100 Things Meme Stolen From http://harmonictremors.blogspot.com/2009_02_01_archive.html

The ones I've done/seen are in bold. Comments are in italic.

1. See an erupting volcano
2. See a glacier - Seen some cirqes and glacial valleys
3. See an active geyser such as those in Yellowstone, New Zealand or the type locality of Iceland - Old Faithful and Steamboat, plus a few other unnamed ones near Yellowstone Lake.
4. Visit the Cretaceous/Tertiary (KT) Boundary. Possible locations include Gubbio, Italy, Stevns Klint, Denmark, the Red Deer River Valley near Drumheller, Alberta. - Driven over it a few times, but have never stopped and looked for iridium-red layers.
5. Observe (from a safe distance) a river whose discharge is above bankful stage
6. Explore a limestone cave. Try Carlsbad Caverns in New Mexico, Lehman Caves in Great Basin National Park, or the caves of Kentucky or TAG (Tennessee, Alabama, and Georgia) Been to Carlsbad, NM and Cueva del Hato, Curaçao
7. Tour an open pit mine, such as those in Butte, Montana, Bingham Canyon, Utah, Summitville, Colorado, Globe or Morenci, Arizona, or Chuquicamata, Chile. Visited a rehabilitating open pit mine in Elko, NV
8. Explore a subsurface mine.
9. See an ophiolite, such as the ophiolite complex in Oman or the Troodos complex on the Island Cyprus (if on a budget, try the Coast Ranges or Klamath Mountains of California).
10. An anorthosite complex, such as those in Labrador, the Adirondacks, and Niger (there's some anorthosite in southern California too).
11. A slot canyon. Many of these amazing canyons are less than 3 feet wide and over 100 feet deep. They reside on the Colorado Plateau. Among the best are Antelope Canyon, Brimstone Canyon, Spooky Gulch and the Round Valley Draw. Hiked several in Death Valley
12. Varves, whether you see the type section in Sweden or examples elsewhere.
13. An exfoliation dome, such as those in the Sierra Nevada. - Maybe. I've definitely seen a lot of Sierra Nevada laccoliths.
14. A layered igneous intrusion, such as the Stillwater complex in Montana or the Skaergaard Complex in Eastern Greenland. - Does writing an emergency LMI lecture count?
15. Coastlines along the leading and trailing edge of a tectonic plate.
16. A gingko tree, which is the lone survivor of an ancient group of softwoods that covered much of the Northern Hemisphere in the Mesozoic. There are several on the street where my mom lives
17. Living and fossilized stromatolites (Glacier National Park is a great place to see fossil stromatolites, while Shark Bay in Australia is the place to see living ones) Marquette, MI
18. A field of glacial erratics
19. A caldera - Yellowstone plus just about all of the San Juan calderas, also known as my master's project field area.
20. A sand dune more than 200 feet high - I think the big one in Death Valley's about that large. If not, it's close.

32. Fluorescent and phosphorescent minerals We have more than a few in my building, given IL's state mineral is fluorite!

34. Lava tubes Snow Canyon, UT and a small one preserved in the Precambrian(!) basalts of Mamainse Point
35. The Grand Canyon. All the way down. And back. Little Grand Canyon of the San Rafael Swell doesn't count, does it?

61. The moving rocks of Racetrack Playa in Death Valley - Still sad we couldn't talk our petrologist emeritus extraordinaire to let us go!
62. Yosemite Valley
63. Landscape Arch (or Delicate Arch) in Utah - Better yet in early March, when it was cold, windy, a bit snowy, and outright miserable, which meant we got the most INCREDIBLE shots because no one else was crazy enough to be there when we were!
64. The Burgess Shale in British Columbia
65. The Channeled Scablands of central Washington
66. Bryce Canyon - Seen it from afar. It was still too cold/snowy at its elevation to make a visit there worthwhile.

83. Find dinosaur footprints in situ - Nope, just the teaching sample from GEOL 107
84. Find a trilobite (or a dinosaur bone or any other fossil) - Got a bitty-bite on a field trip I drove for last semester, but left it in the university SUV. : ( Good thing I still have a map to that locale!
85. Find gold, however small the flake - I don't think the gold-, silver-, and pyrite-bearing vein material we were allowed to poke around in during a field camp project counts . . .
86. Find a meteorite fragment
87. Experience a volcanic ashfall - If I were to experience this, it's probably mean I was too close to the eruption!
88. Experience a sandstorm - Seen a few dust devils outside of Vegas. : D
89. See a tsunami - Totally counting watching the tsunami-cams from CBS Hilo yesterday!
90. Witness a total solar eclipse - Almost. We had a near-total eclipse during school when I was in second grade. I got to watch the whole thing because my mom is awesome and brought in material to allow my class to watch it safely.
91. Witness a tornado firsthand. Unfortunately no, but it's one of my life's goals. I've seen a couple of funnel/wall clouds and an actual DOUBLE ANVIL cloud east of the Front Range in Colorado.
92. Witness a meteor storm, a term used to describe a particularly intense (1000+ per minute) meteor shower - This sounds awesome!
93. View Saturn and its moons through a respectable telescope. Have seen Saturn, plus Jupiter and the four Galilean moons. Awesomeness.
94. See the Aurora borealis, otherwise known as the northern lights. Thought it was a cloud refracting a remnant of sunlight till my dad recognized it for what it was.

99. See noctilucent clouds - Think I have a couple of times; once during a night drive to the U.P. which couldn't be explained by anything else.
100. See the green flash - Been watching Lake Superior sunsets most of my life, watching for the Green Flash. Finally saw one in Curaçao and had a massive geekgasm in front of EVERYONE. If I remember correctly, the trip videographer caught the entire sunset on camera and hopefully didn't have the microphone on!
