Karstik Landforms have been used differently by the time human being at the historic of each quarter. These shapes which are enclosed tree edge have been used for very long times; house, sanctuary, store etc. Nowadays, these more depth and outlet part limited shapes have been used differently; in terms of named “Orbuk”. Orbuk word which is used in the Mersin Province; Tarsus, Silifke and Partly Adana Regions on the Bolkar Mountains is especially used by nomadic people. Although meaning of Orbuk is reminiscent of “Obruk”, it has very different features of using and constitution. Orbuk word is known all of region people whom they have sustained both transhumance activities in the past-now and settled people. Orbuk is a location which has used to protect and accumulated productions of animal origin which is like cheese, animal fat and curd from hot weather conditions. Orbuk is that may be karstic landforms like as cave, sinkhole, collapse doline or manmade hellhole in the ofiolitic rocks. The feature that comes to the foreground here is not the shape but the "natural cold storage" feature of the products. When the hot is 20-25ºC from the outside, it has approximately 1 – 5 ºC hot. In this study purpose aims that to introduce both meaning and distribution of Orbuks on the Bolkar Mountains. Orbuks are interesting in terms of using actually. These areas are not said about orbuks, because there is a lot of production of animal origin. Because of this, all of orbuk is not disclosed on the map. In this study, some orbuks have been discussed to introduce. After the study, orbuks were classified and six kind of orbuks have been identified in the Bolkar Mountains Orbuk; In Bolkar Mountains, it is the name given to the place where the locals keep products such as milk, cheese, butter and sediment from the animal products they produce in summer. In other words, it can be defined as the natural "Cold Air Store" or "Ice house" places in these areas. The word orbuk is often confused with the word “Obruk”. The Obruks (jamas, avens) are also used as orbuk in this region. Orbuk is a functional term (or using). The orbuks are common places of transhumances (nomadic people) in the Bolkar Mountains. In addition to this, they are also used the snow inside to serve guests from the bowls. These areas are the most natural places where snow is protected from melting, and they mostly correspond to karstic shapes. The orbuks are almost all karstic landforms. These are mostly: collapsing sinkhole (doline), melting sinkhole (doline), obruk (jame), landform, cave, natural depressions. Besides these natural formations, there are also small depressions which can be covered by people's own hands (manmade). In this study, trip – observation method is used. In the duration of field trip questioner was done with nomadic people. Maps are composed with ArcMAP 10.2.2 packet program. Various measurements were made with laser meter and thermometer in the Orbuks. Field trips were performed by together nomadic people which live in this plateau. Findings Orbuk is a new word in the geography in terms of land use. It is used in the Mersin and Near Surroundings. Kind of Orbuks in terms of nascence, there are six styles Orbuks. Collapsed Doline (Sinkhole) Orbuks: The slopes of these orbuks are quite steep and the base is relatively wide. It is a structure that prevents sun rays from reaching the lower part. For this reason, collapses are the most commonly used orbuks. Solution Doline Orbuks: Dissolution Dolines are usually formed in horizontal or near-horizon limestone layers, sometimes in folded formations, in the slightly advanced stage of karstification during the youth phase, as a result of extensions of vertical or convex cracks. Because of the lack of solar rays on the bottom of the steep slope Dolines, these narrow space solution dolines are used as orbuk. On the other hand, these orbuks are not used more commanly than collapsed dolines. Sinkhol Orbuks: Sinkhol is a karstic landform found on the bottom or edge of a closed basin or pit, such as doline, uvala and polje, which drains the waters in the ground. It is also the connection point of the underground windows, surface and underground drainage of underground voids. Mostly in semi-arid areas these areas are quite cool enclosed areas during periods when surface flow is interrupted. Many of the dialects, which have a very narrow entrance, are used as the mouth part of the mouth. Such orbuks are called "bottomless" if they are very depth. Sinkhole Orbuks are preferred to use as orbuks. Open Pit (Jama, Aven) Orbuks; One of the very characteristic landforms of the Karst topography is the pit which shows a chimney or well view. Jama, aven in terms of this feature explained karstik cavities in our country is called obruk. Orbuks are similar to a collapsed doline and are usually connected to a large underground cave system, like them. These shapes are used orbuks in the Bolkar Mountains. Inside of these are very cold. Some of them have Ice inside of these orbuks. There are a lot of these orbuks on the Bolkar Mountains. Cave Orbuks; Caves are the most important karstic landforms that are used and evaluated most in human landforms in karstic formations. In many places their entrance is rather narrow and the interior is too large to compare, causing a different cave atmosphere inside the caves. With this aspect, caves vary in terms of health tourism as well as other usage activities. Generally, caves with cold or mild weather conditions are used as orbuk. Some rock bushes or the fronts of the pines are used by the people as a result of wall constructions narrowing the result further. There are numerous cave orbuks on the Bolkar Mountains. Even when there was no electricity, there were one or two orbuks even in permanent settlements. Alaiye Orbuk is a sample of hundreds Orbuks in the study area. Manmade Orbuks: In Bolkar Mountains, there are also orbuks they have done with their own hands
