According to the Desert Wildflowers website, http://www.desertusa.com/wildflo/mnp.html:

Feb. 11, 2010 Death Valley park reports: This week’s
storms have brought more rain to Death Valley, which increases the
chances of a moderate wildflower bloom this spring.

Moderate wildflowers! Cooome on. It has been raining a lot in Southern California and I expected that this was going to be a great year for wildflowers in Death Valley. Like 1982. Or 2005 when even the roads had water in them.

The whole bottom of the valley was filled with water,

and there were flowers everywhere.
