Canyonlands National Park is divided by the Green and Colorado Rivers into three distinct districts. Needles, Island in the Sky, and the Maze. There are no roads connecting them because the rivers and some very deep ditches are in the way. Island in the Sky is about a two-hour drive north of the Needles. The Maze is another matter. It can be reached only via a very long and circuitous route.
Potholes aren't always holding water in Canyonlands National Park, but when they do, check out the reflections.
