Paleokarst systems owe their complex geometries to the interaction between the karst aquifers and the host rock being dissolved. The majority of paleokarst research to date has considered dissolution of carbonate strata (James and Choquette 1987), but rapid and extensive dissolution of interstratified evaporites can be an important if largely undocumented style of paleokarst that may play an important role in near-surface environmental settings as well as providing a unique style of reservoir heterogeneity in the subsurface (Sando 1967, 1974, 1988; Smith et al. 2004). This study is designed to answer the question, “How do we recognize evaporite paleokarst as distinct from standard meteoric carbonate paleokarst?” using spectacular, laterally continuous exposures in the upper Madison Formation within Bighorn Canyon, Wyoming. Key characteristics of the Madison intrastratal evaporite karst complex were documented and contrasted with the top-Madison surficial karst system resulting in a suite of data that includes detailed section measuring, facies mapping using high resolution photo panels and ground based LiDAR for control. Hand samples, thin sections and x-ray diffraction analysis also contributed to this study. High resolution mapping of key surfaces, karst facies and petrophysical properties were used to develop a stepwise evolutionary model of the evaporite removal paleokarst complex. The interplay between surficial karstification, solution enhanced fractures, subsurface intrastratal evaporite dissolution, collapse and infill, were considered in constructing this model. Similar to standard meteoric paleokarst systems, the Madison evaporite paleokarst has been divided into 7 distinct karst “facies” including laminated cave floor fill, roof collapse chaotic breccias, and suprastratal dissolution complexes. Features proposed to be unique to evaporite paleokarst that will aid in future studies are (1) presence of relic gypsum breccia clasts within cave-fill facies, (2) the near absence of cave pillars or roof touch down within the chaotic breccia zones, indicating removal of a laterally extensive soluble stratum, (4) a striking absence of sub-cave floor breccias or fractures, (5) a distinct breccia matrix consisting of primarily autochthonous detrital dolomite with a minor component of allochthonous detrital clays from the overlying Amsden, suggesting that the bulk of the breccia matrix is locally sourced insoluble residue from evaporite dissolution, and finally (6) close facies associations of the depositional sequence suggesting that evaporites were a likely part of the original stratigraphic record in the Madison. These criteria are considered to be a solid starting point for an evaporite paleokarst model and should assist in the recognition of similar paleokarst breccias in the ancient rock record. / text

The intention of this thesis is to draw attention to a much neglected part of women's suffrage history - that is, a comparative analysis of the suffrage movements in New Zealand and the United States. Historians have dismissed any suggestion of similarities between the two groups because' of the obvious differences in size and the time taken to gain the vote. However, this study reveals parallels between the two movements in terms of membership, leadership, ideologies and opposition. This is particularly highlighted in the comparison with Wyoming. These similarities, together with New Zealand women's new found 'prestige' after having won the vote, led to close relations between women of the two countries, as revealed in personal correspondence. By the late l890s United States suffragists had changed direction in both their tactics and arguments for suffrage and this, together with distance and a lack of time and money, meant that New Zealand suffragists aid was confined to emotional support rather than practical assistance. This study was, to a certain degree, limited by the lack of availability of United States primary sources. However, the Kate Sheppard Collection contains a wealth of correspondence between the New Zealand and United States suffragists and provides ample information to support the thesis. Prior to the examination of the interaction of the suffrage movements in New Zealand and the United States, we will first of all begin by considering the broader context of women's role in society. This is will be followed with a study of -the historiography of women's suffrage in Wyoming and New Zealand. We will then proceed to a comparative analysis of the leaders and supporters of the two movements. In New Zealand the women's suffrage and women's temperance organizations were inseparably linked, hence the comparative natured analysis dictates that points for comparison should be made in relation to the temperance origins of suffrage in the United States and New Zealand and to leaders with temperance links.

Time-dependent behavior of natural and excavated slopes in sedimentary rocks is a subject that is poorly understood at present but that is now an important consideration in the design, operation, and reclamation of energy-extraction facilities, in part because of the environmental considerations mandated by the Surface Mining Control and Reclamation Act of 1977 (Public Law 95-87). A slide in an abandoned, unreclaimed strip mine northwest of Sheridan, Wyoming, has been analyzed as an example of a long-term slope failure in the region. This slide occurred in early 1975, some 20 years after cessation of mining. This investigation used Spencer's limiting equilibrium method and an elastic-plastic finite element method incorporating the Drucker-Prager yield criterion. This slide was found to fit the model for time-dependent failure proposed by Nelson and Thompson (1977) in which the time to failure is related to Skempton's residual factor. The Nelson-Thompson hypothesis is extended for use with the three-dimensional Drucker-Prager yield criterion. The residual factor (R) may be computed from the factors of safety with respect to peak (F(p)) and residual (Fᵣ) material properties, using either the Mohr-Coulomb or Drucker-Prager criterion, by the relationship R = [(F(p) - 1)/(F(p)-Fᵣ)] At the present time, the Spencer limiting equilibrium analysis is a more usable tool for ordinary slope design than the elastic-plastic finite element analysis because of the speed, simplicity, and ease of including the effects of ground water in the Spencer analysis.
