Pg. 93. Gobbler formation of Magdalena group. Appears only on composite columnar section, Sacramento Mountains, Otero County, southeastern New Mexico. Consists of limestone, sandstone, and shale. Coarse quartz sandstone in lower part. Includes massive gray cherty Bug Scuffle limestone member which grades laterally into sandstone and shale. Thickness as much as 1,600 feet. Underlies newly named Beeman formation and overlies Helms formation. Age is Early(?) to Late Pennsylvanian (Morrowan? to Missourian).

Pg. 73 (fig. 20), 75-84, pls. (geol. maps). Gobbler formation of Magdalena group. Basal 200 to 500 feet consists of well-sorted quartz sandstone and limestone with black chert masses; contains Tertiary(?) intrusive sills. Upper 1,000+/- feet consists of contemporaneous, interfingering facies, the Bug Scuffle limestone member and unnamed detrital facies of shales and quartz sandstones. Total thickness 1,200 to 1,600 feet; 1,287 feet at type section. Underlies Beeman formation. Unconformably overlies Rancheria formation; deposited on a subaerial erosion surface, which in northern part of area was channeled locally to a depth of about 100 feet. Fossils. Age is Early(?) to Late Pennsylvanian (Morrowan? to middle Missourian).
