Mountains are rightfully considered the highest, beautiful and majestic phenomena of nature. Mountain Dena is located in the southeastern part of the ridge, and is one of the highest peaks of this mountain range.
Covered with snowy hats, durable glacier and magnificent mountain rivers of this area not only create violent vegetation, but also represent an environmental range for many animal species. Due to the existence of an unmatched ecosystem in this area and the need for its preservation by decision of the Supreme Council of Environmental Protection of Iran, part of the ridge Pogro was recognized in 1990 "Reserve Dena", And after 10 years, the other parts of this area entered this reserve.
Dena has long attracted climbers who went to this area from all the ends of Iran and even from different parts of the world in the hope of conquer one or several of her peaks.

In general, the Dena Mountain District is delineated by the passage of Biezen in the East, and the two rivers Marbor and Beshar – north, west and south. Marbor flows on the northern border of the Denya from the east to the west, but, by passing the village of Herson, called the Herson River, then passes through the village of Maimand, turns to the south and, passing a narrow and very deep gorge, merges with the Besar River. River Besar flows through the southern border of Mount Dena, also from East to West. At the constituency of two rivers, one of the most important tributaries of the Karun River under the name Herson is formed. Here is a magnificent forest array. The highest point of this area is the peak of Kash Mast. Its height 4435 m from sea level.
From the point of view of natural morphology, the southern front of the Deny has a more or less sheer shape, and its foots are covered with oak groves, which extend far to the north and eastern part of the province of Kohkiluye-Buyer-Ahmad. The North Front is characterized by a dry or semi-dry climate and almost deprived of forest cover.

Above 3500 m large plants are no longer there and the foundation of vegetation is grass and thickets, which in turn disappear at an altitude of more than 4000 m. Sometimes, of course, some separate types of plants can survive in the cracks and crevices of the cliffs, where they do not get cold wind. Summer The slopes of the mountains are covered with a motley carpet of mountain colors and endless meadows.
