Another 2½ miles around the south rim of Red Canyon and the head of Columbus Canyon takes us to the junction with the paved county road known as the DS Road, which leads south and southwest to Glade Park and to the head of No Thoroughfare Canyon. This important intersection will be included in trips through Glade Park and around the head of No Thoroughfare Canyon, so it will be discussed later. Meanwhile, we will continue our trip eastward from this intersection. About a third of a mile to the northeast is a large parking area, with a path leading to a fenced overlook at the rim of Columbus Canyon for viewing Cold Shivers Point—perhaps the most aptly titled feature in the Monument (fig. 53). A primitive path leads from the overlook to the toadstool-shaped platform at upper right, on which some visitors dare to stand, but not me. When the old, steep Serpents Trail was the only route for autos to ascend from the East Entrance, barrels of water were kept at this parking area to quench the thirst of boiling radiators. HEAD OF SERPENTS TRAIL [Mile-marker 31] After leaving the parking area, the downgrade on the Kayenta Formation begins to steepen to the northeast until it becomes advisable to shift into second gear. In about half a mile we descend a series of steep switchbacks cut into the Wingate Sandstone on the steepening Ladder Creek monocline (figs. 8, 29), and we reach the present upper end of the old Serpents Trail (fig. 54), which is now an interesting foot trail. As noted earlier, it is convenient to hike down this steep 2½-mile trail and to have one member of the party drive ahead and await the hikers at the parking area in the Devils Kitchen Picnic Area, near the foot of the trail. One of many rewarding views seen during the hike is shown in figure 55, another was seen in figure 10.
