- Author(s): Parkman, E. Breck
- et al.
The occurrence of cupule petroglyphs in the Diablo Range of central California was recently reported (Parkman 1986). In that discussion, special attention was given to cupule occurrences in the northern portion of the range. Since that time, other important data have become available concerning cupule occurrences in the southern portion of the Diablo Range. This paper is a brief discussion of those data.
