Spanish Influenza
The horrible pandemic of the Spanish Influenza spread across the world between June 1918 and December 1920. The origin is unknown. Most victims were healthy young adults. Between 50-100 Millions deaths where believed to be a result of this flu. This makes it one of the deadliest natural disasters in human history. In one Macon cemetery 160 people are buried as a result of the Spanish Influenza.
Ocmulgee Indian Mounds
The Ocmulgee Indian Mounds are preserved as a national monument. It has been said that humans have inhabited the site for 17,000 years. It is a sacred site of the Mississippian Indians. It includes a burial site and an earth lodge. The Mississippian Indians still consider it sacred land today. It makes me very sad that we took this land away from the Mississippian Indians.

THE BURGESS SHALE!
The Burgess Shale contains the best record we have of Cambrian animal fossils. One of the earliest fossil beds in the world. And it is special because it is containing imprints of soft bodied animals.. If you can call those little guys animals. It is located in the Canadian Rocks of British Columbia. It is 505 years old!! And it was discovered by the great Paleontologist Charles Walcott.
Below are some images of the fossils found!

SCARYYYY!!!!!

This is what the excavation site looks like!

Water! Pastorious Park Pond
The water I have chosen is a pond in a dog park that happens to be directly across the street from my house. The park is called Pastorious Park and its located in Philadelphia, PA. While the pond is probably not as polluted as the ponds in center city Philadelphia, the pollution in this pond is a concern to me. Sense I was little my dogs have always gone swimming in this pond. And my little brother has occasionally taken a dip in the pond. (Against my parents will)..
My dogs drink this water and sometimes swim in it. Which then leads to them tracking it through my house. So I was concerned with what exactly they are tracking through my house. And also what is coming off on my hands when I pet them.
When searching for test results I found a few things. The first is that the 3 pump system that is supposed to circulate the water around the pond (an attempt to keep it clean) is not the correct system for this pond. So the pumps get clogged, and little cleaning is taking place. This completely explains why the pond always looks disgusting. However, the cost for a new pumps cost was estimated 8,000-10,000 dollars.
They are putting anti-algae enzymes into the pond. Which they clam to be working.. This may be true. But makes me concerned for what this pond would look like if they were not using these. Because the greenish brown thick mucky water does not seem like it could get any worse.
Another problem is that when it rains the pesticides and weed killing chemicals run into the small pond. Which increases nitrogen levels and spurs the growth of more algae. As stated by Joel Hoffmann who wrote an article on the pond. And people obviously want their park to look pretty, so they are going to continue using these things that pollute the pond. So as they release anti-algae enzymes into the pond, it seems it might be getting canceled out by these pollutants..
Officials say there is no immediate danger being caused by the pollution and algae in the lake. However, the pond is not meant to swimming or playing in. It seems like if there is no immediate solution for clearing up my little pond. While it would be nice for people that visit the park to have a more clear pond, the only solution is to expensive. I am glad I am now more educated about what is happening around me. I will no longer just thing what a gross pond, now I know why it that way!
Here is a picture of the cute little dirty pond!

12 Soils Orders
Above is a map of the world with the 12 Soil Orders shown. All 12 can be seen on the key on the left of the map. In the state of Georgia Mollisols are the most popular.
Here are 12 Soil Orders-
Gelisols- soils with permafrost within 2 m of the surface
Histosols- organic soils
Spodosols- acid forest with a subsurface accumulation of metal-humus complexes
Andisols- soils formed in volcanic ash
Oxisols- Intensely weathered Soils of tropical and subtropical environments.
Vestisols - clayey soils with high shrink/swell capacity
Aridisols- CaCO3-containing soils of arid environments with subsurface horizon development
Utilisols- strongly leached soils with a subsurface zone of clay accumulation and <35% base saturation
Mollisols- grassland soils with high base status
Alfisols- moderately leached soils with a subsurface zone of clay accumulation and >35% base saturation
Inceptisols- soils with weakly developed subsurface horizons
Entisols- soils with little or no morphological development
