In 1854, the United States took the mineral-rich lands of northeastern Minnesota Territory from the Ojibwe Nation after the signing of the Treaty of La Pointe. Four years later, it granted to the new state of Minnesota sections 16 and 36 of every one of its townships, either to be held in trust or leased to support state schools. Close to three million acres were dedicated to a public school trust fund, and the iron ore and forest lands of the Ojibwe generated over 85 percent of its value. In 2017, it is worth over a billion dollars.

Gouverneur Kemble Warren, topographer, Civil War veteran, and accomplished engineer, served his entire career with the U.S. Army. During his service, he mapped the tributaries of the Mississippi River and transcontinental railroad routes. As the first district engineer in St. Paul, he worked to preserve St. Anthony Falls and designed the nation’s first reservoir system. Glacial River Warren, which carved the Pleistocene channel now followed by the Minnesota River, is named for him.
