All trips begin and end at the Colorado Convention Center in Denver, unless otherwise indicated. Details about the precise trip itinerary are provided upon registration or you may contact the field trip leaders directly. Participants are cautioned against scheduling any tight travel connections with field trip return times, as those times are estimates, and delays in the field may occur. For a list of hotels near the airport, contact GSA.
If you register just for a field trip, you must pay a non-registrant fee in addition to the field trip fee. This fee may be applied toward meeting registration if you decide to attend the meeting. Trip fees include transportation during the trip and a trip guide.
DURING THE MEETING
- 417. Revisiting the South Cañon Number 1 Coal Mine Fire during a Geologic Excursion from Denver to Glenwood Springs, Colorado
Cosponsored by GSA Coal Geology Division
Sun., 28 Oct.
- Glenn B. Stracher, East Georgia College, +1-478-289-2073, ; Nancy Lindsley-Griffin; Steven Renner; Janet L. Stracher; Jim Viellenave.
- While en route from Denver to Glenwood Springs, Colorado we will discuss important geologic features observable from milepost markers along the way. Traveling west of Glenwood Springs to South Canyon, we will visit the locale where an underground coal-mine fire has been burning since 1910. While in the canyon, gas vents, ground fissures and subsidence, and forest fires associated with the South Cañon Number 1 Coal Mine fire will be examined and their origin and environmental significance discussed. Field-trip attendees are encouraged to participate in the following demonstrations: VaporTec passive soil gas sampling, mineral sampling at hot-gas vents, in situ gas analysis using Drager tubes, and gas collection techniques for complete coal-fire gas analysis. The trip involves hiking, includes snacks and lunch, and culminates in a relaxing dip in Glenwood Spring's "Hot Springs Pool," before returning to Denver. Field-trip guides include specialists in structural and economic geology, mineralogy and petrology, geochemistry, coal geology, and remote sensing.
- Min: 12; max: 45. Cost US$75 (L, R)
- 418. Old and New Geologic Studies along the Front Range between Golden and Morrison, Including Structural, Volcanic, and Economic Geology and Paleontology (1)
Cosponsored by Friends of Dinosaur Ridge; GSA Geoscience Education Division; GSA Sedimentary Geology Division
Sun., 28 Oct. — FULL
- Tim Connors, National Park Service, +1-303-969-2093, ; T. Caneer; Norbert Cygan; Harald Drewes.
- This field trip will visit the Laramide uplifted late Paleozoic to early Cenozoic stratigraphic interval exposed between Golden and Morrison, Colorado. Topics to be presented include dinosaur remains of three ages, folds, faults, and two-stage volcanism associated with the Laramide Orogeny. Economic deposits, past and present, will be observed along the way, including a uranium roll front and oil seeps near Morrison. This field trip provides geologic educators with an opportunity to view excellent field lab sites for geology instruction, including Mesozoic dinosaur tracks and bones of the Dakota Sandstone and Morrison Formation. Field trip stops will include the classic dinosaur track site at Dinosaur Ridge, Triceratops Trail, Red Rocks Park, and North and South Table Mountains.
- Min: 12; max: 45. Cost US$85 (L)
- 419. Kirk Bryan Field Trip: Fluvial-Hydraulic Processes in the Colorado Front Range
Cosponsored by GSA Quaternary Geology and Geomorphology Division
Tues., 30 Oct. — FULL
- John Pitlick, University of Colorado, +1-303-492-5906, ; Ellen Wohl.
- On this one-day field trip, attendees will discuss the flood hydrology and geomorphology of Front Range river systems. The main destination for the field trip is the canyon of the Poudre River, west of Fort Collins, Colorado. The trip will involve a 1-hour drive from Denver to Ft. Collins, then up the Poudre River canyon a short distance to the field site. Most of the day will be spent at one or two sites; the group will return to Denver by 6 p.m. Topics to be covered during the field trip will include (1) frequency of major flooding on Front Range rivers; (2) the role of episodic erosion in landscape evolution; (3) fluvial response to fire; and (4) sediment transport and morphodynamics of high-gradient river systems.
- Min: 20; max: 50. Cost US$70 (L, R)
- 420. Denver's Building Stones
Tues., 30 Oct.
Jack Murphy, Denver Museum of Nature & Science, ; Robert G. Raynolds.
- On this trip, you'll visit a series of buildings in downtown Denver and examine the rock types that were used to construct and decorate the edifices. We will see a wide variety of urban geology, from richly decorative rocks imported from around the world to local material quarried within sight of Denver.
- Min: 15; max: 30. Cost US$39 (R)
