The image depicts a fast-flowing, dark-watered stream situated within a densely forested area of the Smolyan municipality, Bulgaria. The stream occupies the central frame, exhibiting significant white turbulence and rapids as it cascades over submerged rocks and a rocky streambed. Tall, dark green coniferous trees, consistent with firs or spruces, form a dense canopy on both steep banks, obscuring the sky. Their trunks and branches are visibly covered in green moss and lichen. The banks also feature scattered bare deciduous branches, smaller saplings, moss-covered boulders, and fallen organic debris. No human individuals, animals, or man-made structures are present. The scene is illuminated by diffused natural light, indicating either an overcast condition or deep shade from the overhead foliage.
