Delicate Arch Area

Two and a half miles northeast of the road intersection near Balanced

Rock, a gravelled side road leads northeastward to several points of

considerable interest. The photograph in figure 11 was taken from this

side road about half a mile northeast of the intersection. About 2 miles

to the northeast, just beyond Salt Valley Wash, is a parking area (stop

17) at the beginning of the trail past Wolfe’s Bar-DX Ranch (fig. 3) to

famed Delicate Arch, which is featured on the front cover. Although the

trail to the arch is only 1½ miles long, it crosses several hills at the

outset, then climbs 500 feet, mostly on bare Entrada Sandstone, so is

considered quite strenuous, particularly in hot weather. The Park

Service advises hikers to carry water. The Walt Disney crew, cameras,

gear, cougars, and all climbed this trail in the hottest part of the

summer of 1971 (see p. 16), while my wife and I were working in the

vicinity. Visitors who do not wish to make the hike may get a distant

view of Delicate Arch by driving to a parking area (stop 18) 1.3 miles

farther east.

part of which is visible on left. Small opening on right is visible

also in figure 38. Largest arch is 39 feet wide and 64 feet high;

smaller one is 12 feet wide and 13 feet high. A still smaller one,

not visible in the photograph, is 8 feet wide and only 4½ feet high.

After leaving Wolfe’s Ranch, the trail to Delicate Arch crosses Salt

Wash on a suspension foot bridge (fig. 42). Just beyond the bridge, a

short walk to the left (north) leads to the Ute petroglyphs shown in the

lower photograph of figure 2. The most difficult part of the trail, on

bare sandstone, is marked by cairns of stones placed at sufficient

intervals to keep hikers from losing the barely visible trail. When the

summit finally is reached and the last corner rounded, one suddenly sees

perhaps the most sublime view in the park—famed Delicate Arch, framing

part of the La Sal Mountains beyond (fig. 43). This graceful arch and

mighty Landscape Arch (fig. 53) were considered to be in serious

jeopardy during the era of sonic booms, but hopefully this danger now is

past. (See p. 16-17.)

It may be of interest to shutterbugs that professional photographer Hal

Rumel lugged an 8- × 10-inch camera plus a heavy tripod and accessories

up the steep trail to get the excellent photograph of Delicate Arch

shown in figure 43. The late afternoon sun intensified the red somewhat,

but my shots made earlier in the day using both 4- × 5-inch and 35-mm

equipment resulted in unwanted shadows, even though the salmon color of

the Slick Rock Member was more nearly normal.

After leaving the junction with the side road, the main park road

traverses slices of vertical strata squeezed between faults along the

north side of Salt Valley, then gradually climbs out of the valley for

about 2 miles to a parking area (stop 19), from which good views are had

of the southeast end of Salt Valley and of the grabens in the west end

of Cache Valley. (See fig. 11.)

Wolfe’s Ranch. The opening is 33 feet wide and 45 feet high. The

left abutment is only 5 feet wide at the narrowest point. The arch

is carved near the top of the Slick Rock Member, and the top of the

span, 19 feet thick, is capped by a few feet of the more resistant

Moab Member, as is Broken Arch (fig. 16). Photograph by Hal Rumel,

Salt Lake City. (Fig. 43)]
