The Colorado Scientific Society normally has spring and fall field trips.
Our No Moss Gatherings are short visits to interesting sites around the Denver area (from “a rolling stone gathers no moss”).

2023 Colorado Scientific Society Field Trips

We are working on several field trips at this time.

What are “No Moss Gatherings”?

Motto: “a rolling stone gathers no moss“.
These are usually half day trips in the Denver area.
Pete Modreski started these in the Spring of 2022, encouraging CSS members to get out after the Covid-19 shutdown.

South Park Overnight trip

Cal Ruleman, Peyton Jackson, Peter Barkmann, and Ned Sterne will lead this trip.
People can camp at Peyton’s ranch, near Hartsel on Saturday Night.

More details will be provided as they are available.
