Only a real nerd can truly appreciate this picture. It's an alluvial fan in Death Valley, but the different colors of each lobe represent a separate debris flow that brought material down off the mountain with the gray one being the most recent. That's what a geology course will do to a person.

Flowers in Death Valley. No, they aren't natural, they were growing in a flower pot outside a gas station. See how photographs can be made to look so much better than real life?

Sand dunes at Death Valley. I think I like the bottom picture best b/c of the angle.

Some badlands in Death Valley. I always thought the term badlands was just a generic term to describe a really harsh desert environment, but have now learned that it's a very specific geologic feature pertaining to very fine sediments that are constantly shifting so vegetation never gets a chance to take root. If I learned it you have to too.
