The document is an "Autumn Alphabet" that provides examples of things found in Moreau Lake State Park for each letter of the alphabet. It encourages the reader to go out and find their own examples. For each letter, it lists a word beginning with that letter and often includes a short description, such as "A is for Autumn, of course!" or "B is for Beech, with leaves of gold." The alphabet highlights different plants, animals, landscape features, and activities commonly seen in the park during autumn.
