The Chahkuh Strait is located in the geographical location N264057 E553216 in the province of Hormozgan and east of Qeshm Island. The valley or Strait of Chahkuh, in the Shahab district of Qeshm, a valley at a depth of 100 meters, is a demonstration of the erosion of sedimentary rocks. This valley is located 70 km from Qeshm, along with the village of Chahi East, in the western part of the north coast of Qeshm, and is one of the most important tourist attractions in Qeshm. This amazing valley is located at the heart of a complex rocky stone that is cut in crossed form. The well is initially widespread and with long walls facing the eyes of the audience, but gradually narrowing it to the point where it is difficult to cross it, while the height of the walls remains high and therefore inside There is little light valley.
The reason for naming Chahkuh is the existence of roads drilled at the beginning of the valley, a few shallow wells and canals for water guidance, dug from the village of Chahu, and double the beauty of the Strait. Because of the warm and susceptible nature of the area, the freshwater stored is of high value, these wells are a rainwater storage site. These canals and wells are ancient in nature, and from ancient times, freshwater reservoirs from this part of the island Has been used.
The valley is of foursquare, with four walls, where the walls come together and the distance between two walls may reach about half a meter. It seems that the valley and similar valleys around it are related to the great azathar fractures that also played a role in the formation of salt domes. The genus of wells is composed of sedimentary rocks, called limestone rocks, belonging to the Zagros Mountain range, which is one of the three groups of rocks in nature (sedimentary, igneous and metamorphic). In the walls of the Chahche Valley, water erosion and dissolution have been excavated deep and long grooves and various lens, spherical and spherical cavities. The presence of parallel grooves and lines, as well as the hole and the niche on the perpendicular body of the valley, as well as the presence of rocky deposits in the valley floor, have made the Chaghcho to become a miracle. Patterns and shapes that affect the walls of this Strait will affect the roles of each viewer. Fantastic and dreamlike forms, such as valuable works of art, created by the artist.
Wind, rainwater and floody and severe rainfall are one of the most important reasons for the presence of these large holes in the well-wall. Wells have lime or calcium bicarbonate, which causes rain water acid to dissolve them and create small gaps and holes within them, and these cavities have become larger over the course of a few million years and have become an interesting hole. . Meanwhile, water flooding during the rain, doubles the beauty of this valley.
The entrance to the north-south valley is wider and more sloping from the north, and it shows a more orthodox shape. As far as the south, the valley is wider. The slope increases and ends up in the form of V and becomes sluggish. These specifications indicate valley flood. The valley walls of the grooves and lines of erosion show a number of parallels, which sometimes find these grooves more deeply and take spongiform or capillary forms. The walls of the walls are mainly limestone sandstone and because of the presence of red marl, silt and limestone layers, there are dissolution and severe erosion in these parts, so that in the whole length of the walls of the valley there are numerous small and large cavities are. It seems that the shallow wells that are used by the people are drilled by hand, but this drilling has been followed by deep dissolution cavities and in fact the work of nature has been completed by mankind. Also, along the main valley and perpendicular to the valley there is a barricoid canal, apparently drilled into the well to guide the valley water. Due to the relatively high vertical walls, there are parallel and deep erosion grooves and lines, as well as semi-spherical and elliptical cavities of particular beauty.
Chahkuh Strait is one of the attractions of Qeshm Geopark, and so far there have been some measures approved by UNESCO in the Strait. Construction of a 4 km long road, construction of a health service, installation of educational and environmental guides, installation of garbage bins, construction of parking and installation of guard kiosks are among the activities of Qeshm Free Zone Organization in this Strait of Tourism.
