GEO 2500, FALL 2005 |
| |
Carol Dehler led a trip on a loop through the Uinta Mountains, starting along the Mirror Lake highway, to the Sheep Creek Geological Area, and Flaming Gorge Reservoir. Then we made a quick stop at Fossil Butte National Monument on the way home! |

GEO 2500, SPRING 2005 |
| |
Joel Pederson led a trip to the Arizona Strip country of the St. George-western Grand Canyon region. The trip followed the Hurricane Cliffs (fault scarps!) down to Tuweep at the awesome rim of western Grand Canyon (Supai Group--see photos below). Even though it was April, it snowed! and we had to bail out of hiking down the side of the Vulcans Throne cinder cone to the river. |

GEO 6800, Graduate Active Margins Seminar, SPRING 2005 |
| |
John Shervais and Brad Ritts led a troupe of graduate students on the Active Margins Seminar, “Sierras to the Sea”, across north-central California. The photo below is of the crew on a Jurassic 'knocker', an eclogite block eroding out of a sea of serpentine on the Tiburon peninsula. |

GEO 2500, SPRING 2004 |
| |
The spring 2004 trip, consisting
of 15 students and Brad Ritts, compared Mesozoic stratigraphy,
depositional environments and fossils between Capitol Reef National
Park and the San Rafael Swell. Along the way, we enjoyed the
spectacular scenery, geomorphology, structure and history of
these world-class soft rock playgrounds.

GEO 6800, Graduate Seminar, Spring Break 2004 |
| |
Dave Liddell led a trip
to Puerto Penasco, Sonora, Mexico with stops along the way at
Marble Canyon and Organ Pipe Cactus National Park, Arizona. We
stayed at the SEDO science institute and explored the tidal flats
(incredible sed structures!), beaches, snorkeling to see strange
sealife, went into the desert to visit the Pinacate volcanic
field, and ate plenty of fish tacos.

GEO 2500, Fall
2003 |
| |
Susanne Janecke, Grasshopper Basin Montana--In the fall
of 2003 Susanne Janecke led a group of students to SW Montana to look
at paleovalleys, thrust faults of the cordillera belt, and supradetachment
basins of Eocene to Oligocene age. We saw large extensional folds in
the Grasshopper basin, megabreccia blocks, an exposure of the basin-bounding
detachment fault with >1 m of clay gouge, and learned about the evolution
of supradetachment basins over time.

GEO 2500, Fall 2002 |
| |
Pete Kolesar took us to Pavant Butte in the Black
Rock Desert - site of the most recent volcanic activity in Utah;
Topaz Mountain, where topaz, the official state gem of Utah, can
be collected; Wheeler Amphitheater, site of world-class trilobites;
Notch Peak; and Crystal Peak, a volcanic tuff at the northern end
of the Wah Wah Mountains.

GEO 2500, Fall 2001 |
| |
John Shervais led us to the Snake
River Plain in southern Idaho, looking at differences in stratigraphy
and volcanology between the eastern and western plains. We started
at the INEEL site near Arco and looked at the Howe Point rhyolite,
then on to Craters of the Moon to look at recent basaltic volcanoes.
On the second day we went to Twin Falls area and looked at volcanic
stratigraphy in the Snake River gorge there, complete with pillow
lavas and basaltic glass deposits. Spent second night at Bruneau
Dunes state park before viewing volcanic and sedimentary rocks
of the western SRP around Mountain Home Idaho. Here we saw lake
sediments of Pliocene Lake Idaho, pillow lava deltas from basalt
that flowed into the lake, rhyolite vitrophyre, a basalt flow with
plagioclase flotation cumulates, and the huge Crater Rings eruptive
center. |

GEO 2500, Spring 2001 |
| |
The Spring field trip was huge. Joel Pederson
took us to the Moab area to look at dinosaur tracks, the formation
of arches and other geomorphic weirdness, Permian through Jurassic
paleogeography, and the overall erosional history of the Colorado
Plateau. Lots of hiking and rustic lodging (camping)--lots
of fun. See photos below: |
