Desert Rain
This is a dry lake bed in a desert. It hardly ever rains here.
But when it does rain, this dry lake bed fills with water. After a week of rain, the dry lake bed becomes a lake.
Wildflowers spring up around the lake. Their seeds have been in the ground, waiting for rain.
Rivers run into the lake. Fish swim into the lake from the rivers.
Pelicans come to the lake, happy to find fish to eat.
