Wildlife management Southwestern States Congresses; Wildlife management Mexico Congresses. I Figure 3.—Pinyon-juniper-oak woodland occurs above the desert grasslands to about 6,500' elevation. The round rosettes of leaves are Agave totrerana. on drier south slopes up to 7,000 feet. But some- where around 6,500 feet elevation a more extensive forest begins that runs to the very tops of the highest pinnacles. The real treasures of the Maderas del Carmens occur in the highlands. There is where the forest crowns the rhyolitlc castles and hides the fragile neadows and grassy streams. Southwestern White and Ponderosa Pines blend with an amazing variety of oaks on open flats and ridges, and Douglas-fir and Arizona Cypress are more common in drainages and other pro- tected niches. Coahuila Fir grows in some of the moist out of the way canyons (Muller, 1947). The rocky crags and canyons are the real attra- tions that entice the wilderness lovers initially. The southern series of peaks run on almost an exact north-south line for about eight miles. Loomis Peak (8,960') and Peregrine Point (approximately 8,500') are the highest of the series. Although the west face is a sheer cliff for a thousand or so feet, followed by a series of talus slopes and rocky ridges, a high bench drops off suddenly onto Canon del Oso that runs south for almost the total length of the southern peaks. North of the southern five peaks is another series of peaks and deep canyons (Figure A) that are just as extensive in length. The northernmost peak dominates the entire northern area. This is Pico Centinela, the highest peak in the del Carmens, that rises to 11,975 feet above sea level. It con- sists of steep, rocky slopes and sheer precipices. There are no forested benches on Centinela as there are on the southern peaks, but a few patches of Quaking Aspens
