I'm not going to undo the edit, but there is indeed a word "degassing" See [1]

At risk for merge?[edit]

Since we included the recreational use shouldnt we say it is part of a larger artical so no one who is stupid enough tries merging the mountain with the resort. they are two complete different subjects!!! —Preceding unsigned comment added by TJMcDJ (talkcontribs) 20:28, 25 May 2010 (UTC)

how much is that in gallons of used gasoline?[edit]

For the global warming alarmists (and non-alarmists) a conversion of the amount of CO2 released by this mountain into car-culture terms (as much as a day's automobile usage in Dallas? All Texas? Plano?) would be very nice. (talk) 17:01, 22 November 2010 (UTC)

External links modified[edit]

Hello fellow Wikipedians,

I have just added archive links to one external link on Mammoth Mountain. Please take a moment to review my edit.

Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

Carbon dioxide outgassing was known about 50 years ago in 1970[edit]

Back in 1970 I was a college geology student. My geology instructor informed us that there was renewed volcanic activity in the Mammoth Mountain area, including carbon dioxide gas release, a rise in underground temperature, and local seismic activity. It had also been noticed that the forest was dying in certain areas. On summer break that year, a friend and I went to the area and observed the dying trees and the damage to the access road to the nearby Devil's Postpile National Monument where we camped. The local seismic activity had been enough to cause a slight change in ground surface profile in perhaps a fifty acre area so the road had to be repaired in places to be drivable. We immediately noticed that the conifer trees in certain areas were all yellowed and dropping their needles. Linstrum (talk) 04:36, 28 March 2020 (UTC)

Could that have been a different area than Horseshoe Lake? Figure 2 of Sorey[1] shows tree kill areas north of Mammoth Mountain, near the Main Lodge. The fumarole on the north flank of Mammoth apparently became active in 1989, while remote sensing showed that the tree kill areas showed up between 1983 and 1993. — hike395 (talk) 05:53, 28 March 2020 (UTC)
