In 2001, I discovered what I believe to be Rancholabrean rubbing rocks on California’s North Coast (Parkman 2002a, 2002b, 2002c).

(1) These are features that I believe were used for grooming by now-extinct Ice Age megafauna such as .

The single deep excavation unit revealed quarry debris to 220 cm, and several possible hammerstone spalls were found at 200-220 cm.

The auger test made in the same unit recovered what may prove to be small pieces of quarry shatter to 340-350 cm.

(2) The following is an update on some of the progress that we have made to date as well as our plans for future research.

Archaeological Investigations at Jasper Rock Since 2003, archaeological excavations have been underway at Jasper Rock, a highly-polished jasper outcrop with evidence of past quarrying.

(4) It is possible (but certainly not proven) that the cultural component (or components) found between 100-180 cm at Jasper Rock is contemporaneous with the early Holocene occupations at nearby Duncans Landing Rockshelter.

At Jasper Rock, additional cultural components may exist from 180-350 cm.

An additional component (or perhaps components) exists from about 100-180 cm, a zone characterized by compacted yellow loam subsoil.During the summer and fall of 2003, one of the units was expanded into a 4x4 m block exposure (Fig. The spring 2004 crew worked on the 4x4 m exposure, and also excavated three 1x1 m units at CA-SON-365/H, a shellmidden located 100 m south of the jasper outcrop.The surface of the shellmidden had revealed debitage of a material similar to the outcrop.Thus, we chose to excavate the shellmidden in order to determine its connection, if any, with Jasper Rock.By the end of fall 2003, a single 1x1 m unit located within the larger 4x4 m exposure at Jasper Rock had been excavated to a depth of 280 cm.

The rocks are located on the coast of Sonoma County about 75 km north of San Francisco, within Sonoma Coast State Beach, a unit of the California State Park System.

  1. Just wondering if you have picked numbers from a range than is not used by the cc companies and thus guaranteed to be invalid or if you’re just assuming that the chances of a random credit card number and a random expiry date matching up are as slim as to be virtually nil.
