Rhodope Mountains, Bulgaria February, 1994 Extending 200 miles (320 km) along the border of Bulgaria (bottom of the image), and Macedonia, Greece (south or toward the top of the image), the Rhodope Mountains can be seen in this southwest-looking view. With the higher peaks of the Rhodope Mountains covered with snow, the rugged range has few passes. The range lies between the Balkan Mountains to the north (bottom right) and the Aegean Sea (upper left) to the south. Near the bottom center of the view, the Maritsa River Valley can be identified. In the upper left portion of the image, the Greek island of Thasos can be seen.
