The complicated geological past of the region is obvious from the morphology of Olympus and its National Park. Features include deep gorges and dozens of smooth peaks, many of them in altitude of more than 2,000 metres (6,600 ft), including Aghios Antonios (2,815 metres (9,236 ft)), Kalogeros (2,700 metres (8,900 ft)), Toumpa (2,801 metres (9,190 ft)) and Profitis Ilias (2,803 metres (9,196 ft)). 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 - 2,918 metres (9,573 ft)). It is Greece's highest peak. Then, on the right is Stefani (or Thronos Dios [Throne of Zeus - 2,902 metres (9,521 ft)]), 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 peak - 2,912 metres (9,554 ft)) completes an arc of about 200 degrees, with its steep slopes forming on the west side, like a wall, an impressive precipitous amphitheatrical cavity, 700 metres (2,300 ft) in depth and 1,000 metres (3,300 ft) 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.[citation needed ]
