Colorado's Pawnee Grasslands are well suited for a wide range of academic study, from astronomy to zoology. Designed for educators and youth leaders seeking to integrate an alternative experience into their curriculum or recreation program, this guide is intended to give leaders of excursions to the Grasslands a sense of what's out there and some ideas on how to creatively use the environment. The guide presents information on the: Grasslands as a learning environment; archaeological sequence in the Central Great Plains; recent American Indian history; the Buffalo Range from 1850 to 1880; migration and settlement patterns in Northeastern Colorado; settlement dates of selected towns in Northeastern Colorado; white man and the Grasslands; geology of the Pawnee Grasslands--soil, climate, precipitation and temperature, important grasses, and birds and mammals; development of a unit--an interdisciplinary approach to the Grasslands, activity sites, equipment, safety, food and water suggestions, nutritional components in the edible portion of one pound of food, sample ideas for experience-oriented interdisciplinary Grasslands units; and Grasslands information sources covering anthropology, environment, Indian history, literature, outdoor skills/logistics of field trips, and pioneer history.
