What's Hidden Beneath Your Feet?
Flowing Underground:
This may look like a dry spot, but water moves beneath your feet. Surface water sinks through this porous soil until it hits a hard rock layer, then it runs downhill toward the lake. A spring forms wherever this groundwater emerges.
Tracking a Spring:
Looking toward the lake you will see rows of cream-colored rock towers known as tufa. The towers reveal where springs once emerged beneath Mono Lake. (Remember, all the land you are walking over was once under water.) As the lake level dropped, the tufa towers were exposed and the springs that formed them dried up. |
