Stratigraphy and Correlation of Glacial Deposits of the Rocky Mountains, the Colorado Plateau and the Ranges of the Great Basin
STRATIGRAPHY AND CORRELATION OF GLACIAL DEPOSITS OF THE ROCKY MOUNTAINS, THE COLORADO PLATEAU AND THE RANGES OF THE GREAT BASIN Gerald M. Richmond u.s. Geological Survey, Box 25046, Federal Center, MS 913, Denver, Colorado 80225, U.S.A. INTRODUCTION glaciations (Charts lA, 1B) see Fullerton and Rich- mond, Comparison of the marine oxygen isotope The Rocky Mountains, Colorado Plateau, and Basin record, the eustatic sea level record, and the chronology and Range Provinces (Fig. 1) together occupy much of of glaciation in the United States of America (this the western interior United States. These regions volume). include approximately 140 mountain ranges that were glaciated during the Pleistocene. Most of the glaciers Historical Perspective were valley glaciers, but ice caps formed on uplands Following early recognition of deposits of two alpine locally. Discussion of the deposits of all of these ranges glaciations (Gilbert, 1890; Ball, 1908; Capps, 1909; would require monographic analysis. To avoid this, Atwood, 1909), deposits of three glaciations gradually representative ranges in each province are reviewed. became widely recognized (Alden, 1912, 1932, 1953; Atwood and Mather, 1912, 1932; Alden and Stebinger, Purpose and Scope 1913; Blackwelder, 1915; Atwood, 1915; Fryxell, 1930; This report summarizes the evidence for correlation Bradley, 1936). Subsequently drift of the intermediate of the Quaternary glacial deposits in 26 broadly glaciation was shown to represent two glacial advances distributed mountain ranges selected on the basis of (Fryxell, 1930; Horberg, 1938; Richmond, 1948, 1962a; availability of detailed information and length of glacial Moss, 1951a; Nelson, 1954; Holmes and Moss, 1955), record. and the older drift was shown to include deposits of Because the glacial deposits rarely are traceable from three glaciations (Richmond, 1957, 1962a, 1964a). -

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. -

Historical Background Study, Curecanti Recreation Area, Colorado
•••••a••• ••••a••••aa•a COLORADO Historical Background Study By BENJAMIN LEVY DIVISION OF HISTORY Office of Areheology and Historic Preservation October 15, 1968 National Park Service B&WScans U.S. Department of the Interior ..S·fb·~~ FOREIDRD The object of th.is study is to provide the historical data necessary :fOJ: the proper development of a Master Plan for Curecanti Rec:ceation Area, Colorado. This study, authorized by Resource Study Proposal (RSP) CURE-H-1, seeks to identi:fy historical resources and historic sites lo cated within or closely associated with the recreation area. Such an undertaking will enable master planning teams to consider the use o:f historical data in interpre tive and development programs and provide £or the protection 0£ historic sites and structures. Ideally, thE! background study ought to precede the master plan team's field investigation. The urgency 0£ the Curecanti plan r1equired this investigation to be undertaken immediately at the beginning of the current :fiscal year and compelled it to be done while the team was in the field. Hopefully, this report will have found its way into the team's hands prior to their completion report. This report does not pretend to be a detailed or de £ini tive study of the history 0£ the Curecanti area. The urgency of the c:all of this document and the limited time assigned for its preparation permit little more than the examination of secondary sources, although little i published mateI'ial exists on the history ox that stretch of the Gunnison River from Montrose to Gunnison city. -

Bauer, 1971, pp. 231-234 in: San Luis Basin (Colorado), James, H. L.; [ed.], New Mexico Geological Society 22nd Annual Fall Field Conference Guidebook, 340 p. This is one of many related papers that were included in the 1971 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

IUCN Red List of Threatened Species™ to Identify the Level of Threat to Plants
Ex-Situ Conservation at Scott Arboretum Public gardens and arboreta are more than just pretty places. They serve as an insurance policy for the future through their well managed ex situ collections. Ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. In situ means "on site", so in situ conservation is the conservation of species diversity within normal and natural habitats and ecosystems. The Scott Arboretum is a member of Botanical Gardens Conservation International (BGCI), which works with botanic gardens around the world and other conservation partners to secure plant diversity for the benefit of people and the planet. The aim of BGCI is to ensure that threatened species are secure in botanic garden collections as an insurance policy against loss in the wild. Their work encompasses supporting botanic garden development where this is needed and addressing capacity building needs. They support ex situ conservation for priority species, with a focus on linking ex situ conservation with species conservation in natural habitats and they work with botanic gardens on the development and implementation of habitat restoration and education projects. BGCI uses the IUCN Red List of Threatened Species™ to identify the level of threat to plants. In-depth analyses of the data contained in the IUCN, the International Union for Conservation of Nature, Red List are published periodically (usually at least once every four years). The results from the analysis of the data contained in the 2008 update of the IUCN Red List are published in The 2008 Review of the IUCN Red List of Threatened Species; see www.iucn.org/redlist for further details. -

Natural Heritage Assessment of the Uncompahgre River Basin
The Uncompahgre River Basin A Natural Heritage Assessment Volume I Prepared for Valley Land Conservancy Montrose, Colorado March, 1999 By Peggy Lyon, Tom Stephens, Jeremy Siemers, Denise Culver, Phyllis Pineda, and Jennifer Zoerner Colorado Natural Heritage Program 254 General Services Building, CSU Ft. Collins, CO 80523 User’s Guide The Uncompahgre Basin Biological Assessment conducted by the Colorado Natural Heritage Program consists of two essentially distinct projects that are highly integrated with respect to methodology and fieldwork. This report reflects the separate nature of the projects by being organized in a two-volume set. Volume I presents all potential conservation sites that have been identified in the Uncompahgre Basin that support rare and imperiled plants, animals, and significant plant communities, including wetland and riparian areas. Volume II focuses exclusively on wetland and riparian areas. Volume II also presents “locally significant areas.” These are sites that are among the most important wetlands in the Uncompahgre Basin, but they are not unique from a national or statewide perspective, and therefore these sites did not receive a Biodiversity Rank. Additionally, Volume II presents an assessment of the wetland functions performed by each site that was surveyed. These functional assessments are intended to provide the user with a more complete picture of the value wetlands and riparian areas provide to Uncompahgre Basin residents. Both projects utilized the same Natural Heritage Methodology that is used throughout North America, and both searched for and assessed the plants, animals, and plant communities on the Colorado Natural Heritage Program’s List of rare and imperiled elements of biodiversity. -
