These two Google Earth images are attempts to duplicate the photo of the unknown mountain shown in my previous post. The first is an afternoon view at 2:49 pm, August 7th, today; the second is a sunset view at 8:05 pm, August 7th, today. The images use Google Earth's sun tool. Both images are looking to the northwest. As far as I know, there are no active ski lifts on this mountain.
As for the fairly recent eruption of the above unkown mountain - the Long Valley caldera has had earthquake activity and probable magmatic activity at depth in the last three decades, and erupted in a huge way about 760,000 years ago, sending ash half way across the U.S.
Our above mystery mountain erupted considerably more recently and sent ash a little more than half way across Nevada.
