Supplemental Information


 >Station locations: Station locations and elevations for the weather measurements generated or utilized in this study.
 >On-Ice and Off-Ice weather stations: Instrument readings from the Susitna Glacier "Off-Ice" weather station and the West Fork Glacier "On-Ice" weather station. The West Fork Glacier On-Ice station "floats" on the ice surface and moves down as the surface ablates. Note: "NaN" values throughout this table indicate that the measurement was not taken or was not applicable.
 >Ice temperatures at the On-Ice station: Thermistor temperature measurements (degrees C) near the West Fork Glacier On-Ice weather station. Sensors are labeled with their height/depth relative to the ice surface at installation. These depths change over time as the surface ablates.
 >Simple weather stations, including soil temperature: Readings from 26 stations installed around the basin to measure air temperature and relative humidity. A subset of these stations also measured precipitation and soil temperature.
 >Soil temperature measurement depths: Soil temperature measurement depths (m) at nine simple weather stations.
 >Mass balance - point: Point mass balance data in water equivalence (w.e.) from earlier work (Clarke and others, 1985) and our work. Note that the year used here is the mass balance year and not calendar year. The mass balance year 2012 corresponds to winter of 2011/2012 through the end of the summer of 2012.
 >Mass balance - radar: Winter mass balance data from helicopter-borne snow radar. Units are meters of snow water equivalent (SWE). For each glacier, the data were binned into 50-m elevation bands and then averaged. Standard deviation within each bin is also given.
 >Time lapse: Time-lapse videos from the cameras near the On-Ice (West Fork Glacier) and Off-Ice (Susitna Glacier) weather stations. The images used in these videos were captured at 10 a.m. local time. The camera at the On-Ice weather station started April 18, 2013, and ran until September 5, 2013. The camera at the Off-Ice weather station started on July 17, 2013, and ran until September 26, 2013.
 >Snow depth: Snow depth and density measurements between 2012 and 2014.
 >Soil pits: Observations from soil pits.
