Saturday, february 14, 8am-11:30am, Dane Smith - Backdoor Cave and Backdoor Spring
|
Join SOS staff field guides on a guided hike of the crush-worthy upper portions of the Barton Creek Greenbelt Trail. Follow your heart (and your guides!) to Backdoor Spring and Backdoor Cave, two hidden gems of the Edwards Aquifer recharge zone. Backdoor cave is one of the last un-gated caves in Austin, and--much like true love--it is hard to find. Don't worry, SOS will play matchmaker so you can get into a situationship with all things cavey, karst, and limestone. Along the way we will learn about local flora and fauna and flirt with basic aquifer science. Have fun exploring and fall head over heels for Barton Creek, one of the last pristine waterways of Texas, and the beloved Greenbelt, one of Austin's crown jewels of parkland.Word of warning: You may just find your soulmate on this hike!
