Excavating the Mounds

It wasn't until the 1930's when it was decided to excavate the mounds. Under President Roosevelt the WPA (Works Progress Administration), sent in a professional team. They dug up pieces of several different mounds and were shocked with some of their discoveries. The architecture of some mounds showed that the people were not only very civilized, but also very intelligent. They had used the different soil types (clay in particular) to construct the sturdy and lasting mounds that we still see today. Also, the team in the 30's dug up some artifacts that contributed to the knowledge that the people there were somewhat sophisticated as well. The excavation team later realized after digging up several sets of human bones that at least one of the mounds was a burial mound. The pictures below are of the Great Temple Mound and of some artifacts that were dug up during the excavations.

WATER - How were the Great Lakes formed?

Having grown up in Wisconsin, I've heard a lot about the Great Lakes. That being said, a new question was brought to mind during class the other day. In class we were learning about how lakes were formed, and that made me wonder what it was that carved out these massive lakes.

The site above is what I used to find my information.

According to this site, the primary cause for the formation of these lakes is glacial erosion. Around 14,000 years ago, the Lauren Tide (a mass of glaciers covering most of Canada and northern parts of the US), started to shift to the South as the climate warmed and they continued to melt and refreeze. Eventually the glaciers carved out the massive indentations that would slowly (via rain and the glacier melting as it passed) fill with water and become the Great Lakes that we now know.

EXTREMOPHILES

THERMOPHILES

Found in geothermally heated regions of the earth, Thermophiles can survive between 115 and 175 degrees Fahrenheit. They can be found in hot springs like those in Yellowstone National Park.

ACIDOPHILES

Like thermophiles, acidophiles can survive in extreme conditions. Their specialty isn't necessarily heat though. They can survive in extremely acidic conditions. Most of the time with a pH level of 2.0 or below. They are usually bacteria type organisms.

HALOPHILES

Like the other 2, halophiles are also usually bacteria type organisms. They can survive in extremely salty conditions. In comparison, most similar type organisms would dissolve or not be able to function properly in such salty conditions. They are very prominent in salty bodies of water like the Great Salt Lake in Utah.

GEOLOGY

3 main types of Rocks - IGNEOUS, SEDIMENTARY, METAMORPHIC

Igneous Rocks are formed when molten lava cools and hardens over time (also known as intrustive igneous rock), or when the crust meets the mantle and previous content is melted and hardened into rock (extrusive). Examples: Pumice and granite

Pumice

Sedimentary rock is formed by the collection of rocks and materials at the surface of the earth and in bodies of water. Typically the layers in sedimentary rock makes it easy to tell how it was formed and over how long it took to form. Examples: sandstone and chalk

Sandstone

Metamorphic rocks are exactly what they sound like, rocks that have mophed into something new. Either  igneous, sedimentary or older metamorphic rock, under extreme pressure and heat and be caused to change both physically and chemically. Once a rock changes its form like this, it is considered a metamorphic rock. Examples: Marble, which is metamorphosed limestone and Slate, which is metamorphosed from shale or silts.

SOILS

Link: The 12 Soil Orders of the World

Georgia's soil is most well-known for it's kaolin clay production. It is also rich in marble, barite and bauxite. (Georgia Soil and Rock content)

As far as the soil orders goes, there is an abundance in ultisols, inceptisols, and alfisols.
(Georgia Soil Orders)

Georgia Soil can be rich in clay, hence the redish color to this Georgia soil image sample.

You can identify a soil by its color. Typically, depending on the soils contents, the color and "chroma" can help you identify what type of soil it is. The most commonly used source for soil identification is the Munsell Soil Color Chart (Munsell Soil Chart Online)

The following images are maps of the soil regions in Georgia. Because of the fact that Georgia has both a coastline and a mountain line on either side, the soil types can be very different on either side of the state.

This is an image of the route traveled during our geocaching experiment. Each of the angles is where 1 of the 8 total destinations were. After the walk was over, google earth estimated the distance walked at 0.26 miles. I will say that it is slightly more than that, considering that the route I drew on the computer is cutting corners between pinpoints.

Geocaching is a fun way to get outside, off your feet, and do some natural environment adventuring. There are geocaches (or destinations with placed objects) all over the world, marked out by GPS. If you're ever in the mood for a real life treasure hunt or just some fun walking around, then geocaching is a cool way of recording your findings. You can even go onto the website I linked to above and blog or post about your findings and see what others had to say about those very same locations! I think going on a neat little geocaching adventure would make for a good date, and maybe, if your smart, you'll make the last destination a romantic one with a Valentine's Day gift waiting. "Tis the season.
