Cover Image Credits: Images, clockwise from top left: climate model (CNRM-CM5) predictions of the change in precipitation during the Last Glacial Maximum relative to modern (after correction for model bias) shown in comparison to various paleoclimate archives, including soil, speleothems and pluvial lakes. Paleoclimate sites are: Diamond Valley, Nevada (DV), Newark Valley, Nevada (NV), Fish Lake Valley, Nevada (FL) and Barstow, California (BA), Wind River, Wyoming (WR); vein calcite, Devils Hole, Nevada (DH); deep vadose zone opal, Yucca Mountain (YM); speleothem, Cave of the Bells, Arizona (COB), Lake Bonneville, Utah (LB); Lake Lahontan, Nevada (LL); Lake Newark, Nevada (NV); Lake Diamond, Nevada (DV); Lake Jakes Lake, Nevada (JL); Lake Manly, California (LM) and Searles Lake, California (SL) (figure from Maher and others, p. 821, this issue); photograph of abandoned paleoshorelines in Diamond Valley; soil pit in Newark Valley, NV sampled for pedogenic carbonate/opal; and photomicrograph of a cross-section of a layered soil carbonate/opal clast coating about 5 mm thick (see Maher and others, this issue, p. 821).
