  1. Geologists You could end up doing some of these things! OK, maybe you wouldn’t want to look like some of them…

  2. Nicholas Steno • 1638-1686 • Explained the origin of Fossils • Laws of Superposition, Original Horizontality, Principle of Lateral Continuity

  3. William Smith • 1769-1839 • Fossil succession • First Geological map of England and Wales

  4. James Hutton • 1726-1797 • Early rock cycle

  5. Sir Charles Lyell 1797-1875 • Author of The Geological Evidence of the Antiquity of Man in 1863 and Principles of Geology. • Lyell argued that, presently observable geological processes were adequate to explain geological history. • Action of the rain, sea, volcanoes and earthquakes explained the geological history of more ancient times. • Lyell rebelled against the prevailing theories of geology. He thought they were biased, since they were based on the interpretation of Genesis. He thought it would make more sense to exclude sudden geological catastrophes to vouch for fossil remains of extinct species and believed it was necessary to create a vast time scale for Earth's history. This concept was called Uniformitarianism. • He developed new ideas regarding metamorphic rocks. He said rock changes due to high temperature when they are adjacent to igneous rocks. • He discussed paleontology and stratigraphy. He said that the antiquity of human species was far beyond the accepted theories of that time.

  6. The clothes have changed, but the curiosity and style hasn’t.

  7. Louis Agassiz

  8. Antarctic Geologists with Shackleton

  9. Wegener • Plate Tectonics

  10. Antarctic volcanology • Climbing Mt Erebrus, you get up to some interesting steam vents… Some people get climbing ropes and go on in!!!

  11. Gene Shoemaker • Astrogeologist

  12. Gene… againprobably when he was teaching the astronauts field geology

  13. Working with core samples

  14. Surveying new lava flows

  15. Some rocks are a little more challenging to get to.

  16. Monitoring Mt Rainier

  17. Jack Lockwood – does he have fun or what??? • - he lives in Volcano…

  18. Fun with lava in RussiaWhat the well dressed volcanologist wears – part I

  19. What the well dressed volcanologist wears… Part II • On Kilauea – looking at the flows, trying to figure out the story – or History of the Kilauea eruptions – and the process of lava flows.

  20. David Johnson • A dedicated geologist • He was watching Mt. St. Helens from a “safe” area. He was first to see it blow up and report it. Also, the first to die as the blast hit.

  21. Geo-joke

  22. Maurice and Katia Kraft

  23. Elbert King

  24. H. H. Nininger
