THREE FOURTHS OF A MILE beyond the checking station, South Camp Road turns left and joins South Broadway 2-1/2 miles to the northwest. This provides a fine shortcut for persons desirous of travelling back northwestward through The Redlands to regain the West Entrance of the Monument. The intersection of South Camp Road and South Broadway, a key point on the trip "From Grand Junction through The Redlands to the West Entrance of the Monument," is noted on page 89.

But let us continue our 3-mile return trip to Grand Junction, in order to point out several things of interest along Monument Road in the lower part of No Thoroughfare Canyon. As the canyon narrows just beyond the road intersection, we see on both sides colorful badlands of the Morrison Formation capped by the rusty looking basal sandstones of the Burro Canyon Formation. Behind the building on the right just before the road curves to the left is an artesian well 575 feet deep that taps both the Entrada Sandstone and a sandstone lens in the Morrison Formation³⁵.

About 2-1/2 miles below the checking station, we pass on the left the basal sandstone of the Burro Canyon Formation resting on the Morrison Formation, as shown in the lower left of figure 24. Just beyond we may look up the hill to the left and see the 40-foot basal conglomerate of the Dakota Sandstone resting unconformably on an old erosion surface atop the Burro Canyon Formation.

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! Incidently, 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.

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."
