Ok Les, how about a bit more info on where you were flying? Some of the horizontal lines on those hills look very much like water lines.
Things have turned green early this year in California. We do not usually really see green until March or April. Usually the new green stuff has to grow tall enough to rise above the old dead stuff from last year. But I guess we did not get much growth last year with the lack of rain. And once it finally turns green in the spring, then it turns brown by the end of May.
I can imagine some really interesting video if you catch it at the right time where the south facing slopes are brown and the north facing slopes are still green.
