Outer Limits is an extension to Alien Run
. It has a very different character, with sections of rocky climbing, steeper downhill sections, and meandering through dune-like terrain.
From the midpoint of the Alien Run
10 mile loop, head east and up a hill. The trail surface is coarse gravel and the grade considerable.
Once over the hilltop, the trail descends. There are no switchbacks on the downhill side...
The trail meanders north, skirting the edge of John Brown Canyon along high cliffs.
Beyond the canyon, the trail joins a road for about 700 feet. At the top of the hill, bear left and back onto the trail. Signage is pretty good. Watch out for fast-moving vehicles.
Now the trail turns back south, contouring along the base of a low escarpment. After a number of road crossings, the trail rejoins itself and closes the loop.
