The image is a photograph of a sign on the side of a stone wall. The sign is rectangular in shape and has a blue background with white text. On the left side of the sign, there is an illustration of the Pike Hill Signal Tower, which is a small wooden structure with a sloping roof and a chimney. The tower is located on a hilltop with a grassy area in front of it. 

On the right side, there are two smaller illustrations of the tower, one of which shows a group of people standing on the ground and the other of which is an aerial view of the ruins. The ruins are made of stone and appear to be old and weathered. The sky is blue and there are a few clouds in the background.

The sign is placed on a gravel path next to the wall, and the shadow of a person can be seen in the bottom right corner of the image.
