First announcement and call for papers

July 29 to August 1, 2010

TRGS's 2010 Field Conference will be held between Thursday evening, July 29, and Sunday, August 1, in Anaconda, Montana. Talks are planned for Friday morning with field trips on Friday, Saturday, and Sunday. We will be using the High School for our principal venue and will have breakfast and lunches and Friday dinner available from a student group. The TRGS barbeque will, as usual, be Saturday evening's featured event, and we have a city park reserved for Friday dinner as well.

The immediate vicinity of Anaconda has complex geology that has been the focus of field work for a century and several trips are in the works to explore some diverse aspects of that geology. Some examples: Jeff Lonn will show structures of the Eocene Anaconda Metamorphic Core Complex in Lost Creek Canyon, leading a hike (for hardy souls) to the north rim of Lost Creek Canyon to examine ductile and brittle structures along the Anaconda detachment fault. Skip Yates will lead a trip that will look at structure, stratigraphy and mineralization in upper Warm Springs Creek and the vicinity of the Hidden Lake and Cable mines. Bruce Cox and Paul Antonioli are putting together a trip that will look at active mines and general geology in the Highland range south of Butte. Jim Sears of the University of Montana and his students will lead a field trip highlighting their work to test the hypothesis that the Big Hole Valley contained a Middle Miocene lake that discharged a big river that carved the Big Hole Canyon and dumped the eroded sediment into an enormous fan delta in a second Middle Miocene lake at Twin Bridges.

We will have more details on all these trips (and several more!) when we send out the conference registration information in late Spring. Updated information will be posted periodically here or the TRGS facebook page. We are also posting links to papers, cross-sections, maps, and other information related to both the field conference and news of interest to Society members on the facebook page.

If you would like to contribute a paper to our guidebook, please contact Bruce Cox, technical editor of this year's guidebook. There is a hard deadline of June 1 for submissions. Authors for the guidebook should refer to the Editorial Requirements (PDF). Please especially note formats - do not send texts in DOCX format, and please do not embed images in word documents - send as separate JPGs. If you would like to participate by leading a field trip, or have other questions regarding the conference, kindly contact one of the organizers, Ted Antonioli or Katie McDonald.

Camping in the area is abundant, particularly at several USFS campgrounds in upper Warm Springs Creek only 10-15 minutes from town, and at Lost Creek State Park.
