Antelope Canyon is a slot canyon in the American Southwest. It is located on Navajo land near Page, Arizona. Antelope Canyon includes two separate, photogenic slot canyon sections, referred to individually as Upper Antelope Canyon or The Crack; and Lower Antelope Canyon or The Corkscrew. The Navajo name for Upper Antelope Canyon is Tsé bighánílíní, which means “the place where water runs through rocks.” Lower Antelope Canyon is Hazdistazí (advertised as “Hasdestwazi” by the Navajo Parks and Recreation Department), or “spiral rock arches.” Both are located within the LeChee Chapter of the Navajo Nation.
Antelope Canyon was formed by erosion of Navajo Sandstone, primarily due to flash flooding and secondarily due to other sub-aerial processes. Rainwater, especially during monsoon season, runs into the extensive basin above the slot canyon sections, picking up speed and sand as it rushes into the narrow passageways. Over time the passageways eroded away, making the corridors deeper and smoothing hard edges in such a way as to form characteristic ‘flowing’ shapes in the rock.
羚羊峡谷（英语：Antelope Canyon、纳瓦荷语：Tsé bighánílíní dóó Hazdistazí），是世界上著名的狭缝型峡谷之一，也是知名的摄影景点。其位于美国亚利桑纳州北方，最靠近的城市为佩吉市，属于纳瓦荷族保护区。羚羊峡谷在地形上分为两个独立的部份，称为上羚羊峡谷（英语：Upper Antelope Canyon）与下羚羊峡谷（英语：Lower Antelope Canyon）。是谁第一次发现羚羊峡谷的记录已不可考。据纳瓦荷族的历史传述，该地过去是叉角羚羊栖息处，峡谷里也常有羚羊漫步，这也是此峡谷名为羚羊峡谷的由来。老一辈的纳瓦荷族曾将此地视为静思与大灵沟通的栖息地。
羚羊峡谷如同其他狭缝型峡谷般，是柔软的砂岩经过百万年的各种侵蚀力所形成。主要是暴洪的侵蚀，其次则是风蚀。该地在季风季节里常出现暴洪流入峡谷中，由于突然暴增的雨量，造成暴洪的流速相当快，加上狭窄通道将河道缩小，因此垂直侵蚀力也相对变大，形成了羚羊峡谷底部的走廊，以及谷壁上坚硬光滑、如同流水般的边缘。 大峡谷的形成并不仅靠科罗拉多河的水流。高原暴雨导致的山洪暴发，才是地表切割最主要的力量。越是干旱的荒山，一旦暴雨，山洪暴发的力量就越是惊人。极度干燥坚硬的地表吸水性很差，降雨顺地势冲刷，如果地表有些许裂隙，湍急的水流和携带着一路冲下的砂石几乎无坚不摧，日积月累，就能将地貌天翻地覆。
