OVERVIEW (1) Click on Grand Canyon (pdf) and Death Valley (pdf) above to compare the structure of the two geology charts for these parks. Note where the information on the two charts are the same and different. Many of the items on these charts are hyperlinks. Explore these hyperlinks. There are some surprises. Note also the amazing amount of the earth's histroy that is represented in Death Valley (over two billion years). (2) Red text on a chart indicates that a formation from that time period can be found in the park or region. Non-red indicates no such formation is present (missing geology). Hyperlinks in red text should be specific to the park. Hyperlinks for the latter should be generic, common to all charts. We have found it difficult to get good park-specific hyperlinks in many instances so some such links are generic. Most generic links are to Wikipedia. Some are to Palaeos. (3) The list of charts completed thus far is on the right side of this page. Printed out, these charts can be cut and folded to make a two-sided 4 x 6 card. This card can be used as bookmark (laminate it for durability). By the time you have finished the book you will have memorized much basic information about the earth's history! (4) The arrow of time on each chart is the green arrow that contains the names of the Hadean, Archean, and Proterozoic eons (right panel) and the Paleozoic, Mesozoic, and Cenozoic eras (left panel). All of these names are hyperlinks. The Phanerozoic Eon is at the bottom of the left panel. (5) At the bottom of the left panel of each chart is a link to the UC Museum of Paleontology. This site is excellent for beginners and has resources for students, including young students. The link following "For MISSING GEOLOGY notes" (bottom left panel) will lead to this chart overview. (6) Do you have a favorite park, state, or region for which you would like to have a chart? If so, send us the name of the region and the red links to existing region-specific information (this is the hard part). We will post a chart on this website for you.
