Bluebonnet Swamp Nature Center will host its sixth annual Rockin’ at the Swamp event from 9 a.m. to 4 p.m. Saturday at Bluebonnet Swamp Nature Center, 10503 N. Oak Hills Parkway.

The event allows visitors to explore geology and includes activities and displays about rocks, gemstones, minerals and fossils. Hobbyists will conduct hands-on exhibits, and vendors in the Rockhound Market will sell gemstone jewelry, rough and polished mineral specimens, fossils and more, a news release from the center said.

The event will feature a “Gold” Mine, a Treasure Trail, stone crafts, a rock-climbing wall, a fossil quarry and event souvenir buckets. At the “Gold” Mine people can hunt pyrite specimens for their collection, the release said. At the day’s end, children, ages 12 and younger, can search for “gold” in the Kids Gold Rush.

Along the Treasure Trail, experienced fossil hunters and beginner rock enthusiasts will take to the trails to hunt for stations, where they will collect specimens for gemstone identification cards, the release said.

Children and adults can produce one-of-a-kind pet rocks at the stone craft corner. Those attending can climb the rock wall and get their hands dirty in the fossil quarry while hunting for fossil crinoids, shells and shark teeth, the release said.

Admission is $4 for children, ages 3-17; $5 for adults; $2 for Bluebonnet Swamp Nature Center pass holders; and free for children, ages 3 and younger.
