Sat. 7/19, 9am: The Rio Grande is the heart of New Mexico. We'll learn how the river looked in the past, what it's doing now, and what we can expect for the future. The Rio Grande stretches a magical 2,401 miles, from its source in Colorado, all the way to the far southern border of the United States. Joining us is Jennifer Scheutz from the Bosque Ecosystem Monitoring Project. Plus, the cast of James and the Giant Peach will roll through the studio.
