Where the Water Flows: Understanding Glacier’s Triple Divide Peak

Imagine pouring out a glass of water. Where does the water go?

After soaking your computer or floor, it would eventually flow to join a greater body of water and become part of a larger drainage system. Where I grew up, outside of Milwaukee, my water would join with Lake Michigan. In the Twin Cities, where I went to university, it would flow into the Mississippi River. From Jackson, Wyoming, where I’m writing now, it would combine with the Snake River and flow into the Pacific Ocean. But Glacier National Park, where I worked in the summer of 2017, has a unique little point called Triple Divide Peak.

Why is water sacred to Native Americans?

The Lakota phrase “Mní wičhóni,” or “Water is life,” has become a new national protest anthem. It was chanted by 5,000 marchers at the Native Nations March in Washington, D.C. on March 10, and during hundreds of protests across the United States in the last year. “Mní wičhóni” became the anthem of the almost year-long struggle to stop the building of the Dakota Access Pipeline under the Missouri River in North Dakota.

Mapping Ocean Currents

How can a map visualize a water current—something that is powerful and physically palpable, but that lies beneath the surface and is largely invisible to the eye? In a recent map, scientists at the National Aeronautics and Space Administration (NASA) represented the course of the Gulf Stream in the Atlantic Ocean through swirls of vibrant color denoting its thermal temperature…

At What Point Do We Protect Rivers? by Megan Boian of American Rivers

At What Point Do We Protect Rivers?

One of the biggest policy debates currently involving rivers is over the proposed federal Clean Water Rule. As this blog from American Rivers explains, the Clean Water Rule clarifies which waters in the United States are protected by the Clean Water Act. The Clean Water Act, the federal government’s primary regulatory tool against water pollution, stipulates which waters should be monitored and improved with the goal of becoming fishable, swimmable, and drinkable. The proposed Clean Water Rule draws on extensive review of scientific literature to clarify the ultimate connectivity of major rivers to other sources of surface and ground water.
