This catalogue describes and illustrates ten centuries of prehistoric south-western pottery, most of it from the Four Corners country, where New Mexico, Colorado, Utah, and Arizona meet. The pottery shown here was collected by pioneering southwestern archaeologist Earl H. Morris (1889-1956). Since Morris's death, his collection has been housed in the University of Colorado Museum. Most of the vessels in the Morris Collection are illustrated here. While the catalogue concentrates on pieces from the area between Chaco Canyon and Mesa Verde, a few pots from other regions demonstrate the variations in prehistoric pottery making in the Southwest. Morris's comments from his own catalogue of the collection are included. In addition to describing the vessels, he tells how each came into his possession -- where he found it or what he traded for it. The Listers have added information about type, size, and provenience. Originally published in 1969, this catalogue has proved its value to ar-chaeologists, collectors, and readers interested in the history of southwest-ern archaeology.
