The image is a photograph of a wooden sign that reads "Blue Hole" in white lettering on a brown background. The sign is located in a wooded area with trees and shrubs in the background. Below the sign, there is a set of stairs leading up to the top of the hill. The text on the sign reads "Depth: 81 ft. Diameter: 60ft. Outflow: 3000 gallons per minute. Water:Temp:61". The sign appears to be old and weathered, with some rust and discoloration visible on the wood.
