The image shows a tall wooden sign in the middle of a wooded area. The sign is rectangular in shape and has a green border with the word "RESERVABLE" written in white letters. On the top of the sign, there is a yellow arrow pointing to the right with the number 90 written on it. Below the arrow, there are two white signs with black text. The signs appear to be warning people to stay away from the area. In the background, we can see trees and a picnic table. The ground is covered in grass and there are fallen leaves scattered around.
