The Moon held little interest for most scientists after its basic astronomic properties had been determined and before direct exploration appeared likely. Speculations about its internal structure, composition, and origin were only broadly constrained by cosmochemical data from meteorites and solar spectra, and by astronomic data about its size, shape, motions, and surficial properties. Most investigators who were active before the space age began in 1957 believed that significant new advances in lunar knowledge required acquisition of additional data. One analytical technique, however, was...

This publication presents an overview of the archaeology of the Central High Plains. The volume provides baseline information about the archaeology of the Bureau of Land Management's (BLM) Canon City Colorado] District, the V.S.D.A. Forest Service's Regions II and III and the BLM's Albuquerque New Mexico] District. This work describes the archaeology of portions of five states and represents a large geographic area ranging from the Continental Divide to the plains of Kansas and Nebraska. A major feature of this work is the fact that it is one of the first such projects that was jointly...

Between 1978 and 1999, excavations in arctic and western Alaska have revealed the presence of Paleoindians during terminal Pleistocene/early Holocene times, ca. 12,000 to 9500 years BP (Before Present). The Type Site for this cultural manifestation, the Mesa Site, is located on the northern flank of the central Brooks Range at N68 24.72 W155 48.02, amid rolling foothills that extend northward 40 miles to the Colville River. The site lies atop a mesa-like ridge that rises 180 feet above the floor of the Iteriak Creek valley, offering an unobstructed 360 view of the surrounding treeless...

This publication represents the latest Class I (History) to be written for the western slope of Colorado. Our three districts in this region of Colorado now have histories specifically for them. Such works provide a valuable and needed synthesis of history and literature for these areas and also gives our managers data that are used on a daily basis for land-use decision making. Multiple land use is a Bureau mission that is being met. Oil and gas, coal, oil shale and other energy minerals, not to mention rights-of-ways, grazing programs, recreation projects and land-use planning, are all...

This volume represents the fourth in a series of five Class I Overview histories prepared by the Colorado State Office, Bureau of Land Management. The purpose of these works is to develop a synthetic history of a given area in order to provide our managers and staff specialists with a baseline overview of the history in a district. We have prepared these documents district by district, and they are regularly used by BLM personnel for orientation, training, and literature searches by professional consultants. In addition, these Class I's are basic to the operation of BLM's Cultural Resource...
