Desert Vegetation

We have some crazy vegetation here in the southwestern U.S.
These are dry pods of a Yucca plant and I don't know much about them; only that their roots were once used for soap by the indians.

Remember the blip of the weed I took a few days ago? It turns out it's a species of tumbleweed; I only notice them when they get large, dry, and see them rolling across the road. It's so annoying when they get stuck in front of your car while you're driving. I do start giggling when I see it happen to someone else though. Hope to blip that one day.
