Looking north from Wildcat Mtn. Bob Raynolds (Denver Museum of Nature and Science) discusses how the Arapahoe conglomerate marks the start of the Laramide Orogeny in the Denver Basin. The Laramide Orogeny raised up the Rocky Mountains starting about 75 million years ago. Bob Raynolds was the Colorado Scientific Society President in 2018 and continues to be an active member. — Looking north from Wildcat Mtn.

We use donations to supplement funds from membership dues to fund our meetings, field trips, and the CSS grants that help earth sciences students with their research projects every year.

Colorado Scientific Society Meetings

We hold monthly meetings from September through May. (Many of our members do field research during the summer.)

Meeting presentations include: Geology, Paleontology (e.g. dinosaurs), Space Science (e.g. evolution of the solar system and Mars once had rivers and lakes), Ecology, and more.

Colorado Scientific Society Field Trips

We usually have about two one or more day field trips each year. We also have a few shorter half day trips called “No Moss” gatherings, as in “a rolling stone gathers no moss”.

Examining the Fountain Formation at Red Rocks on March 30, 2024. It consists sandstones and conglomerates interbedded with dark maroon mudstones deposited in alluvial fans along the the east side of the Ancestral Front Range about 300 million years ago. This was a No Moss Gathering.

Our field trips are open to the public and are often free. Look at our Home and Upcoming Field Trips pages to see coming field trips.

Student Research Grants

We make over $10,000 in grants to assist students in their earth sciences research every year. We make grants to multiple students to help offset their research expenses, as opposed to a larger grant to a single student.
See the Colorado Scientific Society – Student Research Grants page for details about our student research grants.
