Branching off Brinkerhoff Spring, 123 is a longer spur leading to a very random dead end with little room to turn around. The draw for this spur is the hiking offered that leads to the nearby plateau, with incredible views of the surrounding valley and cliffs. Obstacles along the trail include washouts and loose, chunky rocks that should pose no threat to stock, high-clearance 4WD vehicles. Camping is limited along this route and is all in the form of dispersed sites.
