Ever since Yuma points were recognized as being particularly ancient, Yuma County, Colorado has been a logical area of interest. Nevertheless, until 1941 the county had received scant attention from professional archaeologists, with the sole exception of a partial surface survey by Dr. E. B. Renaud. On the other hand, there had been considerable collecting by local residents, most particularly by Perry and Harold Andersen of Yuma, Colorado, who have amassed a large and valuable collection including numerous Folsom and Yuma points.In 1941 Yuma County was still liberally spotted with blowouts resulting from wind erosion of the sandy soil consequent upon the previous drought. Conditions were, for the archaeologist, optimal. Thanks to Dr. Donald Scott, who arranged that expenses be defrayed by the Peabody Museum of Harvard University, my wife and I were enabled to spend part of the summer and early fall in Yuma County and adjacent portions of other counties.

Having been brought up on monocular microscopes I find the omnipresent binocular systems a luxury. To support this viewpoint I'd like to suggest some benefits you may not have considered.Because I'm used to monocular viewing I sometimes use two different oculars, say 10X and 25X, in order to scan quickly to find an area of interest and then to examine the detail with higher magnification. Occasionally I use both oculars simultaneously and “concentrate” on either image to the exclusion of the other. A better way is to set the interocular distance at the extreme setting most different from your own interocular distance. By moving your head about a centimeter either way you can use either ocular.
