A river on the tundra

This mesmerizing expanse captures a small stretch of the 95-mile-long Ivishak River in northern Alaska. The Ivishak flows in the Philip Smith Mountains and the foothills of the Arctic National Wildlife Refuge. The entire run of the river is in a region called the North Slope Borough, Alaska's northernmost borough (Alaska is divided into boroughs, not counties). Look at the magnificent colors and textures this photo captures—it's a view that's preserved and protected by the Wild and Scenic Rivers Act.

The act was signed into law on October 2, 1968. The main purpose of the bill was to identify 'certain selected rivers of the [US] which, with their immediate environments, possess outstandingly remarkable scenic, recreational, geologic, fish and wildlife, historic, cultural or other similar values, shall be preserved in free-flowing condition…' Sure, we could have summed it up for you, but instead quoted the exact text from the Wild and Scenic Rivers Act to show how all-encompassing the intent of the protection is.

冻土带上的河流

这片迷人的广袤土地捕捉到了阿拉斯加北部95英里长的伊维沙克河的一小段。Ivishak河流经菲利普史密斯山脉和北极国家野生动物保护区的山麓。整条河流都在一个叫做北坡区（North Slope Bourough）的区域内，这是阿拉斯加最北端的一个自治区（阿拉斯加分为自治区，而不是县）。看看这张照片捕捉到的壮丽色彩和纹理，这是一幅受《野生和风景河流法》保护的风景画。

该法案于1968年10月2日签署成为法律。该法案的主要目的是确定“某些选定的[美国]河流及其周围环境，具有显著的风景、娱乐、地质、鱼类和野生动物、历史、文化或其他类似价值，应在自由流动的条件下予以保护……”当然，我们可以为您总结一下，而是引用了《野生和风景河流法》的确切文本，以表明保护的意图是多么全面。
