It was prepared as part of the Bureau of Land Management's Cultural Resource Manage- ment Program and is the second complete history of a BLM district in Colorado. A major objective of the Bureau of Land Management, Department of the Interior, is the identification, evaluation and protection of the nation's historic heritage and values, particularly those under the management of the Bureau. The history of Southwestern Colorado is designed to provide a baseline narrative for Cultural Resource Management. Paul M. O'Rourke has written a new history of the southwest corner of Colorado and in doing so, has provided a timely and original view of Colorado's heritage and history. This study will become part of the over-all history of Colorado as prepared by the Bureau and as other volumes dealing with Colorado history are written, they too will be made available to the general public. -

Structural Geology
2 STRUCTURAL GEOLOGY Conventional Map A map is a proportionate representation of an area/structure. The study of maps is known as cartography and the experts are known as cartographers. The maps were first prepared by people of Sumerian civilization by using clay lens. The characteristic elements of a map are scale (ratio of map distance to field distance and can be represented in three ways—statement method, e.g., 1 cm = 0.5 km, representative fraction method, e.g., 1:50,000 and graphical method in the form of a figure), direction, symbol and colour. On the basis of scale, maps are of two types: large-scale map (map gives more information pertaining to a smaller area, e.g., village map: 1:3956) and small: scale map (map gives less information pertaining to a larger area, e.g., world atlas: 1:100 km). Topographic Maps / Toposheet A toposheet is a map representing topography of an area. It is prepared by the Survey of India, Dehradun. Here, a three-dimensional feature is represented on a two-dimensional map and the information is mainly represented by contours. The contours/isohypses are lines connecting points of same elevation with respect to mean sea level (msl). The index contours are the contours representing 100’s/multiples of 100’s drawn with thick lines. The contour interval is usually 20 m. The contours never intersect each other and are not parallel. The characteristic elements of a toposheet are scale, colour, symbol and direction. The various layers which can be prepared from a toposheet are structural elements like fault and lineaments, cropping pattern, land use/land cover, groundwater abstruction structures, drainage density, drainage divide, elongation ratio, circularity ratio, drainage frequency, natural vegetation, rock types, landform units, infrastructural facilities, drainage and waterbodies, drainage number, drainage pattern, drainage length, relief/slope, stream order, sinuosity index and infiltration number. -

Selected Core from the Albert Formation (Mississippian), Moncton Basin, Southern New Brunswick
Selected Core from the Albert Formation (Mississippian), Moncton Basin, Southern New Brunswick Dave Keighley* University of New Brunswick, Fredericton, New Brunswick, Canada [email protected] and Clint St. Peter Hugh John Flemming Centre, Fredericton, New Brunswick, Canada Abstract Introduction The Moncton Basin is located in the southeastern part of New Brunswick (Fig. 1) and has a long history of petroleum activity. In the area ~25 km S of Moncton there has been mining of solid bitumen, Albertite, at Albert Mines (1850's); minor and intermittent production of oil/gas at Dover and Saint-Joseph (1859 to 1905); and oil and gas production at Stoney Creek (1911 to 1991 - gas was piped to the city for ~80 years). Stoney Creek gas is sweet, but wet, and the oil (total in place ~2.1 x 106 m3 with <5% recovered to date) is paraffinic with a pour point of over 7oC (45oF). Numerous appraisals of the oil shale in the area (e.g. Shell Albert Mines # 4 borehole) have also been undertaken periodically. In 2000, focus shifted 80 km west, where the McCully Gas Field (~1 TCF in place) was discovered, east of Sussex, by Corridor Resources Inc. and Potash Corporation of Saskatchewan (PCS). The A-67 discovery well (initial flow: 2.5 mcf p. day), and adjacent P-66 well currently produce gas for the PCS mill, but a link to the M&NE pipeline (Fig. 1) is planned to go into operation in late 2006. Approx. 17bcf (proven, ~120 bcf P2) remains in this production area (8% of the total joint venture area). -
Ecca Group) of South Africa: a Preliminary Review of Palaeoniscoid Fishes and Taphonomy
Records of the Western Australian Museum Supplement No. 57: 175-181 (1999). The Permian Whitehill Formation (Ecca Group) of South Africa: a preliminary review of palaeoniscoid fishes and taphonomy Fiona J. Evans 1 and Patrick A. Bender2 I Department of Zoology, University of Stellenbosch, Private Bag Xl, Matieland, 7602, South Africa; email: [email protected] 2 Museum of the Council for Geoscience, Private Bag Xl12, Pretoria, 0001, South Africa Abstract - The Permian (Artinskian) Whitehill Formation (Ecca Group) in South Africa and southern Namibia was deposited as part of a large stratified inland sea which extended from the southern margins of South Africa, and southern Namibia, northern Namibia (Aba-Huab Formation, Huab Basin) to the Iratl Formation of the Parana Basin in Brazil and parts of Uruguay. A common biota exists between these two continents, namely mesosaurid reptiles, pygocephalomorph crustacea, wood, palaeoniscoid fish and insects. The Whitehill Formation also contains plant stem fragments, palynomorphs, coprolites, a cephalochordate, rare sponge spicules and traces of arthropods and fish. The good preservation, particularly of the palaeoniscoid material, from the Whitehill Formation contrasts strongly with the disarticulated scales and spines from northern Namibia and Brazil. Recent collections in the Whitehill Formation near Calvinia and Louriesfontein (Northern Cape Province) of South Africa have demonstrated the necessity for a review of the palaeoniscoid taxa present in these units. Possible new species have also been collected, including a deep-bodied form. INTRODUCTION The extensive stratified inland sea in which the Whitehill Formation (Ecca Group, Karoo Supergroup; - - - - - Waterford Fm Figure 1) was deposited had limited or no access to ------------ the ocean according to reconstructions by Oelofsen Fort Brown Fm and Araujo (1987) and Pickford (1995). -

Observations on Normal-Fault Scarp Morphology and Fault System Evolution of the Bishop Tuff in the Volcanic Tableland, Owens Valley, California, U.S.A
Observations on normal-fault scarp morphology and fault system evolution of the Bishop Tuff in the Volcanic Tableland, Owens Valley, California, U.S.A. David A. Ferrill, Alan P. Morris, Ronald N. McGinnis, Kevin J. Smart, Morgan J Watson-Morris, and Sarah S. Wigginton DEPARTMENT OF EARTH, MATERIAL, AND PLANETARY SCIENCES, SOUTHWEST RESEARCH INSTITUTE®, 6220 CULEBRA ROAD, SAN ANTONIO, TEXAS 78238, USA ABSTRACT Mapping of normal faults cutting the Bishop Tuff in the Volcanic Tableland, northern Owens Valley, California, using side-looking airborne radar data, low-altitude aerial photographs, airborne light detection and ranging (LiDAR) data, and standard field mapping yields insights into fault scarp development, fault system evolution, and timing. Fault zones are characterized by multiple linked fault segments, tilting of the welded ignimbrite surface, dilation of polygonal cooling joints, and toppling of joint-bounded blocks. Maximum fault zone width is governed by (i) lateral spacing of cooperating fault segments and (ii) widths of fault tip monoclines. Large-displacement faults interact over larger rock volumes than small-displacement faults and generate larger relay ramps, which, when breached, form the widest portions of fault zones. Locally intense faulting within a breached relay ramp results from a combination of distributed east-west extension, and within- ramp bending and stretching to accommodate displacement gradients on bounding faults. One prominent fluvial channel is offset by both east- and west-dipping normal faults such that the channel is no longer in an active flowing configuration, indicating that channel incision began before development of significant fault-related geomorphic features. The channel thalweg is “hanging” with respect to modern (Q1) and previous (Q2) Owens River terraces, is incised through the pre-Tahoe age terrace level (Q4, 131–463 ka), and is at grade with the Tahoe age (Q3, 53–119 ka) terrace.
