Zard Kooh-e-Bakhtiary
Zard Kooh, ZardKooh, Zard-Kooh, Zard Kouh, ZardKouh or Zard-Kouh or the full name Zard Kooh-e-Bakhtiary is not the name of a individual peak but it's one the most great and famous sub ranges of Zagros range, the terms mean "The yellow mountain of Bakhtiarys". (I'll shorten the name to ZK in follow...)
The mountain is located in Chaharmahal-e-Bakhtiary province (The cold season starts October, coldest -15 centigrade  warmest 35.5 centigrade average 10.3 centigrade) near Shahr-e-kord and Koohrang cities, probably one of the most beautiful places of Iran, ZK is the source of two most major rivers of Iran Karoon and Zayandeh-roud of Isfahan.
Chaharmahal-e-Bakhtiary people and nomads are the most nice people, they believe to be the best to the guests... ZK is the warm season source of the Bakhtiary nomads who deal with the hard mountain conditions. They breed sheep and goat and produce the best meat, wool, natural diary products and hand works. Bakhtiary's Kebab is one of the best Iranian foods you can have the original versions in this place.

Most high known peaks
The ZK sub range is made by a long north-west oriented to south-east ridge line with few sub ridges or parallel ridges. The ridge line can be divided into five sections with the following peaks located on each section.
ZK geographical location is 49:30 to 50:20 E and 32:05 to 32:55 N.
Normal routes are easy you will need suitable clothes and boots, tent and other equipments. But for routes marked you will need special equipment such as carbines, crampons, piton, hammer and etc.

E-U-Lack:
The most north part. West to Sheikh-Ali-Khan village, E-U-Lack glacier and Koohrang river valley. The rocky block Haft Tanan is the most impressive and highest peak of this part, having the great wall at west, using the normal route from Koohrang valley still is the easiest peak to climb, the other peaks are not easy and may need some technical climbing. The E-U-Lack is a twin peak !

About Iran and Chaharmahal-e-Bakhtiary

[I added this section to give a small glance to people who want to travel to Iran]
Iran is high plane hosting two vast ranges of mountains Alborz and Zagros including hundreds of 4000+m summits. Even taught there are two big deserts in the middle of Iran still it's been said 3/4 of the plane is covered by mountains, there are still lots of 4000+m and 3000+m outside the Alborz and Zagros ranges scattered all over the Iran plane like Kerman mountains and Taftan volcano, the weather varies from dry hot to mountain conditions and to the thick green lush and humidity of the north Caspian sea coast.
The behavior of Iranians is friendly and they are helpful to foreign people from Europe and America (this friendly behaves may no be applied to Arabs), you can quickly make a friend who would be glad to guide you and stay beside you and invite you to his/her home.
The pipe-supplied and mineral water and food served in restaurants and supplied from stores is safe (avoid food from road sellers in downtown).
Security is granted by the police, there are two kind of polices in Iran the green ones and the blue ones, blue is only for traffic control, greens are for security and criminal matters.
Alcoholic drinks are forbidden in Iran, Christians won't be punished for carrying, anyway most people use drinks in their house and parties illegally and they have their own illegal alcohol suppliers who supply drinks from Iranian native drinks to Russian and western drinks, if you needed drinks you can easily find it illegally.
