on the south aspects in nearby lower elevation dry conifer forests in all watersheds. Fires were associated with drought during the fire year. Widespread fires commonly burned synchronously in multiple watersheds during more severe drought years, preceded by wet years, including fire in all three watersheds in 1664, 1715, and 1842. In contrast, recent local “large” wildfires have only burned within single watersheds and may not be considered large in a historical context. -

Legacies shape us; they define our identity. The American Indians in Colorado are a fundamental part of our heritage and, more importantly, their influence is crucial to Colorado’s character today. With this in mind, I am both proud and honored to have a key role in bettering the lives of Colorado’s American Indian community. The Colorado Commission of Indian Affairs is pleased to present the fifth edition of the Colorado Directory of American Indian Resources. The Commission is dedicated to serving with the Ute Mountain Ute and Southern Ute Tribes, as well as the Native American community throughout Colorado. Through educational, occupational, economic, and health–based efforts, the commission aspires to improve the overall quality of life for Colorado’s American Indians while preserving the culture and traditions that are so important to our history. Government–to–government communication has been and will continue to be imperative in achieving this objective. The Commission, in association with the Colorado Legislature and the Rocky Mountain Indian Chamber of Commerce, has already procured funding for the American Indian Scholarship Fund. Native American specialty license plates, the first of their kind in Colorado, finance the fund with the proceeds from their sales. -
