Lake Itasca is a small glacial lake, approximately 1.8 square miles (4.7 km²) in area, in the Lake District of Northwestern Minnesota in the United States. It is the source[1] of the Mississippi River. The lake is located in southeastern Clearwater County within Itasca State Park. It has an average depth of 20-35 feet (6-11 m), and is 1,475 ft (450 m) above sea level.
The Mississippi River starts its 2,340 mi (3,770 km) journey to the Gulf of Mexico at the lake; however, as with most rivers, the exact point cannot be located because there are many small tributaries and marshy areas that drain into the Mississippi watershed. Henry Schoolcraft identified Lake Itasca as the river's source in 1832. He had been part of a previous expedition in 1820 led by General Lewis Cass that had named nearby Cass Lake (which is downstream from Itasca) as the source of the river. The Ojibwe name for "Lake Itasca" was Omashkoozo-zaaga'igan (Elk Lake)[2]; this was changed by Schoolcraft to "Itasca"[4], coined from a combination of the Latin words veritas ("truth") and caput ("head").[3][4] It is one of several examples of pseudo-Indian place names created by Schoolcraft.
The channel of the Mississippi as it emerges from the lake was moved in the 1930s by the Civilian Conservation Corps, as part of a project to create a more pleasant experience for visitors. The project included the draining of the surrounding swamp, the digging of a new channel, and the installation of a man-made rock rapids. Wading across the rapids in bare feet – thus actually walking across the Mississippi River – is a popular recreational activity for summer tourists.
The western arm of the lake is fed by two small streams on its south end. Nicolett Creek, which is considered too small to be considered as the headwaters, starts in a nearby spring. Another small stream leads into Itasca from Elk Lake, which in turn is fed by two other streams. The Ojibwa called Elk Lake and the stream Bekegamaag-zaaga'igan and Bekegamaag-ziibi (Sidelake Lake and Sidelake River), respectively.[2] In 1887 Williard Glazier promoted a campaign to consider Elk Lake, which he called Glazier Lake, as the true source of the Mississippi. These streams, however, are generally considered too small to be categorized as the headwaters of the river.
The decision was made by Jacob V. Brower, a land surveyor and president of the Minnesota Historical Society, who after spending five months exploring the lakes ruled that the lakes and streams further south of Lake Itasca were not the true source of the Mississippi. Brower was to campaign aggressively to save the lake from logging. On April 21, 1891, the Minnesota Legislature officially made it a state park by a margin of one vote. Brower is now called the "Father of Lake Itasca" and the visitor center is named in his honor.
The lake is home to the University of Minnesota's Biological and Forestry Campus that is open year round. It hosts cabins for the students and faculty, laboratories, and an extensive library. Classes are offered in the summer semester. Because of this, Lake Itasca and environs are heavily researched and very well studied. The current head of the biological station is Dr. John Biesbor.
When it was founded the Lake Itasca region was able to boast that it was the juncture of the three great habitats of North America. The Great Plains, the Deciduous Forest of the south and the Coniferous Forest of the north. To this day remnants of all three may be observed in the park.
Interestingly, the unique geography of the Lake Itasca region has even found its way onto the classical music concert stage. Composer Ferde Grofe depicted the birthplace of the Mississippi River and the Native Americans who reside there in his popular classical epic the Mississippi Suite .
