Hampered by a late start and just an 18 day drilling window, Aspen’s effort to evaluate geothermal resources has been suspended. With a test hole at just 1,000 ft, no water has been discovered yet. The drilling came to a halt out of consideration for neighborhood noise concerns and the approaching ski season. A feasibility study in 2008 suggested that 90 – 140 degree water might be present, with >100 degree water the threshold for district heating applications. City officials have not yet determined if the project will resume in the spring. At the Eagle County Airport near Gypsum, Flint Eagle LLC is in the permitting process for a 4,000 ft test well to explore geothermal water in the Rio Grande Rift. The well will provide information on volume, temperature and chemistry which, if suitable, could provide heating and energy production options.
