Mid-Tertiary and Pleistocene sections, Sotol Vista to Cerro Castellan, Big Bend National Park, southwestern Brewster County, Trans-Pecos Texas
Authors: Stevens James B. 
Published: November 2007

Abstract
Texas 118 becomes the main park road at the western entrance to Big Bend National Park, in southwestern Brewster County, Trans-Pecos Texas. The traverse lies along Ross Maxwell Appreciation Scenic Drive, which turns off the main park road 9.4 mi (15.1 km) east of this entrance, and provides principal access to the southwestern part of the park. The traverse begins at Sotol Vista (Fig. 1), a 0.3 mi (0.5 km) loop off the drive 8.5 mi (13.7 km) from the turn, and ends at the eastern base of Cerro Castellan 9.4 mi (15.1 km) to the southwest.
The traverse provides examples of the stratigraphy (Figs. 2,3) and structure on which many conclusions about the eastern part of an intraplate boundary are based. This traverse lies entirely within a national park; without the proper permits it is illegal to collect rocks, fossils, plants, or animals, and unwise to carry a rock hammer. Collecting permits should be arranged well in advance with the Resource Management Office, Big Bend National Park. It is also important to remember that this is desert country. There is no reliable supply of potable water along Ross Maxwell Appreciation Drive.
Late Quaternary geology of the Texas coastal plain
Authors: Morton Robert A. 
Published: November 2007

Abstract
Modem depositional environments prominently displayed along the northwestern Gulf of Mexico served as the first widely accepted sedimentary facies models that have successfully guided exploration and production of a variety of energy and nonfuel resources (petroleum, lignite, uranium, geothermal energy, construction aggregate, ground water). Because these industrial activities both required and provided a tremendous data base, the depositional environments of the gulf coast are among the best known anywhere. The following sections of the guidebook describe selected geological features that typify late Pleistocene and Holocene sediments of the Texas coastal plain and illustrate the diversity of associated depositional environments. The described sites represent a spectrum of transgressive and regressive sequences coexisting along a microtidal storm-dominated coast undergoing a significant reduction in sediment supply and a slight sea-level rise. Late Quarternary history. The Texas coastal plain is a broad, flat, depositional surface created by several rivers that eroded large volumes of sediment from remote areas of the state and adjacent mountainous regions and deposited the sediment as coalescing deltas in the Gulf of Mexico (Barton, 1930, Doering, 1935; Winker, 1979). It extends eastward and merges with the coastal plain of Louisiana, which has a similar morphology but a slightly different origin. Rather than being formed by several rivers and deltas of moderate size as was the Texas coast, the Louisiana coastal plain was mostly deposited by two large alluvial systems (Mississippi and Red rivers) that drained much of the continental interior.

Carlton rhyolite and lower Paleozoic sedimentary rocks at Bally Mountain in the Slick Hills of southwestern Oklahoma
Authors: Donovan R.N. , Ragland D. , Cloyd K. , Bridges S. , Denisen R. E. 
Published: November 2007

Abstract
The Bally Mountain Range is located in eastern Kiowa County in southwestern Oklahoma (T.6N., R.14W.). The closest important road is Oklahoma 58 (Fig. 1). This road can be accessed from the H. E. Bailey Turnpike by taking the Medicine Park exit a few miles north of Lawton. Alternatively, the route can be joined from the north by taking the Hydro exit from 1-40. The easiest way of reaching the site is to proceed north on Oklahoma 58 for 3 mi (4.8 km) from its junction with Oklahoma 19, then turn west along a partly paved county road for 3 mi (4.8 km). Just before reaching the most prominent hill in view (which is Bally Mountain), turn right on an unpaved road and proceed north for a few hundred yards to the only inhabited house (on the west side of the road). This is the home of Mr. W. Hodges, the principal landowner in the area, where permission to visit the site should be sought. In common with several other landowners in the area, Mr. Hodges freely allows large parties of students access to his land on condition that they do not smoke or leave litter and that they close all gates, etc. His house is very conveniently situated; immediately to the west is the bulk of Bally Mountain, which is composed of Carlton Rhyolite. This hill is 1,900 ft (580 m) high and rises 350 ft (107 m) above the surrounding plains. To the north and east rises the remainder

Geology of Lookout Mountain, Georgia
Authors: Cramer Howard Ross 
Published: November 2007

Abstract
Lookout Mountain is in Dade and Walker Counties, Georgia, in a relatively rural part of the state. However, it is near interstate access roads and lends itself well to field trips.
