“…Other paleotemperature proxy records from the Great Basin region often extend farther back into the Holocene than our record, but with less than annual resolution. These proxy archives, such as lacustrine and meadow sediment cores, packrat middens, and glacial moraine dynamics (Thompson et al 1994;Clark and Gillespie 1997;Smith and Betancourt 2006;Reinemann et al 2009) are in general agreement with our results, recording higher temperatures during the middle Holocene. Unfortunately, the other proxy archives lack the resolution to be effectively compared to our results in detail.…”

The instrumental temperature record is of insufficient length to fully express the natural variability of past temperature. High elevation tree-ring widths from Great Basin bristlecone pine (Pinus longaeva) are a particularly useful proxy to infer temperatures prior to the instrumental record in that the tree-rings are annually dated and extend for millennia. From ring-width measurements integrated with past treeline elevation data we infer decadal-to millennial-scale temperature variability over the past 4,500 years for the Great Basin, USA. We find that twentieth century treeline advances are greater than in at least 4,000 years. There is also evidence for substantial volcanic forcing of climate in the preindustrial record and considerable covariation between high elevation tree-ring widths and temperature estimates from an atmosphereocean general circulation model over much of the last millennium. A long-term temperature decline of *-1.1°C since the mid-Holocene underlies substantial volcanic forcing of climate in the preindustrial record.

“…Smaller glacial deposits with minimal to no vegetation and well-preserved moraines (Qrpm) are generally restricted to north-facing slopes and cirques above 10,000 feet elevation. These are products of both the latest Pleistocene Recess Peak and late Holocene Matthes (Little Ice Age) ice advances recognized elsewhere in the Sierra Nevada (Clark and Gillespie, 1996). High-elevation talus fields merge with these young tills and probably mainly grew during times of more abundant ice.…”

“…The late-Pleistocene Recess Peak advance, was first suggested as late-Holocene (Binnan, 1964), but evidence now indicates the advance occurred between 14.2 and 13.1 ka B.P. (Clark and Gillespie, 1997). Recess Peak glaciers were less extensive than the Tioga advance, with glaciers reaching lengths of about 2 km.…”

“…The glacial history of the region is relatively well known. Geologic evidence indicates at least five major glacier advances during the Pleistocene (oldest to youngest): McGee, Sherwin, Tahoe, Tioga, and Recess Peak (Blackwelder, 1931; revised by Clark and Gillespie, 1997). Multiple glacier advances occurred throughout the late-Tahoe and Tioga periods with the Last Glacial Maximum occurring 21 ± 2 ka B.P.…”
