TRACHT, J. 1992 Journal Big Bend Ranch State Natural Area 20 miles E of Presidio Presidio Co Texas May 22-27 no vegetation of any height certainly nothing to even partly caused a mist (court) nor. At the top is a small cottonwood (8" dbh, 30') and to the E there is a small blackberry (about 10'), but the rest is sparse stature throuscant and bare rock! I'm not at all sure why Kelly recommended it. Lae Cuema Big Bend Ranch State Park site Presidio County Texas Elev. 3600 ft. Lae Cuema is a riparian area along Bojaciles Creek in the lower (3 miles) desert canyon that is Bojaciles Canyon. The canyon is bounded by near-verti- cal basaltic outcrops. Three to N are 300-400 ft higher than the creek bend, three to S are 700-900 ft higher, and go no further W. Within these points is an outcrop of layered rock, looking like rock eductures as "welded tuff" in Big Bend National Park. There are numerous buried shallow caves in this formation, hence the name of the place. The creek has divided the tuff into N. & S. portions, and the tuff is the visible bedrock in the creek. The N. portion is approx: 80' deep, S. portion 45'. This is a significant archeological site, too. Lae Cuema is 6.0 miles from Cuesta Zarca. Lae Cuema has three fairly distinct riparian areas, separated by desert-types growth right to the banks of the creek. Farthest upstream is a 50 yd-length of creek drained by Salix sp., about 25 trees to 35-40' highest growing right along the creek, mostly on the south bank. The willows are cleared forkended by two 50' cottonwoods. Six feet from the creek 20' or the S. bank is a large willow - 20" dbh & 45' tall. The S. & W. sides of the tree to a height of 30' are covered w/ grape. This is just 40' downstream from a medium-sized Fremont Cottonwood (14" dbh, 40' tall). Below is a thin understory of soapwillow and certain feather-barkiny pears I don't know, plus some 2' grasses. The floodplain widens on the S. bank below this big willow, and is thickly grown with certain plants I don't know - it looks like soap- willow spikes 5'-9' tall. Some of this is overgrown by grape and other quit.
