Located just north of Hwy 287. . . west of 220, and east of Lander (see: Jeffrey City).
Cranner is a rest-stop/historical area (with pit toilet).
Split Rock was an Oregon Trail and Mormon Trail landmark.
The Sweetwater River passes through here; enroute from the Wind River's. . . though not so glorious in this area.
If you do venture far from Cranner then also be aware of abundant POISON oak, ivy, snakes, tics bats bugs lizards canids felines bulls cows horses deer moose griz rodents birds ranchers named Bud aliens ghosts and ancient hosts (and all the ornery flying critters you can think of). . . .
The rock 'round here is excellent. . . NO! I mean, scabby, putrid, exfoliating granite. . . not nearly as good as the worst in Mojave.
One more . . . watch out for slung lead. The rednecks, redskins and Red Army in these parts prefer shooting to damn near anything - as do the miners and roughnecks, and some climbers maybe. If you're seen with out-of-state (esp. green) plates you'll be rounded up with the cattle, castrated and branded.
If somehow you slip by, don't take nothin', don't leave nothin', stick to the roads, and tread lightly. . . and leave all gates as found (open/close). (from mountain project)
