Fiery Furnace

About half a mile farther uphill is a parking area for viewing the

southeastern part of the Fiery Furnace (stop 20), a vast array of

towering fins and pinnacles of the reddish Slick Rock Member separated

by narrow slots, vaguely resembling flames shooting skyward. The view of

the Fiery Furnace in figure 44 was taken about 1 mile farther up the

hill. It is not difficult to get lost among this myriad of fins and

narrow slots, so ranger-guided tours are conducted during the summer.

About 1 mile farther northwest is a parking area (stop 23) from which a

short walk to the north end of Fiery Furnace leads to a narrow slot

between high fins (fig. 45), along which a short sandy trail leads to a

recess along the southwest wall containing Sand Dune Arch (fig. 46).

This hidden arch receives sunshine only near the middle of the day and

is a delightful, shady place to rest.

From the entrance to the slot leading to Sand Dune Arch, a trail goes

half a mile north across an open field to Broken Arch, shown in figure

16. This field, which separates the Fiery Furnace and Devils Garden

areas, is seen from the air in figure 12.

Slick Rock Member (fig. 12), but the top of the Dewey Bridge Member

is seen to the right of the curve in the road. (Fig. 44)]
