In June 1994, T. D. Berger and H. Khalaily conducted a surface collection on the colluvial slope immediately below the cave. The lithics contained Mousterian, Kebaran, and Natufian artifacts. In 1995, under the co-direction of T. D. Berger (University of New Mexico) and L. Grosman (Hebrew University of Jerusalem), the first season was spent cleaning the detritus and historical deposits, as well as excavating several test trenches to locate the extent of the prehistoric sediments. Natufian artifacts were found in a trench under the ashy historical accumulations. Since then, L. Grosman has conducted three additional field seasons at the site (1997, 2000, and 2001).
