The 1930s and 1940s saw the introduction of a more profitable trade on the Colorado--river running and tourism. Norman Nevills, for example, headquartered at Mexican Hat and turned the red waters of the San Juan and Colorado into green cash as recreation became increasingly important. Even with the introduction of the Glen Canyon Dam in the 1950s and Lake Powell in the 1960s, there was still plenty of white water and red rock for adventurous souls to find the isolation and excitement they desired. And later, when its tributaries were heavily committed to irrigation and culinary use, the Colorado remained a playground for kayakers, rafters, and tourists. Today, the Utah portion of the Colorado River continues to offer not only its water as a resource, but also its beauty and adventure to those who come to its banks.
