that followed, the ice melted and the streams that were created swept away large quantities of crushed rock in the lowest places, forming the alluvial fans, that spread out all over the region from the foothills of the mountain to the sea. The Geological Museum of Mount Olympus, located in Leptokarya, provides detailed information about the geological structure of the mountain. Morphology The complicated geological past of the region is obvious from the morphology of Olympus and its National Park. Features include deep gorges and lots of smooth peaks, many of them over , including Aghios Antonios (), Kalogeros (), Toumpa () and Profitis Ilias (). However, it is the central, almost vertical, rocky peaks, that impress the visitor. Over the town of Litochoro, on the horizon, the relief of the mountain displays an apparent "V", between two peaks of almost equal height. The left limb is the peak named Mytikas (or Pantheon). It is Greece's highest peak. Then, on the right is Stefani (or Thronos Dios [Throne of Zeus]), which presents the most impressive and steep peak of Olympus, with its last sharply rising 200 meters presenting the greatest challenge for climbers. Further south, Skolio ( second highest sub-peak – ) completes an arc of about 200 degrees, with its steep slopes forming on the west side, like a wall, an impressive precipitous amphitheatrical cavity, in depth and in circumference, the 'Megala Kazania'. On the east side of the high peaks the steep slopes form zone like parallel folds, the 'Zonaria'. Even narrower and steeper scorings, the 'Loukia', lead to the peak. Οn the north side, between Stefani and Profitis Ilias, extends the Muses' Plateau, at , while further south, almost in the center of the massif, extends the alpine tundra region of Bara, at an elevation of . Olympus has numerous ravines and gullies. Most distinguishable of the ravines are those of Mavrologos-Enipeas (14 km) and Mavratzas-Sparmos (13 km) near Bara and 'cut' the massif in two oval portions. On the southern foothills the great gorge of Ziliana, 13 km long, consists of a natural limit that separates the mountain from Lower Olympus. There are also many precipices and a number of caves, even nowadays unexplored. The form and layout of the rocks favor the emergence of numerous springs, most of them lower than 2,000 m, small seasonal lakes and streams and a small river, Enipeas, with its
