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.
