A little-known territory is the Four Corners area, where the states of Utah, Arizona, New Mexico, and Colorado join. There are few roads in this area, and it is inhabited chiefly by Navaho Indians, still living in primitive conditions. It was while I was living in this region — maintaining a small school, a very active clinic, a chapel, and a sort of hostel for travelers passing through on horse or in wagon from trading posts or going from one hogan to another — that certain artifacts came to light.

The first points submitted for classification to H. Marie Wormington, of the Denver Museum, included Yuma, Silver Lake, and Pinto Basin types, among others. During the 1951-53 period, a large number of points were sent to Dr. Wormington. Many were points I picked up, but a good percentage came as the result of training Navaho shepherds and certain of my pupils to recognize the Pinto Basin types.
