Turning north from the intersection 7 miles east of Needles Overlook, we
traverse a nearly flat grassy tableland to Hatch Point Campground. In
figure 1 the campground is shown west of the old road; the new road is
west of the campground, but no map of the new route was available for
plotting in figure 1. About a mile before we reach the campground a jeep
trail heads west then northwest about 5½ miles to Canyonlands Overlook,
a scant mile from, but some 1,400 feet above, the eastern border of
Canyonlands National Park. This overlook affords fine views of the
Colorado River canyons and the eastern shore of Island in the Sky, but
at present (1973) there are no plans to improve the trail for
passenger-car travel.
Two miles north of the campground we cross a minor drainage leading
northeastward into the north fork of Trough Springs Canyon. The B.L.M.
plans a road down this canyon to Kane Springs Canyon, 1,100 feet below,
where it will connect both with a scenic drive to Moab, the lower part
of which is paved, and with the jeep trail going west over Hurrah Pass
(fig. 30) and thence south along the eastern benches of the canyons of
the Colorado River to the Needles district of the park. E. Neal Hinrichs
(U.S. Geol. Survey, oral commun. Feb. 16, 1973) reported specimens of
blue celestite (strontium sulfate, SrSO₄) and barite (barium sulfate,
BaSO₄) in the Cutler Formation at a point where a sharp bend of this
jeep trail crosses a fault, or fracture (fig. 56), in the northeast fork
of Lockhart Canyon (shown in fig. 1 as the easternmost loop of the trail
about 6 miles northeast of Lockhart Basin). Farther south, the trail
swings west of Lockhart Basin, whose center exposes part of a syncline
(fig. 28).
