  • 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.

  • A Train Trip in Five Hundred Words Dennis Payton Knight We Are
    A Train Trip in Five Hundred Words Dennis Payton Knight We are about to embark, in five hundred words, on a virtual journey through the Northwestern United States. We are making this excursion in June to capitalize on the extra available daylight hours, and I will cast aside excess adjectives and adverbs for maximum word mileage. All aboard. The time is eight a.m., and we are seated on Amtrak’s California Zephyr leaving Denver, proceeding west through town, to begin our ascent of the Rockies through South Boulder Canyon. In the first fifty miles we will navigate thirty-one tunnels, the last being the six-mile Moffat Tunnel under the Continental Divide. We will exit the Moffat at ten into Winter Park. It was nice of Amtrak to schedule this Colorado part of the Zephyr’s journey in the morning because there is much ahead to see. Years ago, you would hear a rhythmic clickity-clack as the wheels traversed welded joints along the rails. Now tracks are seamless and quiet, but it has taken away part of the romance of trains. We will glide through beautiful (essential adjective) Glenwood Canyon, through wild horse territory, the peach orchards of Palisade and into Grand Junction, where the Gunnison joins the Colorado River. In Ruby Canyon at five p.m. we will enter Utah and shortly get our last sight of the Colorado River. This is when we will begin to realize how breathtakingly (essential adverb) the monumental red, nature-carved landscapes (essential adjectives) of Utah contrast with colorful Colorado’s own spectacular scenery (more essential adjectives.) We will cruise several hundred more miles, reaching Salt Lake City at night.

  • Constraining the Timing of River Incision in the Upper Colorado Drainage Basin Using Apatite (U-Th)/He Thermochronology in the Elk Mountains, Western Colorado
    Constraining the Timing of River Incision in the Upper Colorado Drainage Basin Using Apatite (U-Th)/He Thermochronology in the Elk Mountains, Western Colorado Coleman Hiett Department of Geological Sciences University of Colorado, Boulder Departmental Honors Thesis April 10, 2017 Thesis Advisor: Lon Abbott, Department of Geological Sciences Defense Committee Members: Charles Stern, Department of Geological Sciences Lisa Barlow, Baker Residential Academic Program ABSTRACT This study utilizes apatite (U-Th)/He, or AHe, to produce a vertical transect of cooling histories along the height of the partially exhumed Crystal Pluton in the Elk Mountains of west/central Colorado. These cooling histories are interpreted to reflect exhumation controlled by the incision of the Crystal River – a tributary of the Colorado River. A period of rapid exhumation is observed from 8 – 11 Ma, likely beginning earlier, that is consistent with previous AHe data taken from nearby exhumed plutons in the Elk and northern West Elk Mountains. This period of exhumation predates the incision of a low relief surface that developed in northwestern Colorado by ca. 10 Ma, and is therefore not believed to have been controlled by the incision of the Colorado River. A review of previously noted incision constraints suggests that post-10 Ma Colorado River incision has become more rapid in the last 1 – 3 Ma, suggesting that climate change, rather than epeirogenic uplift, is the major driver for recent river incision. 1. INTRODUCTION 1.1 Concerns of the Colorado River For more than a century, geologists have struggled to better understand the geologic evolution of the western United States.
