Not illustrated. 1909 Excerpt: ... BLACKINTON'S RANCH. There is an exposure of the Yeso formation consisting of gypsum, gypsiferous shale, and earthy limestone near Charles F. Blackinton's ranch, 18 miles east of Socorro (locality 6, PI. I). From a limestone near the top of the gypsum the following fossils were obtained: Edmondia gibbosa?, Schizodus wheeleri?, Pleurophorus aff. subcostatus, and Temnocheilus aff. winslowi. A limestone, 50 feet or more in thickness, lying stratigraphically above the gypsum is presumably the San Andreas limestone. The rocks are not well exposed at this place, and it was not determined whether the space between the gypsum and the limestone is occupied by the light-colored sandstone which underlies the San Andreas limestone in well-exposed sections. No fossils were found in the limestone, but stratigraphically above it there are beds of red sandstone and shale unlike any observed below the undoubted San Andreas limestone. Lying unconformably upon these upper red sediments is a coarse-grained light-brown sandstone, about 15 feet thick, that constitutes the base of the Cretaceous and grades upward into shale and limestone containing fossils of Benton age. No fossils were found in these upper red beds, and their relation to the underlying limestone was not determined. It remains an open question whether they belong to the Manzano group or are younger. CARTHAGE. The next section in order southward (fig. 4) was measured a few miles north of Carthage, about 120 miles south of Galisteo Canyon (locality 7, PI. I). The lower part of the section is not well exposed and the estimated thickness of 300 feet for the Abo sandstone and 610 feet for the Yeso formation made in the field is probably too small, as these beds are known to be thicker both north and south of this plac...
