Granite outcrop habitats provide great butterfly viewing. Bring a digital camera to record these incredible creatures. A ranger will point out wildflowers that bloom on the rock outcrop and species that utilize their nectar. We will look for Zebra Swallowtails, Black Swallowtails, Juniper Hairstreaks, and possibly a giant Yucca Skipper. Register in advance. $7 plus $5 parking. 770-389-7801.
