RECENT EOU GEOLOGY TRIPS!
Phi Beta Rock at Bryce Canyon (2007)
GEOLOGY Weekend College Trips, Spring 2014
It was a busy spring for our Weekend College classes. Mark Ferns led his GEOL 105 Earthquakes and Volcanoes class on an exciting (and cold!) field trip to the Leslie Gulch area. Only 3 flat tires!
Jay Van Tassell guided his GEOL 310 Geology of the Grande Ronde Valley class in April on a trip around the Grande Ronde Valley and up to Anthony Lakes, where the weather was fabulous. One student from the Bahamas got to see snow for the first time on a beautiful blue-sky day!
In May, Jay led his GEOL 310 John Day Fossils class to the Dayville and Mitchell areas, including a new Cretaceous site where the students found some beautiful cephalopods, echinoids, and bivalves, and gastropods. We also found a sample that may contain vermetid gastropods, also known as “worm gastropods”!
GEOL 451 Hydrology Trips, Spring 2014
This year’s Hydrology class was happy to discover that that there water in the Powder River in the Keating Valley in contrast to the trip last year when the river was dry. The students picked up the techniques of stream gaging quickly and had a great time using the flow meter and pipe dredge!
GEOL 311 Mineralogy Trip, Winter 2014
The winter weather was not too bad as we headed down to the Oregon Trail Museum to look at their mining display and then off to visit the basanite vent nearby in the Keating Valley. The Baker Heritage Museum’s display of minerals was a big hit, especially the black light display, but the best part was yet to come– collecting feldspars in Lime and zeolites near Farewell Bend. What a great way to spend a winter day!
GEOL 201 Physical Geology Trip, Fall 2013
The tamaracks at Boulder Park were in full color when we arrived this year– two beautiful fall days in the mountains! This year we pondered whether what the rock unit that has been called Hurwal in this area is actually part of the Martin Bridge Formation, but we haven’t solved the dilemma yet. Maybe next year! A great time was had by all!

GEOL 334 Sedimentology Trip, Fall 2013
It is supposed to be cold and rainy with a storm or a tsunami on the horizon when we head to the beach for our Sedimentology trip. Not this year! Shirt sleeves and blue skies– where are we, really? A great time was had by all!The group (Jesta Knoles, Sky Hickey, Kara Harris, Cole Griffin, Garrett Zinzer, Don Scott, Chane’ Nelson, and Josh Roth at Arcadia Beach (top left), Fort Stevens (top right), Nehalem Beach (bottom left), and Hug Point (bottom right).
GEOL 203 Historical Geology Trip, Spring 2013
It was a great weekend to go to John Day. The group was small, but enthusiastic. We postponed hunting for cephalopods due to a bit of rain. Better luck next year!The group poses at the Cant Ranch.

GEOL 451 Hydrology Trip, Spring 2013
It’s supposed to rain for a hydrology trip, but this didn’t happen this year! It was beautiful on Saturday’s trip to the upper Grande Ronde River and Sunday’s trip to examine the North Powder River had beautiful blue skies as well. There was only one problem– when we got to our first stop on the Powder River on Sunday, the river wasn’t flowing! We found out later that the flow had been shut off at Thief Valley Reservoir. Oh well, we had a good time anyway!The class measures the flow of the Grande Ronde River at Hilgard. Jalina Johnston shows the correct way to hold the surveying rod.
