The site I chose for my project was an area of the Lime Ridge Open Space in Concord, CA. In the late 19th and early 20th centuries, limestone was mined in this area for cement production leaving behind a number of quarry ruins.  Digging stopped in 1946, and in 1974, the land was purchased through a bond measure. It is 2nd largest open space in CA.

There are two large areas of the open space separated by Ygnacio Valley Rd. This project site is just north of Treat blvd. The terrain is perfect for showcasing topography while still being small enough to acquire imagery in one flight.
