Continuing the line of summits in a Southeasterly direction, the Bolkar Mountains are bounded by the Göksu river to the West and the Pozanti river to the East.The Northern part of the mountains lies in Nigde province while the Southern peaks rise in Mersin province. These mountains exhibit interesting geological characteristics. Made of sedimentary material such as limestone and dolomites, the range reveals excellent examples of nappes, or folds in the layers of rocks. There are vast formations of karst as well as landscapes that reveal the effects of glacier and water erosion. Despite this erosion, no real water network has developed on the mountains. Because of the sedimentary nature of the rocks, water is absorbed creating large areas of karst, such as Pozanti and Sekerpinari.

The highest peaks of the Bolkar are: Medetsiz (3524 m.) Kesifdagi (3475 m.), Koyunasagi (3426 m.), Tahtakaya (3372 m) and Egerkaya (3347m.)

The Northern flank receives the most exposure to snow and glacier formation; it is nevertheless the best route for an ascent to the highest summits of the Bolkar.

 

 

The Northeastern extension of the Central Toros (Taurus) range, the Mercan range, straddles both the Tunceli and Erzincan provinces. Mt. Akbaba, at 3462 metres, is the highest summit in the Mercandagi range. The limestone geology of these mountains creates their very rugged profile.

Erzincan, a major city North of the mountain range and accessible by air, rail and road, is the base from which to attempt an ascent on the North face.

Those wishing to climb the mountain from the South begin their trek at Ovacik in the middle of the Munzur mountains. Climbers entering from this point can reach the highest summits of the Munzur. Ovacik lies 70 kilometres from Erzincan and is accessible by a road which follows the banks of the Munzur valley. The Munzur River, which rushes through a national park, tempts tourists with superb fresh fish and beautiful mountain scenery.
