In 1992, a 308.6 m core to bedrock was drilled on the Guliya ice cap in the far western Kunlun Shan on the Qinghai-Tibetan Plateau, China. The core was recovered using an electromechanical drill in a dry hole to 200 m and a thermal drill with an alcohol-water mixture from 200 m to bedrock (308.6 m). No hiatus was observed in the core, and the visible layers were horizontal throughout. The entire length of the frozen core was analyzed by cutting 12,628 samples for oxygen isotopic (d18O) measurements, 12,480 samples for dust concentrations, and 9,681 samples for anion Cl, NO3, and SO4 concentrations.
