Rain Gauge

The stalk height of Elegant Clarkia (Clarkia unguiculata) is a good indicator of seasonal rainfall.

One of the best indicators of seasonal rainfall I've found in the oak woodland and chaparral areas of Southern California in which I run is Elegant Clarkia (Clarkia unguiculata). In a wet year it can grow more than 6 ft. tall. This year it is the shortest I've ever observed -- about 5 inches in this photo taken near Lasky Mesa.
