Mammoth carbon-belching slows

MAMMOTH MOUNTAIN, Calif. – The emissions of carbon dioxide from Mammoth Mountain have been decreasing.

The carbon dioxide was vented after a flurry of earthquakes in 1989, opening cracks. Both odourless and invisible under normal conditions, the carbon dioxide killed three ski patrollers from Mammoth Mountain last year.

However, the amount of carbon dioxide emitted by Mammoth mountain has declined 80 per cent since the mid-1990s, reports The Sheet. Scientists with the Sierra Nevada Aquatic Research Lab say the cause of the decline is not known: possibly because the size of the underground reservoir of magma is shrinking or possibly because the fissures are resealing themselves.


Solar panels installed

VAIL, Colo. – Solar collectors are being installed on two buildings located atop the Vail Village Parking Structure.

In addition, town officials are replacing incandescent light bulbs in the Colorado Ski Museum with compact fluorescents.

Together, the two projects are costing the town $25,000. The payback on the investment is calculated at 10 years.

Town officials chose the very conspicuous public buildings — an information centre and the transportation centre — in an effort to lead by example, said Bill Carlson, the town’s environmental health officer. “We hope to encourage businesses and private property owners to research alternative energy uses that they might install on their property,” he said.

Last summer, the town bought renewable energy credits equal to the total use of the town government, about 20 million kilowatt hours. The increased cost was $12,000 per year.

The town is also re-roofing the buildings atop the parking structure with new synthetic slate shingles. At least one of the buildings has shake shingles. Again, the effort is to lead by example. Responding to heightened worries about the potential for wildland fires, the town in the last year required new roofs and those being replaced to use the non-combustible shingles.


Ban on cyanide mining appealed

SUMMIT COUNTY, Colo. – As expected, Summit County’s ban on cyanide-heap-leach mining is being appealed to the Colorado Supreme Court. The ban had been ruled unconstitutional by a district court, but that ruling was overturned by the Colorado Court of Appeals.
