Park at the Granddaddy Basin Trailhead (end of route 315), which is on the south side of the Uintas, and can be accessed from route 35>144>315. You'll want to use google maps to look for Grandaddy Basin Trailhead to find it. Start out of the trailhead on the main trail, ready to hike for a while. You'll loop around, and start doing switchbacks. Look for a climber's trail that cuts off the switchback up a rocky slope, and follow this faint trail for the bulk of the hiking until you come to a small lake. Walk around (either way, but the east side seems a bit easier), and you will see the boulders on the N/NW side.
