Future Colorado Scientific Society Meetings and Field Trips


CSS Meeting, Tuesday, May 14, 2019
Colorado Scientific Society Emmons Lecture
Synthesis, serendipity, and an open mind: timely approaches to timeless challenges in mineral deposits

Dr. Mark Barton, Univ. of Arizona, Lowell Institute for Mineral Resources. This lecture will take place in conjunction with a two and a half day USGS-CSM-CGS Joint Mineral Resources Forum. The exact location (on the CSM campus) of Mark’s presentation is still TBA. More info will be forthcoming.


CSS Spring Field Trip, Sunday, May 19, 2019
Denver Basin Geology and It’s Rich Cultural, Mining, and Industrial History

LEADERS: Mark Mitchell (Paleocultural Research Group), Jason McGraw (General Shale Brick), Donna Anderson (Colorado School of Mines), and David Lindsey (U.S. Geological Survey, Emeritus)

Join us for a one-day field trip with stops relating cultural, mining, and industrial history to the geologic and Pleistocene geomorphic evolution of the western portion of the Denver Basin.

The trip will include visits to:

  • Magic Mountain Paleo Indian archeological site, Denver Museum of Nature and Science and the Paleocultural Research Group
    This has been in the news because of recent excavations by the Denver Museum of Nature and Science.
    Mark Mitchell will share his findings of the site’s geology, stratigraphy, and Carbon-14 dates and habitation history.
  • Chieftain mine (General Shale Brick, formerly Robinson Brick Company) clay pit on West Alameda Parkway; Jason McGraw of General Shale will lead a tour focused on industrial minerals geology. (He does several types of tours for different audiences.) Hard hats are not required but closed-toe shoes are.
  • The White Ash and Loveland Mines, Golden; discussion led by Donna Anderson, Affiliate faculty, Colorado School of Mines
    This will be the lunch stop. Please bring your own lunch and water.
  • Clear Creek geology and Quaternary geology of the South Platte Basin; at West Lake parking area on Clear Creek on the east side of Youngfield St., south of 42nd Ave. Dave Lindsey will show and discuss Clear Creek Pliocene-Pleistocene stratigraphy and geomorphic relationships related to the Quaternary geology of South Platte basin and incision history of Clear Creek.

We will meet at the I-70 Morrison exit in the Wooly Mammoth Park and Ride and car pool from there. Please bring your own lunch and water.

Join us for this insightful venture, by sending Cal Ruleman (cruleman@usgs.gov 303-236-7804) your name, email, and cell phone number. We’ll have more details in the May newsletter and online.

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.)
