Trinity Street Lobby Field Trip Pick Up, Austin Convention Center
Organizer:
J. Hayley Gillespie
The Barton Springs Salamander (Eurycea sosorum) is a permanently aquatic endangered salamander endemic to four freshwater springs located in Zilker Park near downtown Austin, Texas, one of which is operated as a public spring-fed swimming pool. Participants will be introduced to the natural history, ecology, evolution and conservation issues for this species by (1) a self-guided tour of the City of Austin’s ‘SPLASH Into the Edwards Aquifer’ exhibit, an educational exhibit about environmental issues on the Edwards Aquifer (2) a City of Austin biologist-led tour of the four freshwater springs that are host to the only known populations of the Barton Springs Salamander in which participants will get to see wild salamanders in their natural habitat (3) swimming and/or snorkeling in Barton Springs Pool.
Swimming is weather permitting.
Tour of Upper Barton Spring is dependent upon adequate spring flow – this site often goes dry in the summer. Barton Springs Pool is open until 10pm, and it is a popular Austin tradition to go night swimming.
We will be there 5 days before the full moon so there should be plenty of waxing gibbous moonlight to swim by if you’d like to stay longer and arrange your own transportation back to the Convention Center or your hotel. Return on your own on Saturday, August 13, 2011 at 9pm for the great Austin tradition “Howl at the Moon” full moon swim party at Barton Springs: http://365thingsaustin.com/2010/08/24/236-full-moon-swim-at-barton-springs-pool/, and http://www.youtube.com/watch?v=LfUN5jf0xUw&feature=related

Equipment and Attire: Please bring a swimsuit & towel if you would like to swim at Barton Springs Pool and mask/snorkel if you like to snorkel. We will be walking approximately .3 miles/.5km upstream of Barton Springs Pool along a natural gravel and limestone path to visit Upper Barton Spring. From Upper Barton Spring we will walk approximately .68 miles/1.1km to Sunken Garden Spring. Tennis shoes or sport/aqua sandals are recommended for this part of the tour, the hike is not strenuous but is mostly unpaved and has some stairs, shoes may get wet! Austin summers are HOT, so bring a water bottle, sunscreen and breathable clothing!
