Most of the nearly five million people who visit Grand Canyon National Park each year simply take in the stunning views from the rim. The more adventurous descend the canyon and get up close to rock that dates back 1.8 billion years. Here, hikers traverse Deer Creek Trail, an overnight trip that’s one of the most popular routes in the park.
每年都有将近5百万游客来到大峡谷国家公园，大多数人都只去了它的南缘欣赏其迷人的景观。更冒险的是下到峡谷底，近距离接触这些岩石，可以追溯到18亿年前。图中，背包客们穿过鹿溪径，连夜赶路，这是公园里最受欢迎的游玩路线。
