This nighttime image depicts a marker at Vetrushka Peak (1158m altitude), located in the Lyulin Mountains near Pernik, Bulgaria. A weathered, vertically oriented concrete or metal pole, painted in the white, green, and red stripes of the Bulgarian flag, stands centrally in the frame. The red paint at the bottom shows significant peeling and deterioration, while the green and white sections above are also chipped. Attached to the upper section of the pole is a rectangular white sign with black Cyrillic text reading "вр. Ветрушка 1158м.", identifying the peak and its elevation. Above the sign, a Bulgarian flag, white, green, and red horizontally striped, is affixed to the pole, partially furled. The flag appears slightly illuminated from the front, highlighting its creases. The background consists of a dense, dark silhouette of coniferous trees, indicating a forested environment. The sky above is dark and overcast, with a faint, diffuse luminescence suggesting a distant light source or light pollution. The ground in the foreground is dark and uneven, with minimal discernible detail due to the low light conditions. No people, specific actions, or interactions are visible within the scene.
