驯鹿 秋季迁徙时正在游过科伯克河的驯鹿 每年秋天，25万头驯鹿聚集在一起组成了北极西部驯鹿群，这群驯鹿在阿拉斯加西北部进行了史诗般的迁徙。它们从乌图克河高地的产犊地向南迁移到苏厄德半岛的冬季牧场。秋天也是科学家们给牛群成员系上无线电项圈，追踪它们的位置和健康状况，并获得有助于保护该物种的信息的时候。当春天到来时，他们将再次以相反的方式完成旅行，每年总共行驶2000英里拿着。一个观察牛群迁徙的最佳地点之一是在洋葱波蒂奇，成群的动物穿过这条河，科布克河。这个名字来源于因纽特人（Inupiaq，因纽特人），意思是“野洋葱”，意思是这里生长的许多野洋葱。但是当地因纽特人来这里不仅仅是为了寻找洋葱。几千年来，驯鹿穿越吸引了依赖驯鹿肉的原住民，这一传统一直延续至今。

原文:

Each fall a quarter million caribou come together to form the Western Arctic Caribou Herd, a group that makes an epic migration through northwest Alaska. In great numbers they move south from their calving grounds in the Utukok River Uplands to their winter range on the Seward Peninsula. Fall is also the time when scientists attach radio collars to members of the herd, to track their location and health, and to gain information that will help conserve the species. When spring arrives, they'll complete the trip again in reverse, covering a total of 2,000 miles each year, give or take.One of the best spots to see the herd on the move is where the great masses of animals cross this river, the Kobuk, at Onion Portage. The name of the portage derives from an Inupiaq (Inuit) word meaning 'wild onions' for the many wild onions that grow here. But the native Inuit people don't come here just to forage for onions. For millennia, the caribou crossing has drawn native peoples who rely on caribou meat, a tradition that continues to this day.
