Believe it or not none of these pictures were taken under water on a tropical coral reef. Presque Isle's shoreline of trees, shrubs, and grasses plays host to a different kind of reef, not a coral reef but instead a rich & diverse array of lichens, mushrooms, fungus, & mosses that thrive and feed on the rich and moist Lake Erie air. These microcosms are a must see for all park explorers with the patience to slow down and look closely. Always remember that these are very delicate living organisms, and as such they have the same rights as you and I. Be careful not to damage or disturb them as you observe their splendor.
