The perfect blend of Mother Nature and restrained engineering on one of Moab's hardest trails.

Features -none-


Rockstacker was created with an elegant touch that used trail engineering to enable a spectacular and unlikely line, rather than to dumb down the terrain.

Some of Moab's trickiest and most intimidating rideable features are found in this short stretch of trail, including unbrakeably steep, sandy slabs; narrow, tall, scary drops; and technical, tight switchbacks through boulder gardens. Some of this is sited above serious consequences.

Begin by riding up the Amasa Back trail to the saddle just past the water pipe across the road. At the end of Rockstacker, you can ride up to rejoin this point and descend the way you came, or exit via Captain Ahab.

Continue out to the Amasa Back on two-track narrowing to singletrack. You'll have a low bluff on your right. As it comes to an end just before you get to the golden Navajo sandstone slickrock area that holds Pothole Arch, watch for a right spur.

This is the start of the Rockstacker trail. If you take the right turn and don't immediately run into a narrow, 5-foot, white sandstone mandatory drop next to a cliff wall, then you're in the wrong place. This feature will feel wildly out of character with just about everything you've seen so far.

Walk, ride and stare slack-jawed at the trail. At the end, you reach a junction where the choice is either down the sketchy, demanding, exposed Jackson singletrack, or up to rejoin the saddle from whence you came. Either way is a giggle-fest. Do them both!
