How to Prepare for Traveling on I-70 in Glenwood Canyon (Spring 2021)
How to prepare for traveling on I-70 in Glenwood Canyon (Spring 2021) I-70 in Glenwood Canyon Motorists traveling on Interstate 70 should prepare for reduced speeds, slick roads and limited visibility in Glenwood Canyon, as well as other spring weather conditions that are common along the I-70 mountain corridor. If there is rain in the forecast, motorists should anticipate a possible safety closure of I-70, rest areas and the Glenwood Canyon bike path in the canyon. These safety closures are to protect the traveling public from the potential for debris flow, mudslides or rockfall. Construction impacts will be much lighter on I-70 in Glenwood Canyon compared to Summer 2020. To ensure safety, motorists should plan for occasional lane closures, obey reduced speeds and drive with caution. CDOT also urges travelers to stay focused on the road and avoid distracted driving. Please see below for information about the Glenwood Canyon rest areas and bike path. How to plan ahead Motorists planning to travel on I-70, visit rest areas or ride the bike path in Glenwood Canyon should pay close attention to weather forecasts. I f there is rain in the forecast, be prepared for a safety closure of I-70, rest areas and bike path. CDOT recommends that travelers have a back up plan in the event that closures are necessary. Please refer to w ww.cotrip.org for the latest road conditions and route options. More information is below for planning an alternate route. CDOT also recommends that travelers bring an emergency kit with water, snacks, a flashlight and a blanket, as mountain conditions often change suddenly. -

Mesozoic Stratigraphy at Durango, Colorado
160 New Mexico Geological Society, 56th Field Conference Guidebook, Geology of the Chama Basin, 2005, p. 160-169. LUCAS AND HECKERT MESOZOIC STRATIGRAPHY AT DURANGO, COLORADO SPENCER G. LUCAS AND ANDREW B. HECKERT New Mexico Museum of Natural History and Science, 1801 Mountain Rd. NW, Albuquerque, NM 87104 ABSTRACT.—A nearly 3-km-thick section of Mesozoic sedimentary rocks is exposed at Durango, Colorado. This section con- sists of Upper Triassic, Middle-Upper Jurassic and Cretaceous strata that well record the geological history of southwestern Colorado during much of the Mesozoic. At Durango, Upper Triassic strata of the Chinle Group are ~ 300 m of red beds deposited in mostly fluvial paleoenvironments. Overlying Middle-Upper Jurassic strata of the San Rafael Group are ~ 300 m thick and consist of eolian sandstone, salina limestone and siltstone/sandstone deposited on an arid coastal plain. The Upper Jurassic Morrison Formation is ~ 187 m thick and consists of sandstone and mudstone deposited in fluvial environments. The only Lower Cretaceous strata at Durango are fluvial sandstone and conglomerate of the Burro Canyon Formation. Most of the overlying Upper Cretaceous section (Dakota, Mancos, Mesaverde, Lewis, Fruitland and Kirtland units) represents deposition in and along the western margin of the Western Interior seaway during Cenomanian-Campanian time. Volcaniclastic strata of the overlying McDermott Formation are the youngest Mesozoic strata at Durango. INTRODUCTION Durango, Colorado, sits in the Animas River Valley on the northern flank of the San Juan Basin and in the southern foothills of the San Juan and La Plata Mountains. Beginning at the northern end of the city, and extending to the southern end of town (from north of Animas City Mountain to just south of Smelter Moun- tain), the Animas River cuts in an essentially downdip direction through a homoclinal Mesozoic section of sedimentary rocks about 3 km thick (Figs. -

The Green Team established a grass-roots partner- ship called the Four Corners Recycling Initiative, which works on leveraging in-kind and matching donations. Their efforts have brought recycling opportunities for cardboard, mixed paper and mixed metals to fed- eral and local government institutions, schools, and pri- vate businesses in Montezuma County.

Summary of Animas River Stakeholders Group History of Watershed Activities 1994 to Present February 2008
1185690-R8 SDMS Summary of Animas River Stakeholders Group History of Watershed Activities 1994 to Present February 2008 Excerpted from ARSG webpage: The Animas River Stakeholders Group (ARSG) was formed in 1994 in response to the Colorado Water Control Division's (WQCD) re evaluation and upgrading of water quality standards for the Upper Animas River Basin. This basin, with the headwaters ofthe river located near the old mining community of Silverton, Colorado, had long been contaminated by both historic mining practices and natural mineralization. With the implementation ofthe new standards, and additional standards put in place in 1995, local participants including mining companies, elected officials, local citizens, land owners, envirormiental groups, and federal agencies came together to address the issues raised by the state. At first, with the diverse interests ofthe groups involved, the process was slow, however they continued to meet, find common ground, and work together for improved water quality in the Animas River Basin. Because the Animas River is a very complex and dynamic ecosystem, it would take several years of research and field work to collect the data needed to improve water quality and habitat degradation that has occurred for so many years. In support ofthe grassroots efforts put forth by the Stakeholders, the WQCC granted an extension ofthe ambient (existing) water quality standards allowing for additional time to complete field studies, consider remediation techniques, and make meaningful recommendations to the Commission, which they did in 2001. After studying 1,500 mine sites in the region, ARSG identified 67 priority waste sites that they judged to be the highest ranking contributors of metals in the Animas River. -

Delayed and Rapid Deglaciation of Alpine Valleys in the Sawatch Range, Southern
Delayed and rapid deglaciation of alpine valleys in the Sawatch Range, southern Rocky Mountains, USA Joseph P. Tulenko1, William Caffee1, Avriel D. Schweinsberg1, Jason P. Briner1, Eric M. 5 Leonard2. 1. Department of Geology, University at Buffalo, Buffalo, NY 14260, USA 2. Department of Geology, Colorado College, Colorado Springs, CO 80903, USA 10 Abstract We quantify retreat rates for three alpine glaciers in the Sawatch Range of the southern Rocky Mountains following the Last Glacial Maximum using 10Be ages from ice-sculpted, valley-floor bedrock transects and statistical analysis via the BACON program in R. Glacier retreat in the Sawatch Range from at (100%) or near (~83%) Last 15 Glacial Maximum extents initiated between 16.0 and 15.6 ka and was complete by 14.2 – 13.7 ka at rates ranging between 35.6 to 6.8 m a-1. Deglaciation in the Sawatch Range commenced ~2 – 3 kyr later than the onset of rising global CO2, and prior to rising temperatures observed in the North Atlantic region at the Heinrich Stadial 1/Bølling transition. However, deglaciation in the Sawatch Range approximately aligns 20 with the timing of Great Basin pluvial lake lowering. Recent data-modeling comparison efforts highlight the influence of the large North American ice sheets on climate in the western United States, and we hypothesize that recession of the North American ice sheets may have influenced the timing and rate of deglaciation in the Sawatch Range. 1 While we cannot definitively argue for exclusively North Atlantic forcing or North 25 American ice sheet forcing, our data demonstrate the importance of regional forcing mechanisms on past climate records. -
