Karaca Cave


Geographical Location and Arrival


Karaca Cave situated within the borders of Cebeli Village of Torul District is 17 km. far from the city center and 1550 m. High above the sea level. It can be reached following an asphalt road of 4 km. which is separated from 12th km. of Gumushane-Trabzon highway northwards. Some facilities such as a country café and resting places which the visitors can meet all their needs are present nearby the cave.

Properties


In the area lying between Gumushane and Toruls, upper-crustacean formations have been extensively scattered out. These consist of andezitic and basaltic lavas, tufs and agglomerates in general. Total thickness of this line reaches 1000 m. and intermediary additives changing between 100 m. and 200 m. of thickness and consisting of limestone, marn and gres in places, draw attention. Karaca Cave developed among the massive limestone with abundant cracks, which is surrounded by the vulcanite, in this line.

The cave which displayed development horizontally is composed of four separate elliptic saloons connecting with each other and lies on a horizontal way having four different halls connecting each other. The two of these saloons were divided into two by the wall dripstones which the waters leaking from the crack systems formed and the number of the saloons had increased to six. The walls between the saloons are made up of domestic rocks, not of dripstone pillars. The entrance of the cave has a height of a man, but it widens conically towards the inside. Starting with the entry point to the very end point Karaca Cave has 150 m. of height, 18 m. of average ceiling height and 1500 m2 interior area.

Inside of the cave is rich of the dripstone accumulations and formations. These formations look rather vivid and charming. Their development is still continuing. These dripstones have various colors and forms. Another group of forms drawing attention are cave roses, calsit crystals eccentrics. It is possible to find all sorts of dripstone formations. Stalagmite, stalactite, pillar, organ patterned walls, flag shapes and drapery dripstones, cave flowers, cave pearls, elephant ears, travertine pools, travertine stairs and cave roses were formed on the small stalagmites from dripstone pools. Karaca Cave is a dry cave. But the waters leaking from ceiling and walls formed large ponds on the floor of the cave. The depth of the lakes particularly in the last section of the cave reaches 1 m.

The dripstone formations that exist intensively and abundantly in the cave and their mysterious appearances enchant the watchers. The existence of travertine in various colors from white to dark blue shows that the melted mineral substances are dense in the water which forms the travertine.

There is a river inside the Karaca Cave. However, the waters leaking from the cracks on the ceiling enable the dripstone formation to continue, even today. Also, there are travertine pools and a few ponds inside the cave. The ponds in the entries of second and third saloons are wealthy of water. There is no certain air circulation. Therefore, the humidity rate of the cave air so long as you proceed from mouth towards the inside a relative increase is sensed. According to the measures the humidity increase rate is 65% in mouth, in saloon 1/a 70% and in saloon 1/b 75%. The climate inside the cave is cool in respect to the outside in summer time, and it is a little bit hotter than outside in winter. It is considered that the cave is a little microclimate region with these properties.
