The classification methods of mountains and mountainous areas are based on the combination of parameters composed according to the morphological features of the mountains. Although the most distinctive features that distinguish a mountain from other morphological units are elevation and slope, these features are often not sufficient to define mountains. Therefore, there is no definite definition of where the border of a mountain passes. Separating the mountains as a morphological unit from other units is necessary for the continuation of vital activities within mountains and their area of influence. In this respect, it is important to reveal the boundaries of mountains and mountainous areas. The aim of this study is to compare the main parameters used in classifications describing macro landforms to determine the mountain boundaries and to discuss which parameter is more effective. In this context, it is aimed to determine the most suitable morphological features to specify the mountain boundaries in this study. For this purpose, parameters used in landform classification were analysed and commonly used parameters such as elevation, slope, local elevation range, surface curvature, standard deviation of elevation, standard deviation of slope, gentle slope, roughness were applied to the specified field, which is Erciyes volcanic mountain (3917 m) located in Central Anatolia. These analyses were carried out through 25 m resolution Digital Elevation Model over Europe and 90 m Multi-Error-Removed Improved –Terrain DEM data using ArcMap 10.6 program. The analyses regarding the mountain boundary were supported by field studies. Discussions and suggestions are presented about which parameters give the most accurate results in determining the mountain boundary. The results show that different combinations of parameters are more functional in different areas due to the genetic characteristics of the mountains and the environmental geomorphological structure.
