As part of the Professional Development Workshop at Calhoun Community College, the Department of Natural Sciences conducted the third annual Spring Wilderness Pilgrimage in March 1989, a week-long environmental awareness field trip for faculty and staff. Designed as a study of the plants and animals on a barrier island off the coast of Florida, the trip included nature hikes, a shrimp feast, photomicroscopy of marine life, mollusk identification, seashell collecting, and leisure time on the beach. This guidebook, for use by field trip participants, provides information on the flora and fauna studied during the trip, and includes background information, maps, tide charts, and other reference materials. The guide includes the following components: an article describing typical encounters and experiences on Dog Island; a map outlining the travel route of the group; a detail map of the island; an itinerary of activities; a list of group participants; tide tables and geographical coordinates; and lists of visible astronomical phenomenon, birds, mollusks, and plants. The section on mollusks discusses shell identification, classification keys for shell families, shell tips, live clam observation, and mussel (clam) dissection. An extensive section on plants, provides a key to Dog Island plants, a checklist of common plants on the island, and divisions of plants by species, type, distinctive features, flowering season, and habitat. The guide concludes with references and a passage from Oliver Wendell Holmes's poem "The Chambered Nautilus." (JMC)
