As she swam, Margarita explained that the Rio Grande is formed by the joining of several streams in the San Juan Mountains of Colorado, just east of the Continental Divide. From there, it flows through the San Luis Valley, then south into the Middle Rio Grande Valley in New Mexico, passing through the Rio Grande Gorge near Taos. The river then continues south through the desert cities of Albuquerque, and Las Cruces to El Paso, Texas and Ciudad Juárez, Chihuahua. The Rio Grande ends in a small, sandy delta at the Gulf of Mexico. Along the way, the river forms part of the Mexico-United States border. Its total length is almost 2000 miles. Needless to say, the chicks often grew restless and Mama Chicken would swim alongside Margarita to allow the chicks to burn off some energy.
Once they reached Colorado and The Rockies, Ms. Chick was astounded by the red rock formations and the height of the mountains. Margarita explained that, hundreds of years ago, the mountains were once entirely covered by oceans. She described many of the fossils that had been found proving this and also told them that dinosaurs had once roamed there as well. She even stopped to show them many of the dinosaur tracks embedded in the rocks.
Before heading off to the next artist in Canada; the little troupe decided to have one more trip to the warm sunny beaches of Cancun. While the trip into the Rockies had taken quite awhile (Margarita had been swimming upstream) the return trip went quickly since they simply shot the white water rapids back. Lying on the beach later that day, they all toasted their adventure with a pitcher of margaritas (their friend’s namesake) and agreed that perhaps they should venture below the equator someday.
