Moreover, there are no records \r\nof Pacific Decadal Oscillation (PDO) variability, a major driver\r\nof decadal to multi-decadal climate variability for the region, \r\nolder than 1,000 years. Recent research on Lake Elsinore, however, \r\nhas shown that the lake's sediments hold excellent potential for \r\npaleoenvironmental analysis and reconstruction. New 1-cm contiguous\r\ngrain size data reveal a more complex Holocene climate history \r\nfor Southern California than previously recognized at the site. \r\nA modern comparison between the twentieth century PDO index, \r\nlake level change, San Jacinto River discharge, and percent sand \r\nsuggests that sand content is a reasonable, qualitative proxy for \r\nPDO-related, hydrologic variability at both multi-decadal-to-\r\ncentennial as well as event (i.e. storm) timescales. A depositional\r\nmodel is proposed to explain the sand-hydrologic proxy. The sand-\r\nhydrologic proxy data reveal nine centennial-scale intervals of wet \r\nand dry climate throughout the Holocene. Percent total sand values\r\n>1.5 standard deviation above the 150-9,700 cal year BP average \r\nare frequent between 9,700 and 3,200 cal year BP (n = 41), \r\nbut they are rare from 3,200 to 150 cal year BP (n = 6). \r\nThis disparity is interpreted as a change in the frequency of \r\nexceptionally wet (high discharge) years and/or changes in large \r\nstorm activity. A comparison to other regional hydrologic proxies \r\n(10 sites) shows more then occasional similarities across the region \r\n(i.e. 6 of 9 Elsinore wet intervals are present at >50% of the\r\ncomparison sites). Only the early Holocene and the Little Ice Age \r\nintervals, however, are interpreted consistently across the region \r\nas uniformly wet (>=80% of the comparison sites). A comparison to\r\ntwo ENSO reconstructions indicates little, if any, correlation to \r\nthe Elsinore data, suggesting that ENSO variability is not the \r\npredominant forcing of Holocene climate in Southern California.\r\n","author":null,"citation":"Kirby, M., S.
