卡尔斯巴德洞窟国家公园位于美国西部的新墨西哥州佩科斯河西岸的吉娃娃森林内部。1930年5月14日建成,面积189平方公里,公园包括83个独立的洞穴。这是一个神奇的洞穴世界,它以丰富多样而美丽的矿物质而著称。特别是龙舌兰洞穴,构成了一个地下的实验室,在这里可以研究地质变迁的真实过程。卡尔斯巴德洞穴形成于2.8亿~2.25亿年前的二叠纪。雨水渗入瓜达卢佩山石灰岩山体的裂缝,溶解了松软的岩石,刻凿出隧洞和洞穴,留下的矿物质形成了各种造型。溶洞分为三层,洞穴中的钟乳石千姿百态,每一处钟乳石都有形象的名字,如“恶魔之泉”、“国王宫殿”、“太阳神殿”等。另外,洞穴中还有岩帷幕和洞穴珍珠。最吸引人的是巨室洞穴,1200米长,188米宽,85米高。四壁的钟乳幔将其装点得犹如一座豪华的宫殿。洞窟内还有另一壮观景象,黄昏时蝙蝠倾巢出动,形成漫天飞舞的“蝙蝠云”。园内还有各种小哺乳动物、爬虫和鸟类等。
