What was the secret to good health at Camp Green Lake 110 years before Stanley was sent there?

The secret to good health at Camp Green Lake 110 years before Stanley was primarily the availability of fresh water and a thriving ecosystem, which supported a variety of plant and animal life. The camp was once a lush area with abundant resources, allowing for a healthy lifestyle and a balanced diet. However, over time, the lake dried up, leading to harsh living conditions that contributed to the camp's transformation into a punishment facility for troubled boys. This shift drastically impacted the health and well-being of its inhabitants.
