纳瓦霍国家纪念碑位于该州的东北角，位于黑梅萨附近，创建于1909年，用于保护在公元1250至1300年间建造的三座大型普韦布洛遗址，名为Keet Seel，Betatakin和Inscription House。这些房屋建在岩壁上的大型天然壁龛内，是祖先普韦布洛人的家园，他们养殖了峡谷的溪流梯田。除了大型的普韦布洛村庄外，考古证据还记载了过去几千年来人类对该地区的使用情况。狩猎采集者首先生活在这些峡谷中，然后是大约2000年前的篮子人，然后是祖先的普韦布洛人，他们猎杀野生动物并种植玉米，豆类和南瓜。从居民那里下来的现代部落包括霍皮人，纳瓦霍人，圣胡安南部派尤特人和祖尼人，公园周围是纳瓦霍族，他们在这里生活了数百年。 Organ Pipe Cactus国家纪念碑位于亚利桑那州与墨西哥索诺拉州之间的边界，位于Ajo附近，是一座国际生物圈保护区，成立于1976年，研究和保护索诺兰沙漠中发现的非凡植物和动物。从这里可以找到31种不同种类的仙人掌，从巨型柱仙人掌到微型枕形，高度发达，在干旱环境中茁壮成长。仙人掌全年开花，有各种黄色，红色，白色和粉红色;在春天，金墨西哥罂粟花，蓝色羽扇豆和粉红色猫头鹰三叶草增添了显示效果。管风琴仙人掌生活超过150年，仅在第35年晚上开放白色奶油花。在公园里发现的动物包括Sonoran pronghorn羚羊，沙漠大角羊，山狮和蝙蝠。在公园里发现了大约270种鸟类，但只有36种是永久居民，包括哥斯达黎加的蜂鸟，仙人掌，曲线鲸鱼和吉拉啄木鸟。
The Navajo National Monument is located in the northeast corner of the state, near the Black Mesa. It was founded in 1909 to protect the three large Pueblo ruins built between 1250 and 1300, called Keet Seel, Betatakin and Inscription House. Built in large natural niches on the rock walls, these houses are home to the ancestors of the Pueblo people who farmed the canyon’s stream terraces. In addition to the large village of Pueblo, archaeological evidence also documents the use of humans in the region over the past few thousand years. The hunter-gatherers first lived in these gorges, then the baskets of people about 2,000 years ago, and then the ancestors of the Pueblo, who hunted wild animals and planted corn, beans and pumpkins. Modern tribes from the inhabitants include Hopi, Navajo, Paiute and Zuni in southern San Juan, surrounded by Navajo, who lived here for hundreds of years. The Organ Pipe Cactus National Monument is located on the border between Arizona and Sonora, Mexico, near Ajo. It is an international biosphere reserve established in 1976 to study and protect the extraordinary plants and animals found in the Sonoran Desert. From here you can find 31 different kinds of cacti, from giant saguaro to miniature pillow, highly developed and thriving in arid environments. Cactus blooms throughout the year, with a variety of yellow, red, white and pink; in the spring, golden Mexican poppies, blue lupines and pink owl clover add to the display. The organ organ cactus has lived for more than 150 years and only opened white cream flowers in the 35th night. Animals found in the park include the Sonoran pronghorn antelope, the desert bighorn sheep, the mountain lion and the bat. About 270 species of birds were found in the park, but only 36 were permanent residents, including Costa Rican hummingbirds, cacti, curvy whales and Gila woodpeckers.
