1979-80 Marmot Glacier Survey Map Download 1979-80 Marmot Glacier Survey Map (5MB) 1977-1981 Annual Ice Ablation (Melt)     Jul 1978 Marmot Glacier - Looking South 1 April 1979 - J. Ellis at Station A with Theololite at toe of Marmot Glacier, looking South Steve Walti on 2 Aug 1979 with Theodolite Tripod, Station B, Marmot Glacier, looking NE A high-resolution, near-nadir DigitalGlobe Quickbird (0.6 m pan pixels)or GeoEye IKONOS (1 m pan pixels) satellite image would enable this 1979-80 survey map to be georeferenced and loaded into a GIS. Alternatively, orthorectified aerial photographs would enable georeferencing of this survey map. The Theodolite and Stadia data were processed and coverted a format appropriate for map generation with programs J. Ellis wrote for a Texas Instruments hand-held calculator in the early 1980's. If earth scientists were to return to this landform and acquire new x, y, z survey points using GPS or theodolite/stadia, then surface changes could be quantified over the past ~30 years, and models developed that correlated Trans Alaska Pipeline System (TAPS) weather records from Atigun Pass and Pumping Stations with landform changes.  In addition, volumetric changes could probably be modeled.
