Team Delta is committed to the geo-referencing and digitization of historical aerial photographs from Mt. Adams in Washington. With their operations based out of Portland, Oregon, continuing research is carried out to look into the hydrological effects of glacial fed streams.
[edit] Glacial Digitization
Ice (mostly in the form of glaciers) covers about 6.2 mile² (16 km²) of the mountain's upper cone and is fed by ample snow and rainfall every year. Water percolates through the very porous interior of the main cone and exits near the volcano's base as springs.
Glaciers cover a total of 2.5% of Adams' surface but during the last ice age about 90% of the mountain had glaciers on it. Most of the largest extent glaciers (including the Adams, Klickitat, Lyman, and White Salmon ) originate from Adams' summit ice cap. On the northwest face of the mountain is Adams Glacier, which cascades down a steep channel in a series of icefalls before spreading out and terminating at around 7000 feet (2100 m) elevation.
At the head of the Klickitat Glacier on the volcano's eastern flank, a mile-wide cirque (second in size among the Cascades only to Carbon Glacier on Mount Rainier) is fed by two smaller glaciers from the summit ice cap and terminates around 6000 feet (1800 m). These glaciers are being digitized from the years 1907, 1955, 1958, 1969, 1998 and 2000. Surface areas from glaciers become indicaters of climatic changes, making them very useful tools for predicting future climatic trends.
