对法夫尔湖（内华达州红宝石山脉北部的一个高海拔冰斗湖）的沉积物岩心进行了多代理分析，并提供了约7600年地方和区域环境变化的记录。数据表明，当当地气候比现在更温暖和/或更干燥时，湖泊水位在 7600 到 5750 cal a BP 之间较低。有效湿度在 5750 calyr BP 之后增加，并保持相对湿润，并且可能较凉爽，直到大约 1000 年。 3750 卡路里每年血压。结果表明，气候总体干燥，但气候变化也有所增加，从 3750 到 1750 卡路里年BP，此后有效湿度增加。法夫尔湖代理数据发生重大变化的时间与大盆地几项古气候研究中记录的时间大致相同，这表明区域气候对当地条件的控制以及高海拔和低海拔地区的类似反应。
Multi-proxy analyses were conducted on a sediment core from Favre Lake, a high elevation cirque lake in the northern Ruby Mountains, Nevada, and provide a ca. 7600 year record of local and regional environmental change. Data indicate that lake levels were lower from 7600 to 5750 cal yr BP, when local climate was warmer and/or drier than today. Effective moisture increased after 5750 cal yr BP and remained relatively wet, and possibly cooler, until ca. 3750 cal yr BP. Results indicate generally dry conditions but also increased climatic variability from 3750 to 1750 cal yr BP, after which effective moisture increased. The timing of major changes in the Favre Lake proxy data are roughly coeval and in phase with those recorded in several paleoclimate studies across the Great Basin, suggesting regional climatic controls on local conditions and similar responses at high and low altitudes.
