Howz-Māhy is a region located in the center of Iran, where a considerable number of petroglyphs can be found in two sites, at Ghārā-Tepe I and II. Ghārā-Tepe I is the largest site and includes a variety of depictions, especially geometric markings. In addition, various depictions can be found throughout the region situated on isolated cliffs and stones on the edge of an ancient pool. The most common image is of ibexes. There are also several other kinds of representations that show animals, humans, geometric markings, and so on, which can be found on panels. Despite difficulties for dating the petroglyphs of Iran, microerosion analysis should be applicable for dating the engravings of Howz-Māhy, especially in Ghārā-Tepe I.
