Remarks:

When first uncovered, this installation appeared to be a compact earth surface, like Surfs 6, 10, & 16; it was only a remnant of a surface, as all edges seem to be broken off; the poss existed that it was connected to Surf 16 (which runs along the E balk) at the installation's N-most point, however, the connection was not clear; Surf 16's S-most point also could have been a later resurfacing of Surf 16; Installation 15 is at a higher level than any of the surrounding loci; in the N half of the installation is a cup-like depression whose surface is continuous with the rest of the installation surface; it is 10 cm deep & 30 cm in diameter; it may have been a small storage cup, or used for holding or preparing some liquid or food; when the installation was sectioned, it became clear that it was made of plaster & stones: beneath 1 cm of the compact earth surface was a layer of crushed limestone plaster with a sandy texture which cannot be broken down into lumps; beneath & throughout the plaster are smaller & then (deeper down) larger limestone cobbles (5-10 cm); these in turn are set into the hard compact material of L 22; a cross-section through the installation would have a concave shape; the section clearly showed that the installation is a part of Surf 16, the separation being a vertical line; the surfaces are coplaner
