Future Colorado Scientific Society Meetings and Field Trips

Geology of the Upper Arkansas Valley
CSS 2018 Fall Field Trip

September 15-16, 2018

Led by Karl Kellogg, Cal Ruleman, Scott Minor, Jonathan Caine, and other USGS geologists

Upper Arkansas Valley Field Trip Announcement

View to the northeast showing Leadville, Colo., from the flank of Mount Elbert and geographic features relative to the Leadville North, Colo. 7.5′ quadrangle.

Spend Two Days examining diverse Geologic features of the beautiful Upper Arkansas Valley:

  • Proterozoic sedimentation, volcanism, and plutonism
  • Laramide Orogeny structural features
  • Northern Rio Grande Rift and Upper Arkansas Valley magmatism, tectonism, and sedimentation
  • Pre-rift intrusive rocks and Oligocene and Eocene volcanic rocks
  • Glacial history and deposits including catastrophic outwash floods
  • Mineral deposits (gold, silver, copper, zinc, lead, fluorspar, and others)
  • Landslide, alluvial, mass-movement, eolian, and wetland deposits

There is something for everyone!

Logistic details are still to be worked out, but the group will spend one night at a motel, either in Salida or Buena Vista, and travel will be either be rented vans or personal car-pooling.

If you are interested in going on the trip, please contact Cal Ruleman, cruleman@usgs.gov, and let him know of your interest so he can compile a tentative list of who wants to go on the trip. We’ll share more information once it is available.

Abstracts of Past Colo. Scientific Society Meetings


The Colorado Scientific Society was founded in 1882 as a forum for the exchange of observations and ideas on the topics of earth science. Our lecture series occurs on the third Thursday of each month, from September through May. Lecture topics largely focus on earth science, and are open to the public. In addition to our monthly lecture series, the society is also active in public service. We fund student research grants, construct and post signs that describe local geologic features, and organize and lead several field trips.


The Colorado Scientific Society usually meets on the third Thursday of the month from September through May at The Shepherd of the Hills Presbyterian Church, 11500 W. 20th Ave., Lakewood CO
Social time is at 6:30; meeting & program at 7:00
(In the summer months of June-August, too many are off in the field.)
