当金山所在的阿克塞哈萨克族自治县位于甘肃，青海，新疆三省（区）交界处，东至燕丹与肃北县接壤，北依催木图山与敦煌市为邻，南面的赛什腾山与青海省毗连，西面的芨芨台与新疆维吾尔自治区的戈壁相望，总面积3.3万平方公里。昔日属于人迹罕至，飞鸟不驻之地。当金山位于祁连山于阿尔金山的结合部位，山脉呈东西向展布于肃北之南。层峦叠嶂，山势陡峻，植被稀疏，纵横沟谷切割剧烈，山体南北两侧宽度一般25～35km，沟谷大多呈“V”字形，沟谷两侧自然山坡坡度在30°～60°之间，当金山北坡陡峻，南坡相对平缓，地表风化严重，岩体破碎。由于受东西向断层的影响，山间东西向断陷盆地较发育，且地形开阔，盆地断面呈“U”字形宽谷，谷底高程一般在2800m～3600m。地面高程一般在2800m～3700m之间，相对高差500～1000m
