I have a book on clouds and cloud formations I bought at the Apgar Visitor Center some time back....'cause I like weather related stuff. I like being my own weatherman It's helpful for when you're out in the boonies to be able to be able to know what sort of weather may be coming your way.
This is a page that gives some insight on "lenticular" clouds. Pretty good layman's explanation on how and why they form. Kind of interesting if your into clouds and weather.
