切木尔切克古墓群切木尔切克古墓群，距阿勒泰市约30公里，距切木切克乡集镇15公里，位于平坦戈壁向山区过度地带，数约有100余琢，分布在约5平方公里范围内。墓有大、有小，有的较集中，有的分散。较大的一座长约65米，宽35米，位于哈底那尔村西，平均海平面高764米，墓前立有高1.5米，宽60公分，厚400 公分，4块巨大黑石石碑，上刻有凸形浮雕头像， 较小的墓大多分散在起伏土丘的制高点，墓前大多有一块立石，四周大多铺成直植的块石围护，隆起略高于地平面。1963年新疆社会科学院考古研究所，有计划进行了部分发掘，发现墓葬形式有墓院制和单墓制两种，墓院制地表大多无封土，周缘多有列石围护，单墓制四周无列石围护。但两种墓葬都又分为石棺和竖穴土坑，石棺表面有的有封土，有的没有，竖穴土坑均有封土，埋葬方式为：屈肢、仰身直肢、俯身直肢和乱首葬。出土文物有石器、陶器、铜器、铁器、骨首质器等，时代起于战国延伸至突厥时期，近千年。墓区除古墓以处，还有左文字石刻，岩画，这些可能是此方草原上的游牧民族匈奴、突厥等民族的遗迹。考古学界有人将切木尔切克墓葬称为切木尔克文化，可见地位之高。
