It's part of an effort to buy the area and turn it into public land. The group, Friends of Rocky Glen started at Forest Park Nature Center to learn more about Rocky Glen.
It's a geological site off Kickapoo Creek Road, and there's some history there too. The site contains what's left of old coal mines and ancient rock formations.
David Pittman, president of Friends of Rocky Glen said the group needs to raise thousands of dollars, but that it will be worth it one day if it becomes a public park.
"For the folks who have grown up here this is family, this is our story. It's a piece of our history, coal mining history that really deserves a place to talk the story," Pittman said.
Friends of Rocky Glen leads free hikes every month, visit their website for more information.
