1985 Map of Big Triangle

About this map

The Colorado River snakes through the canyonlands of Grand County, Utah, defining a landscape of deep washes and high plateaus. At Cisco Landing, the waterway provides a rare access point before plunging into a series of whitewater challenges including Skull Rapids, Sock-It-To-Me Rapids, and Last Chance Rapids. These named features, alongside Funnel Falls, illustrate the river's character as it transitions through the Westwater Canyon area.
