Because of extra rain and snow received in the Northern Chihuahua Desert during the winter, the desert wildflower climax this spring is said by some to be a 100 year event. These photos were taken as we entered Big Bend NP from Marathon with the Chisos Mountains in the background; then on the Cattail Falls Trail below the Window, and finally along the River Road from Lajitas to Presidio.
