The Lucy site in the Estancia Valley of central New Mexico promises to be an important locality for Early Man. Excavations were conducted there in the summer of 1954 as part of the University of New Mexico Field Sessions, directed by Frank C. Hibben. Much of the field work was done by Thomas B. Hughes and William B. Roosa, who acted as foreman. Other students who worked at the site are Erica Child, George Hopkins, Charles McNutt, Stewart Peckham, Octavio Romano, Russell Schorsch, and Gretchen Steiner.

The Lucy site was discovered by K. W. (Sambo) Kendall of Willard. It consists of a series of sand blowout areas south of Lucy. The site is in the head of a broad valley well above the shoreline of Pleistocene Lake Estanc'a and appears to have been a series of former ponds or springs. The Estancia Valley, especially around Willard, has a great many blowouts which contain early types of projectile points.
