没有任何限制(The sky is the limit)

欢迎来到美国亚利桑那州的仙人掌国家公园。今天的照片中，瓦森峰上空出现了一道彩虹，瓦森山是图森山脉的最高点，海拔1400多米。徒步旅行者可以通过King Canyon、Hugh Norris或Sweetwater等小径到达山顶，所有小径都蜿蜒穿过高耸的仙人掌、仙人掌和沙漠野花。在公园的顶部，图森盆地、圣卡塔利娜和林康山脉一直延伸到地平线，使攀登每一步都值得一试。这座山峰以19世纪美国记者约翰·沃森的名字命名，还保留着霍霍坎人和亚利桑那州采矿历史的痕迹，包括古尔德矿。无论你是来这里欣赏风景、历史还是挑战，瓦森峰都是一次真正的沙漠探险——只是不要低估亚利桑那州的太阳！

Welcome to Saguaro National Park in Arizona, United States. Today's image features a rainbow over Wasson Peak, which is the tallest point in the Tucson Mountains at more than 1,400 metres. Hikers can reach the summit via trails like King Canyon, Hugh Norris or Sweetwater, all winding through towering saguaros, prickly pear cacti and desert wildflowers. At the top of the park, the Tucson Basin, Santa Catalina and Rincon Mountains stretch into the horizon, making the climb worth every step. Named after John Wasson, a 19th-century American journalist, the peak also holds traces of the Hohokam people and Arizona's mining past, including the Gould Mine. Whether you're here for the views, history, or challenge, Wasson Peak is a true desert adventure—just don't underestimate the Arizona sun!
