The Intermediate also saw the first local use Of <br />steatite. Steatite is a soft, easy to work material and was <br />used for a wide variety of purposes, ranging from cooking <br />utensils to items of personal decoration. The steatite was <br />imported from Santa Catalina Island, proof that the Intermediate <br />people had mastered local open ocean travel. <br />The final phase of native culture is known as the Late <br />Prehistoric Period, and it began around A.D. 750. The Late <br />Period is characterized by changes in mortuary practices and by <br />rather dramatic increase in the use of shell for decoration and <br />functional tools. Projectile points become smaller still and <br />are generally more finely worked than in the preceding era. <br />Pottery appeared in some quantity near the end of the period. <br />The local chronology, as it is presently understood, is <br />summarized in Table 1. which appears on the following page. The <br />above description and Table 1 are based primarily on koerper and <br />Drover 517831. <br />Archaeological Research: On 14 October 1486 a literature <br />review was accomplished at the Archaeological Survey, University <br />of California, Los Angeles, the repository of archaeological <br />data For Orange County. the records of the Anthropology Museum, <br />California State University, Fullerton had been previously <br />examined. <br />the literature review established that the study area had <br />never been examined for archaeological remains and that no <br />archaeological sites had been recorded in the immediate <br />vicinity. Essentially all of the study area had been built -up <br />prior to the introduction of requirements for pre - construction <br />archaeological mitigation. <br />During the field work for this Project aL1 open areas <br />fronting on Bristol Streek were examined for archaeological <br />remains. Such area amounted to approximately 5% of the total <br />12 <br />75C -760 <br />
