The Sloan Digital Sky Survey has obtained a few hundred square degrees of photometric scan data, in five bands (u',g',r',i',z'), which we use to identify clusters of galaxies. We present the distribution of galaxies to r' = 21.5; this gives us 106 galaxies over a contiguous region of 150 square degrees. We present here different methods of finding clusters and a comparison of the techniques, and preliminary characteristics of these clusters.
