Note: Due to the reduced, yet continuing presence of the Covid-19 virus, please continue to exercise good judgement and be respectful of others. If you do feel sick, we would advise that you please respect others health and not attend field trips.

IMPORTANT NOTICE FOR 2024: Due to the extreme drought conditions throughout Colorado, there is a greater than normal likelihood that wildfires may occur throughout the field trip season. Everyone is asked to keep current throughout the upcoming months regarding any active fires in the areas of our field trips. We will attempt to send out notices of area closures that affect a particular field trip, specifically to those who have signed up in advance for that trip. Hopefully we will not be affected, but field trip cancellations have occurred in the past, and could happen again.

Information about field trips is available to members only. If you would like to become a member, you can download a membership application form below. You must bring a completed application along with memberships dues to give to the trip leader. The deadline for inquiries is two weeks prior to the field trip. Do not mail checks or membership applications during the summer.
