Final day for cave tours is Sept 22. The caves and visitor center will be closed for the winter season beginning Sept 23. The park will re-open in the Spring.
On the trail leading to the cave, crusty red, green, grey, and orange lichens can be seen growing on bare rock. As you see them, please do not attempt to remove them because they grow at extremely slow rates. On average, they will enlarge 0.1 to 1 millimeter a year.
Lichens are composed of both fungus and algae that live together in a beneficial relationship. The alga provides food for the fungus, and the fungus retains water for the algae. By helping each other out they form lichens that can live in extreme environments
Lichens are useful in many ways. Humans use them to create color dyes and perfumes. Small insects create shelters and nests within them. Lichens are also partially responsible for the initial soil break down after disasters such as slope movement.Lichens are indicator species, meaning that they indicate whether or not the environment is healthy. They are extremely sensitive to air pollution and will not grow where there are too many pollutants in the air. For this reason, scientists use lichens to measure the degree of health in many different environments.
Did You Know?
Timpanogos Cave is known for its high concentration of helictites - a spiraling cave formation that seems to defy gravity. Helictites are formed when calcite crystals and dissolved impurities are forced out of a tiny central canal in the helictite by hydrostatic pressure.
