Lab 9 - Exploration of the Toadstool GIS database.

Lab goals: The purpose of this lab is to: 1) teach you how to navigate in and complete some simple tasks with ArcGIS 9 software, and 2) learn about the structural geology of Toadstool Geologic Park in northwest Nebraska. This and other localities in the central Great Plains offer us the opportunity to investigate episodes of intraplate strain. Joints, veins, arrays of small faults, and subtle flexures combine with intraplate earthquakes to indicate that while the interior of plates are relatively 'rigid' they do deform a bit. This subtle deformation can be quite important for fluid migration, erosional patterns, and erosion/deposition dynamics. Later on in the semester you will build your own small GIS database for some locality of Great Plains strain.

What you should turn in: Having navigated and manipulated the database information in ArcGIS 9 a little I would like you to explore what might be learned from this type of data in a GIS environment. Come up with three simple statements that describe some aspect of the pattern of faulting, and then print of an image to support each statement. The image should have a scale. Come up with two statements that summarize something about vein attributes. Again you should support your statements with exemplary images. Choose the wording of your statement carefully. So your final hardcopy product will be 5 one-sentence statements, connected to 5 map images.

Navigating in the ArcGIS environment: The below is intended to be step-by-step instructions to help you complete this lab. You might check them off as you complete them.
