超级沙甜16

我们在科罗拉多州南部的落基山脉庆祝大沙丘国家公园，并将其作为一个完整的国家公园保护了16年，尽管它是1932年的国家纪念碑，沙丘本身和周围山谷的历史都要古老得多。

We're in the Rockies of southern Colorado to celebrate Great Sand Dunes National Park and Preserve's 16th year as a full-fledged national park—though it was a national monument from 1932, and both the dunes themselves and the surrounding valley's history are far more ancient.
