While looking at the map of the United States, I decided that I wanted to choose an area that had high elevation differences, and so I chose an area located in Central California. The area I ended up choosing was where the following four counties met, Mona County, Fresno County, Madera County, and Inya County. Instead of telling a little about each county, I decided to write just about one. The one I chose was Fresno County. It was founded in 1856 and is currently just over 6,000 square miles. Fresno is also the tenth most populated county in California. It is considered to be the most agriculturally rich county in the United States and currently supplies food to companies such as Sun-maid Raisins, Del Monte Foods, and Kraft just to name a few. On the east is the Sierra Nevada mountain range, which is featured in the above maps. The Sierra Nevada mountain range currently stretches 400 miles and runs both in California and parts of Nevada. Development of the surrounding areas is highly regulated and much of it is protected by the National Park Service.
