This park is about 15 miles from Roswell. The Bottomless Lakes are really sinkholes and they are not bottomless. There are 9 lakes, and they range from 17-90 feet deep. They are thought to be given their name by cowboys who tied ropes together to try and reach the bottom, but the ropes weren't long enough, so they thought the lakes were bottomless. The greenish blue color created by algae and other aquatic plants also added to the illusion of great depth.
