The Hida mountain range, which has a maximum height of more than 3000 meters, lying in the northern part of the Japan Alps, con-sists chiefly of gneiss, granite, quartz porphyry, and andesite. The 1100 points that are used in triangulation survey are availed of in this newly projected profile. According to the new method, the mountain range is devided into a number of zones, each 20km wide (Fig. 3). Points lying in one zone are projected on a plane that is vertical to it, and the profile is drawn by connecting the high points amomg them. (Fig 1). This is the newly projected profile, according to which, the Hida mountain range may be described as follows.
1. Its northern part is a warped block.
2. Its southern part is also a warped block, although its eastern side is cutt off by faulting.
