So using the TPC H-22B Chart and the knowledge gathered in a decade of exploration of the backcountry of Sonora and Chihuahua, we now present the following:

DPS GUIDE TO THE SIERRA MADRE OCCIDENTAL

Beginning at the north and working south from the border, we find Peak 8317, the summit of the outlier. Sierra de San Luis, located five miles south of the border and 37 air miles east of the Douglas-Agua Prieta border crossing. A new highway, Mex 2, only partially finished, runs from Agua Prieta to Janos, Chihuahua. Parts are paved, most of the rest is rough graded, but being held up pending construction of large bridges. Daily busses now run over it, and we crossed on it in October, 1980. We found only one tough grade but met a bus here, so any good DPS rig should have no trouble. Can't be sure where the road crosses the ridge, but would guess the takeoff point will be three miles west at 5250±. A poor but passible road runs SSE from Agua Prieta to Bavispe (SRL p.16), a distance of 100 miles and about six hours. Passing Col. Morelos at 72 miles, it enters a deep canyon located between Sierra San Luis and Sierra del Tigre, which lies to the west. In El Tigre we find peaks 8084 and 8028. A jeep road from Esqueda (SRL p.25) runs east passing the Angostura Lake Resort and then crossing the sierra at 5500±, but less than two miles from Pk 8048. On the east side of the canyon we find two other peaks, 8097 and 8245. To reach these, stop three miles short of Bavispe at San Miguelito and turn left up a well-graded road heading for Janos [NO ROAD SIGNS, ASK!]. This road used to carry a lot of truck traffic, but with the new Mex 2 extension, most of it is now diverted to it. We made it in 1972 in a Toyota pickup and only got stuck once in the 59 mile stretch between San Miguelito and Janos, after a bad storm that had closed the "road" for three days. Anyway, 12 miles up the road, it crosses the Sierra Madre Occidental at Carretas Puerto (6000+). Peak 8245 lies only an airline mile NW. But now you are approaching PEAK 9088, which Bill Hauser is nominating for the DPS PEAK LIST. You have now driven some 600 miles to Agua Prieta over paved highways, then 112 miles to the range crossing over poor to bad dirt roads, so it looks like this will be an expedition greater than any present Desert Peak. Peak 9088 lies 12 miles SW along the summit ridge, and this is an airline distance. However the map shows a possible alternate. Drop east, entering Chihuahua for a couple of miles to Hacienda Carretas (this name is subject to change with owners). From this ranch, plainly visible from the °road", a logging or mine road swings up a side canyon, then forks left heading for an elevation of 8000+, only a mile from the summit. The trouble is that these logging roads may or may not be passable, but it looks like a reasonable route, and even if only half of the road is open, it would save a long, though probably pleasant climb through open pine timber. Ten miles to the south lies 8176, but this can be reached by another logging road, running SE from Bavispe, which likewise passes within a mile of the summit. Several years ago, a friend, Merrill Miller, with a jeeping group from Texas, attempted to cross the range to Chihuahua in this area in April but were blocked near the summit by a late snowfall. A cluster of peaks surround the little village of Huachinera, which lies 26 miles south of Bavispe, or may be directly reached
