Welcome to the Geology Wing Exploring this series of exhibits will take you on a journey through the history of the Earth, with stops at particular points in time to examine the fossil record and stratigraphy. The Geology Wing is organized according to the geologic time scale. If you wish to begin browsing now, click on any division of the time scale below You might wish to start in the Cenozoic Era (65 million years ago to the present) and work back through time, or start with Hadean time (4.5 to 3.8 billion years ago) and journey forward to the present day. No matter "when" you start, don't forget to stop along the way to learn about the stratigraphy, ancient life, fossil localities, and tectonics of the various time periods. Here are three links that can help to speed your journey: Get helpful hints on navigating the Geology Wing Read about the history of the geologic time scale , and find out more about how it is organized. Jump to a specific time period using the UCMP Geological Time Machine Last but not least, don't forget to visit our exhibit on Plate tectonics , an important geological concept in any time period!

25. Geology Humor You might be a geologist if . and A brief guide to scientific literature. http://www.geoscience.org.za/economic/humor.htm

Geologists are amazing. They know hundreds of words for different sorts of dirt and hundreds of words for things it does when left alone for a few million years. (By: Thomas Kettenring) You Might Be a Geologist If ... You own more pieces of quartz than underwear. Your rock collection weighs more than you do. Your rock garden is located inside your house You can pronounce the word "molybdenite" correctly on the first try. You don't think of "cleavage" the same way everyone else does. You have ever uttered the phrase "have you tried licking it" with no sexual connotations involved You think the primary function of road cuts is tourist attractions. You find yourself compelled to examine individual rocks in driveway gravel. You're planning on using a pick and shovel while you're on vacation. Your internet home page has pictures of your rocks. You will walk across eight lanes of freeway traffic to see if the outcrop on the other side of the highway is the same type of rock as the side you're parked on. You can point out where Tsumeb is on a world globe. The baggage handlers at the airport know you by name and refuse to help with your luggage.

38. Natural History St. Helena is a volcanic island although volcanic activity has long since ceased. The last volcanic eruptions occurred about 7 million years ago and since that time the island has been sculpted into its present form by the forces of erosion. http://geowww.ou.edu/~bweaver/Ascension/sh-nat.htm

Natural History of Saint Helena Saint Helena has a fascinating natural history. Unfortunately, as is all too common on oceanic islands, the endemic flora and fauna has suffered the ravages of human habitation of the island; introduced animals and deforestation have almost completely destroyed the lush tropical wilderness described by the earliest visitors to St. Helena (only about 10% of the island is now covered by semi-natural forest). Encouragingly, there has been recent recognition of the importance of conservation and re-introduction of the endemic flora; the establishment of the Diana's Peak National Park, the gumwood reforestation project at the Millenium Forest , and formation of the St. Helena National Trust are very positive steps. Geology St. Helena is a volcanic island although volcanic activity has long since ceased. The last volcanic eruptions occurred about 7 million years ago and since that time the island has been sculpted into its present form by the forces of erosion. The sea has carved the sheer cliffs that ring the island and streams have incised the deep v-shaped valleys. The oldest volcanic rocks on St. Helena are about 14 million years old and are exposed in the northeastern part of the island and form the Northeastern Volcanic Centre which remained active until about 11 million years ago. At that time the centre of volcanic activity jumped to the southwestern part of the island where activity persisted until 7 million years ago; the volcanic products of the Southwestern Volcanic Centre have been divided into three separate phases of activity. The

The Geology of the Grand Canyon How was it formed? Where did all the rock come from? Why does it look like it does? When did all this happen? clickable image map Slopes of Dox Formation near Unkar Creek How was it formed? The truth is that no one knows for sure though there are some pretty good guesses. The chances are that a number of processes combined to create the views that you see in todays Grand Canyon. The most powerful force to have an impact on the Grand Canyon is erosion, primarily by water (and ice) and second by wind. Other forces that contributed to the Canyon's formation are the course of the Colorado River itself, vulcanism, continental drift and slight variations in the earths orbit which in turn causes variations in seasons and climate. Water seems to have had the most impact basically because our planet has lots of it and it is always on the move. Many people cannot understand how water can have such a profound impact considering that the Canyon is basically located in a desert. This is one of the biggest reasons that water has such a big impact here. Because the soil in the Grand Canyon is baked by the sun it tends to become very hard and cannot absorb water when the rains to come. When it does rain the water tends to come down in torrents which only adds to the problem. The plants that grow in the Grand Canyon tend to have very shallow root systems so that they can grab as much water as possible on those rare occasions when it does rain. Unfortunately these root systems do nothing to deter erosion by holding the soil in place. Now you've got lots of water, no place for it to go, but down to the
