在33.6 ~ 26.1 ka期间，加州东南部的Searles湖经历了6个主要的扩张和收缩周期。这些事件的U/Th年龄与准周期interstadial事件在冰芯从首脑会议，格陵兰岛的年表的比较表明，低水位的事件在Searles湖是同步的interstadial事件在首脑会议。这两种现象可能与全球水文循环强度的变化有关，这种变化是由大西洋温盐环流的振荡驱动的。
During the interval 33.6 to 26.1 ka, Searles Lake in southeastern California went through six major cycles of expansion and contraction. A comparison of U/Th ages for these events with the chronologies for quasi-cyclic interstadial episodes in the ice core from Summit, Greenland, suggests that the episodes of low water at Searles Lake are synchronous with the interstadial episodes at Summit. The two phenomena may be linked by variations in the strength of the global hydrological cycle, driven by oscillations in the Atlantic Ocean thermohaline circulation.
