developed this site to supplement a laboratory course in Geological
History at Valdosta State University. Each location was chosen to represent
a specific geologic process. There is no preferred order — start
where you wish. (NOTE: so far, only Grandeur Point and West
Temple are available. The other locations will be open by the end of
summer 2005.) Each location (Grandeur Point, West Temple, Frenchman,
Loop Mountain, Boysen Peak, Palisades, Sawtooth Ridge) is divided into
subsections: Geologic Column
(an overview of sediment layers), Geologic
History (processes of deposition and erosion), Gallery
(aerial photos linked to ground photos), and Basic
Ideas (elementary processes specific to each location).
We have tried to make the navigation so that once inside a location,
the user can enter any of the three subsections from anywhere and easily
switch among them.
Column shows a stack (drawing) of all sedimentary
layers present at a given location. Clicking on the layers will show
representative photographs of the site. The photos have buttons which
draw boundaries around the specific sediments. (This is available
so far only for Grandeur Point.)
History shows how, step by step, the sediments were
laid down during each geologic period. On some pages the last button
will reveal picture frames which lead to photos of the sediments indicated.
The user can step through history using the arrow navigation buttons
or, instead, move through the pages in any order using the history
buttons on the left. The history buttons are also available from inside
the Geologic Column
Gallery of each location
shows aerial photos of the larger region. Boxes show the user where
the photos were taken. Clicking on a box delivers the reader to the
specific location and buttons reveal zoom views and boundaries around
different layers. (This is available so far only for West Temple.)
location has its own Basic Ideas
section which contains resources important to the given location.
For example: symbols used, abbreviations, and macroscopic photos and
thin sections of rock types. There are also animations which show
basic processes; for Grandeur Point, for example,we have animations
showing deposition, erosion, transgression, regression.
to use this site
have tried to make navigation as simple and intuitive as possible. However,
a good strategy to keep in mind is to move the cursor all over the page
to find hotspots you might have missed.
philosophy is to exploit web technology to provide a tool that is not
possible in a textbook, to target concepts which are traditionally challenging
for students, to be minimalist in the construction so that this site
is flexible enough to be used for different learning levels. If you
have comments or suggestions for improving this site, we would be most
appreciative to hear from you.
