Our drilling and trenching failed to find saturated conditions anywhere within the thick colluvium except in boring 20 at the toe. Saturated conditions must exist at other places in the colluvium, for we noted a line of springs near boring 12 (pi. 1) and an ephemeral spring near boring 14. Boring 12 was flooded with surface water from the springs and provided no worthwhile data, but colluvium in borings 9,10,13, and 14 was unsaturated.
