The reconstruction of the Pueblo Culture of southern Nevada presented in the following pages, is based on data drawn from many sources. Chief among these is the wealth of undescribed archaeological materials recovered from the great ruins near Overton, Nevada, the Pueblo Grande de Nevada. The Pueblo Grande de Nevada, or Lost City, has been examined or dug into by many workers. The results of all this research have never been published except for a few progress reports. This report attempts to assimilate all the data gathered during these previous projects.
