Transcript of Dinosaur Ridge VFE

Abstract:
Why does Dinosaur Ridge look the way it does?
Notes
A Virtual Fieldwork Experience
A product of PRI and its Museum of the Earth ReaL Earth Inquiry Project
Our Team!
This Google Earth and Prezi based VFE explores Colorado's Dinsaur Ridge. Content includes an impressive arrary of fossil evidence over more than a billion years of Earth history as well as aspects of what we can learn about past and present ecosystems. Evidence for past ecosystems is in the fossil record. The VFE is adaptable to many grade levels and can be completed within a class period. The activity is an exploration and does not have an associated written assignment. The Google Earth file includes pictures from more than just Dinosaur Ridge. Most photographs were taken on the Ancient Denvers field trip at the 2013 GSA meeting.

Icons for Prezi & Google Earth
A growing collection can be found in this Picasa Web Album:

Any on the current page can be copied and used within this or other Prezis.
About this VFE:
The Dinosaur Ridge Virtual Fieldwork Experience is derived from the Ancient Denvers Field Trip at the 2013 Geological Society of America Annual Meeting.
The field trip itself included more than just Dinosaur Ridge. Also included were stops at the Great Uncomformity just above the Red Rocks Amphitheater, and stromatolites in the Lykins Formation. These are older than the rocks found at Dinosaur Ridge and were visited earlier in the field trip.
The Ridge itself included the next several stops and is what is highlighted here. The field trip continued after Dinosaur Ridge, and included working through progressively younger rock.

Photos from the full day field trip, including these earlier and later stops, may be found here:

The VFE Template
Use the VFE Template to make your own VFE! See it here:
http://prezi.com/xfiwcchax-1q/vfe-template/
That's the page you're on!
Make a copy of the template and insert your own photos, text, and other kinds of files. A piece of the template is excerpted below.

Key for Icons
The icons below are used in Google Earth, Prezis and PowerPoints to indicate an iterm's intended topic focus. Several are from Google Earth's default icon set. They are also posted in a Picasa web album found here: https://picasaweb.google.com/TFG.VFE/IconsForGoogleEarthPlacemarksPrezis
Icons maybe copied within a Prezi or from Prezi to Prezi, if you are viewing in edit mode. To use them for Google Earth placemarks, open the placemark through 'Get Info' (on Macs) or 'Properties' (on PCs) and click on the pushpin icon in the upper right. Then, either select from the available set, or add the icon's URL by copying and pasting from the Picasa Web Album. A red indicates that the connected file or placemark is a teacher's edition. Additional icons will be added as time and need dictate.

Note that while there is a path through this Prezi, it is there to show a few highlights. You can move through the path by clicking the forward and reverse arrows, or by clicking your mouse.

Many elements are not on the path, and when in the actual field, researchers do not follow one set path. Therefore, you are encouraged to click off the path! Imagine yourself actually in the field. What do you most wish to explore? Go there.

Both this Prezi and the accompanying Google Earth file are intended to provide options in the content of what is explored. In a class activity, different groups might focus on different areas, either from a content perspective, or in terms of actual geographic areas. This VFE may also be visited repeatedly across the year as the content addresses many different units from an Earth, environmental, or life science class.
Note that clicked links within the Prezi open in new tabs or windows in your browser. In order to see them, exit full screen viewing of the Prezi.
Water continues to shape the landscape in the region. The more recent rock in the nearby Green Mountain Conglomerate is indicative of more extreme action by water.
