Mountains from overlook 3 miles north of Grand View Point. White Rim
Sandstone here is thicker than near Dead Horse Point (fig. 15) but
thinner than in Monument Basin and Stillwater Canyon (fig. 21, fig.
23). (Fig. 20)]
Let us now take the branch south of the Y and follow the narrow crest of
Grand View Point for about 6 miles to the main overlook. About 0.9 mile
south of the Y, a short walk to the west over the lower part of the
Navajo Sandstone affords a magnificent view of Stillwater Canyon of the
Green River, including Turks Head (fig. 23, fig. 24). Half way to the
point is a parking area and overlook, from which we get a spectacular
view of canyons cutting the White Rim and of the La Sal Mountains beyond
(fig. 20). Note that the White Rim Sandstone, which forms the broad
bench appropriately named the White Rim, is here much thicker than where
seen near Dead Horse Point (fig. 15).

Overlook on left skyline, Abajo Mountains on right skyline. Red
spires and cliffs in basin are Organ Rock Tongue of Cutler
Formation. (Fig. 21)]
Three more miles southward takes us to Grand View Point and its nearby
picnic area. Though named after the former Grand River some 2,000 feet
below, Grand View Point has a double meaning, for we see from here a
truly grand view (fig. 21)! At our feet is spectacular Monument Basin,
cut below the White Rim into the brick-red Organ Rock Tongue of the
Cutler Formation. The White Rim Sandstone here is slightly thicker than
to the northeast (fig. 20) but thinner than to the west (fig. 23),
because it forms a wedge-shaped body that thickens westward. In the
distance southeastward are the Abajo Mountains, just west of Monticello,
Utah. The prominent projection on Hatch Point on the left skyline is
Needles Overlook, from which the photograph in figure 27 was taken. A
closeup view of Monument Basin, showing Junction Butte and Grand View
Point in the background, is shown in figure 22. The slender spire in the
foreground has a measured height of 305 feet (Findley, 1971, p. 78).
