OAS opens up field trip and event sign-ups on a rolling basis. Most local area trips open up at the beginning of the month before the trip (e.g., an October 15 trip signup would open up at the beginning of September). Some overnight or long-distance trips open up earlier to give people time to sign up and make their own travel plans. If you have questions about a specific event, please contact the event lead listed under Activities.
OAS events have varying costs. Some are free. Even if you are attending a free field trip, you MUST sign up in advance in order to let us know how many people plan to attend and to fill out the participant liability release form.
You won’t be able to see all the upcoming events until you indicate whether you are a member of OAS or not.
We know that some people like to sign up for trips with a friend or family member. You can use this form to sign up more than one person at a time, but all participants must provide emergency contact information (which could be the same person), and agree to their own participant liability release form.
