Here are other things we did this spring:

Hike to the Headcut











Why does stream assessment matter? Join an outing on Tuesday, April 4th, along Sonoita Creek above Patagonia Lake to discover a pristine part of the creek and brainstorm ways to preserve this un-eroded part of the creek from the devastation closer to the lake created by summer floods. Members of our stream assessment team will demonstrate some of the techniques we use to measure the health of the creek.

This hike is limited to twenty people – FOSC members– so sign up now. Patagonia Lake State Park Manager Colt Alford has graciously agreed to free admittance for our members, if you do not have a park pass.  Tell the ranger at the gate that you are with our hike. We will meet at the birding trail kiosk at 8:30 a.m. Please carpool if you can as parking is limited.

The hike itself is really just a walk of about a mile each way in the state park birding area. Bring sun protection, water, a walking stick if you choose, and binoculars. No dogs please.

RSVP  to gould226@hotmail.com for the hike to the headcut.
