Mt. Olympus, mythological home of the Greek gods, Yosemite’s Half Dome, the ever-classic Matterhorn, Alaska’s Denali, and Colorado’s Pikes Peak all share the quality of compelling attraction that a charismatic alpine profile evokes. At the base of our peak along the confluence of two small, nondescript streams, Native Americans gathered thousands of years ago. Explorers, immigrants, city-visionaries and fortune-seekers arrived successively, all shaping in turn the region and communities that today spread from the flanks of Pikes Peak. From any vantage point along the Interstate 25 corridor, the Colorado plains, or the Arkansas River Valley escarpments, Pikes Peak looms as the dominant feature of a diverse “bioregion”, a geographical area with a distinct flora and fauna, that stretches from alpine tundra to desert grasslands. “Biodiversity” is shorthand for biological diversity: a term covering a broad array of contexts from the genetics of individual organisms to ecosystem interactions. The news tells us daily of ongoing threats from the loss of biodiversity on global and regional levels as humans extend their influence across the face of the earth and into its sustaining processes. On a regional level, biologists look for measures of biodiversity, celebrate when they find sites where those measures are high and mourn when they diminish; conservation organizations and in some cases, legal statutes, try to protect biodiversity, and communities often struggle to balance human needs for social infrastructure with desirable elements of the natural landscape. -
Denudation History and Internal Structure of the Front Range and Wet Mountains, Colorado, Based on Apatite-Fission-Track Thermoc
NEW MEXICO BUREAU OF GEOLOGY & MINERAL RESOURCES, BULLETIN 160, 2004 41 Denudation history and internal structure of the Front Range and Wet Mountains, Colorado, based on apatitefissiontrack thermochronology 1 2 1Department of Earth and Environmental Science, New Mexico Institute of Mining and Technology, Socorro, NM 87801Shari A. Kelley and Charles E. Chapin 2New Mexico Bureau of Geology and Mineral Resources, New Mexico Institute of Mining and Technology, Socorro, NM 87801 Abstract An apatite fissiontrack (AFT) partial annealing zone (PAZ) that developed during Late Cretaceous time provides a structural datum for addressing questions concerning the timing and magnitude of denudation, as well as the structural style of Laramide deformation, in the Front Range and Wet Mountains of Colorado. AFT cooling ages are also used to estimate the magnitude and sense of dis placement across faults and to differentiate between exhumation and faultgenerated topography. AFT ages at low elevationX along the eastern margin of the southern Front Range between Golden and Colorado Springs are from 100 to 270 Ma, and the mean track lengths are short (10–12.5 µm). Old AFT ages (> 100 Ma) are also found along the western margin of the Front Range along the Elkhorn thrust fault. In contrast AFT ages of 45–75 Ma and relatively long mean track lengths (12.5–14 µm) are common in the interior of the range. The AFT ages generally decrease across northwesttrending faults toward the center of the range. The base of a fossil PAZ, which separates AFT cooling ages of 45– 70 Ma at low elevations from AFT ages > 100 Ma at higher elevations, is exposed on the south side of Pikes Peak, on Mt. -
Railcars at Rocky Flats Community Final 11-04-04.Indd
Rocky Flats Fact Sheet Transporting low-level radioactive waste from Rocky Flats using railcars Transporting low-level radioactive waste from Rocky Flats using railcars The Rocky Flats Closure Project is one of the largest environmental cleanup operations in the world. Rocky Flats, located approximately 15 miles northwest of Denver, produced plutonium and uranium components for the U.S. nuclear weapons program from 1953 until 1989. The operations left a legacy of radioactive and hazardous waste contamination. Cleanup operations began in earnest in 1995. As part of closure, all radioactive and hazardous waste will be shipped from Rocky Flats to waste disposal sites in other states. No waste will be permanently stored or disposed of on site. Currently, all low-level radioactive waste leaving Rocky Flats is transported by truck. As the Rocky Flats Closure Project Cleaning up Rocky Flats will return thousands of acres to the citizens of Colorado. The nears completion, demolition of former site will become a national wildlife refuge. manufacturing buildings signifi cantly increases the volume of low-level radioactive waste. To improve effi ciency and worker safety, the project will use railcars to ship very low-level waste to the Envirocare disposal facility in Utah. Using rail may eliminate as many as 5,000 truck shipments. Background The complex job of cleaning up and closing down Rocky Flats involves removing massive quantities of radioactive waste. To date, after nine years of shipping, Rocky Flats has safely shipped approximately 260,000 cubic meters (65 percent) of the projected 400,000 cubic meters of radioactive waste that will be generated during closure. -

S Oldest Railway Roundhouse at Curzon Street Archaeological Site
HS2 uncovers world’s oldest railway roundhouse at Curzon Street archaeological site March 11, 2020 HS2 Ltd has unearthed what is thought to be the world’s oldest railway roundhouse at the construction site of its Birmingham Curzon Street station. The roundhouse was situated adjacent to the old Curzon Street station, which was the first railway terminus serving the centre of Birmingham and built during a period of great significance and growth for the city. Built to a design by the 19th century engineer Robert Stephenson, the roundhouse was operational on 12 November 1837 – meaning the recently discovered building is likely to predate the current titleholder of ‘world’s oldest’ in Derby by almost two years. HS2’s initial programme of trial trenching at Curzon Street revealed the remains of the station’s roundhouse, exposed toward the south-eastern corner of the site. The surviving remains include evidence of the base of the central turntable, the exterior wall and the 3ft deep radial inspection pits which surrounded the turntable. The 19th century station at Curzon Street is among the very earliest examples of mainline railway termini and the limited later development of the site means that any surviving remains of the early station represents a unique opportunity to investigate a major early railway terminus in its entirety. As the HS2 project heads towards Main Works Civils, the final archaeological excavations on the site are about to take place. HS2 will see the site become home to the first brand new intercity terminus station built in Britain since the since the 19th century. -

Russia 2Faculty of Operation and Economics of Transport and Communications, Zilina, Univerzitná 8215/1, 010 26, Republic of Slovakia Abstract. The article studies the main trends in the market of container transportation in rolling stock of various types, considers the process of transporting large-capacity containers in open wagons. The operational and economic aspects of removing administrative restrictions on the implementation of this type of transportation are noted. The dynamics of rental rates for rental of gondola cars and platforms in 2019-2020 is present. The summary characteristics of the gondola car fleet and fitting platforms on the Russian Railways network have been study. The analysis of the market share of the largest owners of gondola cars and fitting platforms was carry out. The advantages and disadvantages of using the technology of container transportation in open wagons are list. Solutions are propose to create a competitive environment in the container transportation segment of the transport services market. 1 Introduction Currently, containers are transport on fitting platforms, but theoretically, according to international rules, they can also be transport in open wagons: 40-feet - horizontally per piece, 20-feet - two each, and empty 20-feet - even three. From December 1, 2014, the local technical conditions (LTC) for the placement and fastening of universal containers in gondola cars with unloading hatches were cancel. -

The journal was patterned after the journal Radiocarbon and covered isotopic age-dating (except carbon-14) on rocks and minerals from the Western Hemisphere. Initially, the geographic scope of papers was restricted to the western half of the United States, but was later expanded. The journal was sponsored and staffed by the New Mexico Bureau of Mines (now Geology) & Mineral Resources and the Nevada Bureau of Mines & Geology.
