In a sun-drenched meadow dotted with yellow wildflowers and tall green grasses, four individuals are engaged in an outdoor activity. A person in a grey shirt and shorts is bending over, holding a white pole with measurement markings. To their right, a man in a dark shirt and cap, and another man in a light-colored shirt, stand near two more white poles. A woman in a light-colored jacket and dark pants, carrying a blue backpack, stands to the right of the men. Behind them, a dense forest of tall, dark green pine trees forms a natural backdrop. A large metal pylon is visible in the mid-ground, partially obscured by the trees. The scene is set against a backdrop of a bright blue sky with scattered white clouds. The location is identified as Yundola, Bulgaria.
