LaMotte Sandstone Barrens

Points of Interest:

  • See ancient gnarled post and blackjack oaks seemingly growing from sandstone rock.
  • Look for the exquisitely camouflaged lichen grasshopper on the lichen studded rocks.

Natural Features:

This area is formed on outcrops of LaMotte sandstone, a geologic formation formed in the Cambrian period over 550 million years ago. These exposed rocks are covered with extensive lichens and mosses with scattered patches of vascular plants.

Some of the interesting plants found here include fame flower, which stores moisture in succulent leaves. All creatures making a living on this glade have developed mechanisms to tolerate or avoid the hot, dry conditions. Some wildflowers such as lance-leaved coreopsis, yellow star grass and potato dwarf dandelion bloom and set seed in the spring when moisture is still available on the glades. Other species such as Willdenow’s croton have narrow leaves covered with hairs that help prevent moisture loss.
