"abstract": "Ice-thickness measurements critical for flood and mudflow hazard studies are very sparse on Cascade Range (North America) volcanoes. Helicopter electromagnetic (HEM) data collected to detect hydrothermal alteration are used to determine ice thickness over portions of Mount Baker and Mount Adams volcanoes. A laterally continuous inversion method provides good estimates of ice <100 m thick over water-saturated and altered regions where the resistivity of the basement is <200 \u03a9m. For areas with ice overlying fresh, resistive rocks with small resistivity contrasts between ice and rock, ice thickness is not well resolved. The ice thicknesses derived from HEM data are consistent with the previous drillhole data from Mount Adams and radar data from both volcanoes, with mean thicknesses of 57 m for Mount Adams and 68 m for Mount Baker. The thickest ice on Mount Baker rests on the gentle lower slopes whereas the thickest ice at Mount Adams lies on the flat summit. Ice volume calculations suggest that Mount Baker contains \u223d710 \u00d7 106\u00a0m3\u00a0of ice in the HEM survey area, with a crude estimate of \u223d1800 \u00d7 106m3\u00a0for the entire volcano. Ice volume on Mount Adams is 65 \u00d7 106m3\u00a0in parts of the HEM survey area and \u223d200 \u00d7 106m3\u00a0overall.",
