Just before we reach the T-intersection with the eastern segment of
South Broadway we may still see on the right some of the destruction
caused by a devastating flood that roared down No Thoroughfare and other
canyons on September 7, 1978, as a result of what was termed the worst
cloudburst to hit Glade Park, the Monument, and the Grand Valley since
1958. A house on the flood plain just above the bridge was badly damaged
and was filled with 4 feet of mud, and the Monument Road bridge across
No Thoroughfare Canyon nearest the intersection was washed out,
necessitating the rerouting of traffic to and from the East Entrance of
the Monument. Moral—never build a house or even pitch a tent in a dry
wash or arroyo in desert regions! Incidentally, indirect measurements by
engineers of the U.S. Geological Survey indicated a discharge of 9,290
cfs just above the washed out bridge in No Thoroughfare Canyon, and
2,980 cfs in Red Canyon beneath the Broadway bridge.
SOUTH BROADWAY
Inasmuch as the bridge on Monument Road has long since been rebuilt, we
will cross it, turn right on South Broadway at the T-intersection, cross
the Redlands Power Canal (p. 88), and join Colorado Highway 340 at the
traffic light; thus, we complete a round trip “From Grand Junction
through The Redlands to the West Entrance of the Monument,” “Through the
Monument from West to East Entrances,” and “From the East Entrance to
Grand Junction.”
Through Glade Park from the Northwest Arm of Ute Canyon to Columbus
Canyon
GLADE PARK ROAD
[Mile-marker 34]
A very pleasant 11-mile drive through Glade Park may be made from the
intersection where Rim Rock Drive crosses the northwest arm of Ute
Canyon (p. 108) to the intersection with the same drive on the rim of
Columbus Canyon a quarter of a mile southwest of Cold Shivers Point (p.
120). The name Glade Park refers not only to the Store and Post Office
mentioned earlier, but also to a nearly flat farming and ranching area
south of the Monument—an area entirely different from the Monument or
The Redlands. Most of the cultivated part of Glade Park is underlain by
nearly flat lying Entrada Sandstone which was weathered to a sandy soil,
but a few areas are underlain by the Morrison Formation. This drive
should appeal particularly to people spending from a few days to a week
or more in the campground. For the more adventuresome, other interesting
roads join Glade Park from several directions, as noted below.
After leaving Rim Rock Drive at Ute Canyon, on a good gravelled road, we
traverse attractive, hilly, wooded country generally southward for about
a mile and climb some 300 feet to a flat area covered mainly by
sagebrush and grass. About 3 miles south of the intersection, we see on
the left the leached white outcrops of the Entrada Sandstone shown in
figure 19.
