Where in the West - August: Another View or Two

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.
