This article covers several features and areas that demonstrate the catastrophic processes that shaped the Northwestern US.

Any of the proposed resolutions to the conflict between radiometric dating and biblical chronology has problems. The pros and cons of each need to be considered.

Research in the Yellowstone "fossil forests" includes study of the sediments, purported paleosoils, and paleoecology. Together, these indicate the "forests" are not in situ, but have been transported. Comparison with the effects of the eruption of Mt St Helens and the floating log raft in Spirit Lake provide an example of a possible mechanism for emplacement of the fossil trees in Yellowstone.

Radiometric dating is an interpretive science. The complex chemical and physical processes taking place within Earth's mantle and crust are neither completely known nor understood. This is especially true when the radioactive isotope parameters are considered.

One of the most interesting challenges in understanding Earth history is explanation of the order in the fossil record. Study of fossil patterns and trends should help improve our understanding of the underlying processes. Published in Origins v. 23, n. 2.

Various examples adequately establish that a radioisotope age does not necessarily have a real-time significance. A relationship of a radioisotope age with real-time must be based on an interpretation.

Ancient fossil reefs are considered to be a challenge to the biblical concept of creation. But do these fossil reefs really negate the biblical account of beginnings? Published in Origins v. 21, n. 2.

Coconino Sandstone research has demonstrated how catastrophists can use their theory to develop specific hypotheses about a geologic feature (the Coconino Sandstone), and successfully carry out scientific research to test that hypothesis. This is one criteria that science used to determine the scientific value of any theory.

The catastrophic burial of plant debris and its subsequent change to coal is not accepted by most coal geologists. However, the dominant "peat bog" theory presents problems that have remained unanswered for more than a hundred years. A Flood model for the formation of coal answers some of these problems and provides a scientifically reasonable explanation for the origin of the vast quantities of coal that exist worldwide.

The fact that animals need plants poses a problem for the evolutionary model, since the record of past life sometimes reveals non-viable ecosystems. Published in Origins v. 21, n. 1.

It is unwarranted to assume a priori, as in the past that all upright petrified trees had grown in the place where they are now found. The transport of trees and their deposition in an erect stance is not as unlikely or as rare as might be expected. Upright fossil trees within the geological column are compatible with a Flood model. Actually, when all factors are considered, a catastrophe involving water and many floating trees is a more satisfactory explanation for their origin.

Microorganisms can exist in rocks several kilometers below the surface of the earth. Recently a number of reports indicate that these organisms are much more common than previously surmised and that vast regions of the underworld may be inhabited. Published in Origins v. 19, n. 2.

The pipes and dikes in Kodachrome Basin have come from the sedimentary layers below, and raise interesting questions regarding the amount of time involved in their formation. Published in Origins v. 19, n. 1.

The unnatural mixture and the rapid stratigraphic shifts of fauna seem to require catastrophic water transport into the area. The large geographic extent precludes a local event. Creationists suggest that a world-wide flood could produce results as seen in the Santana Formation and is a better explanatory model.

The approach outlined in this paper suggests that the radiometric age assigned to the inorganic minerals associated with a fossil is more a reflection of the characteristics of the source of this inorganic material than an indication of the age of the fossil. Published in Origins v. 17, n. 2.

A model of an ice age caused by the Genesis flood is summarized. It proposes solutions to a number of ice-age problems. Published in Origins v. 17, n. 2.

Geologic features of the KT boundary present interesting evidence relating to possible causes of the mass extinction. The widespread existence of the boundary clay has been interpreted as evidence for a worldwide event at the boundary. Published in Origins v. 17, n. 1.

Most punctuated equilibria theories explain why proposed exceptions tend to be in the Upper Cenozoic. Punq Eq Creation Style, however, not only predicts the stasis and abrupt appearance of species, but it also predicts that exceptions will be found in the Upper Cenozoic among forminifera. Because of its greater explanatory power, PECS teoyr is superior to other PE theories. Published in Origins v. 16, n. 1.

The layers of sedimentary rock that we see over the surface of the earth usually appear as parallel features that are often spread over wide areas. What does not appear to the casual observer is that between some of these layers major portions of the geologic column are missing. Published in Origins v. 16, n. 2.

Foraminifers exemplify many of the problems of fitting the fossil record into a short chronology, including thousands of named species and apparent evolutionary sequences. Any short-time creationist model must be able to explain these features. Published in Origins v. 15, n. 1.
