...H. E. WRIGHT, JR.; ANNE M. BENT; BARBARA SPROSS HANSEN; L. J. MAHER, JR. Abstract The Chuska Mountains, with an elevation of 2,700 m above sea level, are covered with a forest of ponderosa pine punctuated by openings around small lakes. Spruce, fir, Douglas-fir, and aspen are found on the north...

... from the five species can be discriminated by a combination of eight qualitative characters and three dimensions. The same criteria were applied subjectively to the pine pollen in 20 stratigraphic samples from Dead Man Lake in the Chuska Mountains of New Mexico. Pinus edulis and P. ponderosa , the only...

...H. E WRIGHT, JR. Abstract The hundreds of small depressions in the flat crest of the Chuska Mountains of New Mexico are formed in cross-bedded siliceous Tertiary sandstone. The basins are bounded by low rock bluffs and contain intermittent lakes of irregular form and shallow depth. Many...

...ANNE M BENT; H. E WRIGHT, JR. Abstract Pollen analyses of 40 samples of duff and other surface materials from the major forest associations in the Chuska Mountains, New Mexico, show that a reasonably close correspondence exists between modern pollen rain and vegetation. This provides the basis...

...CONRAD R APPLEDORN; H. E WRIGHT, JR. Abstract The Chuska Mountains, in northwestern New Mexico and adjacent Arizona, consist of flat-lying Miocene (?) sedimentary rocks locally overlain by pyroclastic and flow rocks of the Pliocene Navajo-Hopi volcanic province. The volcanic rocks were extruded...

...James David Lowell Abstract Ancient stream directions in the lower Morrison formation of the Chuska Mountains, Arizona, may be reconstructed through use of cross-stratification mapping techniques. Dip directions of the cross-strata, when combined in the forms of histograms and vector resultants...

... to the Mesaverde group. Beds probably assignable to the Deza formation are exposed on the east flank of the Chuska Mountains about 12 miles north of Deza Bluffs, where there are at least 180 feet of white to buff, horizontally bedded sands with thin layers of light green or red shale and thin pebble beds near...

...Figure 2. (A) Digital elevation model for the Chuska Mountains area. Flat top of the southern Chuska Mountains is defined by silica-cemented zones within the Chuska Sandstone that formed during early, phreatic diagenesis (see text). Note the eastern boundary structure of the Laramide Defiance...

...H. E WRIGHT, JR. Abstract The Chuska sandstone as here restricted forms the cap rock of the Chuska Mountains, which extend 60 miles along the Arizona-New Mexico State line north of Gallup, New Mexico. Its maximum preserved thickness is about 1750 feet. It is unfossiliferous, cross-bedded throughout...
