Area Description: As you continue on this shady trail, you soon come upon a small, but beautiful boulder field. This is a great moment to appreciate the stunning and varied geography of Wind Cave National Park. Also worth discussing is the explosion of color the lichen put on in this area. From the neon lime green, to the soft blue green that blends in with the local sage, these lichen can be found in abundance all over the park. These lichens are important for another reason. Due to their sensitivity to air pollution, lichens are seen as a sign of very clean air. As the interpretive station up on the top of Rankin Ridge states, Wind Cave is a Class 1 Airshed which is the cleanest designation possible.

Recommended Student Activity:
Ask the students who owns a National Park. The students? Parents? Rangers? Everyone!
Have students talk about what would happen if everyone that walked on this trail, picked up a rock and took it home.
Ask kids to come up with ideas on how they can help protect National Parks either during a visit or from home.
