石门关

游览区位于苍山西坡南部，最低海拔约1700米，有石门关、七道水瀑布、玉皇阁和万亩核桃园等著名景点。在陆内造山运动作用下，苍山不断隆升，受到巨大的区域构造力的作用，其内部也形成了一系列近东西向的张性破裂带、节理裂隙等，流水沿着这些相对软弱的区域不断扩张和下切，继而造就了“天开石门”、“绝壁观云”等丰富的自然景观。

The tourism area is located in the southern part of the west slope of Mount Cangshan. It has a lowest altitude of 1,700 m and comprises famous attractions such as Shimenguan Pass, Qidaoshui Waterfall, Yuhuang Pavilion and Walnut Ecological Base. Mount Cangshan is continuously uplifted by powerful regional tectonic forces inside the Earth to create a series of nearly east-westward tension fracture segment, joint fissure and other terrains. Streams extend and cut through these relatively weaker areas to form scenic attractions such as the ‘Heavenly-opened Stone Gate’ and ‘Clouds on Cliffs’.
