Hamburger Rocks

If you begin your trip by hiking south from the Post parking area along the Halls Creek drainage, it is easy to miss the route into Lower Muley Twist Canyon. Track your location on a topographic map and scan the steep slickrock slopes of the Fold for the upper portion of the north-facing wall of Lower Muley Twist Canyon. The wall is stained with desert varnish and is visible a good distance away. Stay in the Halls Creek drainage until you encounter the entrance to Lower Muley Twist Canyon further downstream. Follow Lower Muley Twist Canyon north until you reach the Post Cutoff Trail or continue up canyon to the trailhead on the Burr Trail Road, depending on your destination. From the confluence of Lower Muley Twist Canyon and the Halls Creek drainage, hike south on the remnants of an old road for about 0.7 mile (1.1 km) to a sign marking the spur route to Muley Tanks, which are on the right (west) and above the wash at the base of the Fold. (Hamburger Rocks are located low on the Fold about 200 yards (183 m) south of this point.) Continue south on the main route another 0.2 mile (0.4 km) past the Muley Tanks sign to a sandy wash crossing. Turn right (west) and eventually climb a broad slope of white Navajo sandstone until the dark-red Hamburger Rocks come into view (about 1/4 mile [0.4 km] above the main route). Return via the same route. From The Post parking area, you can hike directly to Hamburger Rocks by following the Halls Creek drainage to the south. You will pass the narrow cut into Lower Muley Twist Canyon after 4.7 miles (7.6 km). Hamburger Rocks are approximately one mile (1.6 km) beyond this point. Follow the directions in the previous paragraph. Round-trip distance for the side trip from the Lower Muley loop route to Hamburger Rocks is 2.3 miles (3.6 km). Total round-trip distance from The Post parking area to Hamburger Rocks via Halls Creek is just over 11 miles.
