I see that sight every time I go to work Bud. "If you're on the left-hand side you have a nice view of Mount Rainier." I was hiking up there with the wife and kids on Saturday, as a matter of fact.
I gotta' go to an SCR one of these days. Thanks to all of you who posted your photos! Someone needs to make a DVD for us unfortunates who didn't make it.
By the way, that's a cap cloud. The mountain causes the moist air mass to flow up and over the peak. The moist air cools as it rises and the water vapor condenses and forms that neat looking cloud.
