After some fifty years of neglect, Ami's trench itself was nearly filled with backdirt  from the original excavation that had washed in. The first task, then, was to remove this overlying material to expose the original trench limits. Much of the 1987 season was spent removing the fill in Sector II, where it became apparent that the earlier excavators had opened up a considerable lateral excavation toward the west. All of the backdirt was dry-screened and several thousand lithic artifacts were recovered. This material, though without any archaeological context, served as a study collection and, indeed,was useful in demonstrating the nature of excavator bias in Ami's collections.
