U.S. Senator Mark Udall plans to introduce legislation later this summer that would create the Brown's Canyon National Monument. The monument would cover 22,000 acres between Salida and Buena Vista in Chaffee County and includes 10,500 acres of new wilderness. The proposal seeks to protect one of southern Colorado’s most coveted wild trout fisheries and surrounding outstanding backcountry hunting areas.
