Rock and Mineral Treasures: Geological Digital Photography
Featuring photos of otherworldly color and beauty from the Rice Museum collection.
Julian Gray, Executive Director
Rice Northwest Rock and Mineral Museum
Geologists constantly need to depict rocks, minerals, and fossils for presentations and publications. Digital photography has extended the range of possibilities in illustrating samples. One common problem, reduced depth of field at high magnifications, is easily overcome using stacking techniques. This technique uses sharply focused portions of sequential photographs focused on different slices or stacks to produce a synthesized images in which the subject is crisply focused. Julian Gray, executive director of the Rice Northwest Museum of Rocks and Minerals, is a geologist and semi-professional photographer who has experimented with stacking techniques and others to produce stunning images. Julian's specialty is photomicrography. His images have been published in mineral magazines and books.
Past President Larry Purchase and current Vice President Bo Nonn will lead a two-day field trip to the north side of Mt. Hood. From our camp at Cloud Cap Saddle Campground we will climb onto the nearby Cooper Spur moraine to view the terminus of Eliot glacier and discuss the morphology of the Hood’s largest glacier and its periglacial features. Farther downslope we will examine the site of a major debris flow which passed down Eliot Creek in 2006. Nearby is the upper end of the 9km long Parkdale lava flow, a basaltic lava flow less than 8,000 years old. If possible we will examine the more accessible portions of the lava flow including the vent area.
Sunday, August 2nd, 2015 at 12:00 noon at Guy Talbot State Park in the Columbia Gorge (same location as last year). After the picnic, participants may wish to take the short walk to Latourell Falls, or drive to the trailhead near the freeway exit and hike up to Angel's Rest.
Bring your own beverages and we will provide the plates and plastic utensils. The format for the picnic will be a potluck. If your last name begins with:
A through G bring a main dish
H through P bring a side dish or salad
Q through Z bring dessert..
Ancient Walls: A Geological Walking Tour of Downtown Portland
Come see billion-year-old building stones and the fossils hidden under our feet. Join us Saturday, August 22nd 9:00 a.m. for a two-hour outdoor walking tour of downtown Portland’s geological mysteries and oddities. Bring good walking shoes, sunscreen and clothing for a cool, but possibly rapidly warming summer morning. Water and snacks are advisable, although the trip will end at a lunch stop. Open to public. Children under 12 must be supervised.
REGISTRATION FOR THIS TRIP IS CLOSED. President Janet Rasmussen will lead a field trip to the Steens Mountain area of Southeast Oregon. The first and last days are travel days. Participants are encouraged to make lodging plans at or near the Steens Mountain Resort (SMR), just a few miles east of the town of Frenchglen, Oregon. This trip will explore four general areas:
- Diamond Craters and the Peter French Round Barn
- Steens Mountain Loop,
- Lakes and springs east of Steens Mountain
- Older terranes on the eastern side of the Pueblo Mountains.
Most field trips require GSOC membership. Learn more about joining GSOC!
