Fun Fact Friday: Oh, the mighty Colorado River! Its history is quite impressive as it broke through the Grand Canyon about 5 million years ago. Evidence also suggests that the Colorado River was flowing through the Rocky Mountains as they were still forming. This river has influenced much of the beautiful geology we see across the west today. All along the Colorado River system, anglers can find largemouth bass, rainbow trout, channel catfish, black crappie, walleye and striped bass. If you have not checked out the interview we did with Kirk Klancke, president of the Colorado River Headwaters TU Chapter, about restoring flows to one of the first main tributaries of the Colorado River, then be sure to check it out here.
