  <Summary>
    <Abstract>Continuous, high-resolution  d18O records from cored sediments of Pyramid Lake, Nevada,  indicate that oscillations in the hydrologic balance occurred, on average, about every  150 years (yr) during the past 7630 calendar years (calyr). The records are not stationary;  during the past 2740yr, drought durations ranged from 20 to 100yr and intervals between  droughts ranged from 80 to 230yr. Comparison of tree-ring-based reconstructions of climate  change for the past 1200yr from the Sierra Nevada and the El Malpais region of northwest  New Mexico indicates that severe droughts associated with Anasazi withdrawal from  Chaco Canyon at 820calyrBP (calendar years before present) and final abandonment of  Chaco Canyon, Mesa Verde, and the Kayenta area at 650calyrBP may have impacted much of the  western United States.  During the middle Holocene (informally defined in this paper  as extending from 8000 to 3000calyrBP), magnetic susceptibility values of sediments  deposited in Pyramid Lake&apos;s deep basin were much larger than late-Holocene (3000-0calyrBP)  values, indicating the presence of a shallow lake. In addition, the mean d18O value of  CaCO3 precipitated between 6500 and 3430calyrBP was 1.6 less than the mean value of  CaCO3 precipitated after 2740calyrBP. Numerical calculations indicate that the shift  in the d18O baseline probably resulted from a transition to a wetter (&gt;30%) and  cooler (3-5°C) climate. The existence of a relatively dry and warm middle-Holocene climate  in the Truckee River-Pyramid Lake system is generally consistent with archeological,  sedimentological, chemical, physical, and biological records from various sites within  the Great Basin of the western United States.  Two high-resolution Holocene-climate records  are now available from the Pyramid and Owens lake basins which suggest that the Holocene  was characterized by five climatic intervals.  TIC and d18O records from Owens Lake indicate  that the first interval in the early Holocene (11,600-10,000calyrBP) was characterized by a  drying trend that was interrupted by a brief (200yr) wet oscillation centered at 10,300calyrBP.  This was followed by a second early-Holocene interval (10,000-8000calyrBP) during which  relatively wet conditions prevailed.  During the early part of the middle Holocene  (8000-6500calyrBP), high-amplitude oscillations in TIC in Owens Lake and d18O in Pyramid Lake  indicate the presence of shallow lakes in both basins. During the latter part of the middle  Holocene (6500-3800calyrBP), drought conditions dominated, Owens Lake desiccated, and  Lake Tahoe ceased spilling to the Truckee River, causing Pyramid Lake to decline.  At the beginning of the late Holocene (~3000calyrBP), Lake Tahoe rose to its sill level  and Pyramid Lake increased in volume.</Abstract>
