To paraphrase the introduction, this glossary of natural terrain features is intended as a reference for military personnel and others who may use terrain studies. It also many serve as a guide to producers of Engineer terrain studies by standardizing and restricting the use of technical terms. It includes terms from many fields including physical geography, geology, hydrography, galciology, botany, and pedology. This is an alphabetic list of terms keyed to three appendices. The appendices are line drawings illustrating various sorts of terrain features. Where a term is shown on one of the appendices the number of the appendix and the coordinates where the feature appears on the appendix are given. Note that Page 22 in the copy digitized was missing. That page covered terms between “Creek” and “Debris.”
