Lake Itasca Facts

The deceptively simple term of Lake Itasca serves as the most frequently used common name for this lesser-known marvel of Nature. That’s the english language appellation for the lake, though. Ancient Indigenous Peoples of the region had other names for it.
The local Ojibwe People, along with other native groups, long knew of its existence, of course. The name they applied to the remarkably beautiful lake was Omashkoozo-zaaga’igan. Loosely translated into english the moniker meant Elk Lake.
Among non-native individuals, historians aren’t completely certain who spotted it first. Though opinions vary, the majority of experts believe that fur trader William Morrison holds that distinction. He sighted it sometime between 1803 and 1804.
No matter who saw it first, or when, the formation holds a surprising importance in the region in which it lies. That’s because, despite its unassuming appearance, it technically qualifies as the source of the headwaters of the mighty Mississippi River itself!
Its beauty and importance earns the stunning Lake Itasca its own appreciation. It now serves as the central feature of the aptly-named Itasca State park. This fortunately provides it with a certain amount of protection from the depredations of man.

Lake Itasca Physical Description

The natural beauty of Lake Itasca quickly captivates those fortunate enough to visit the site. Yet, unlike some similar features, it does not do so due to its physical dimensions. That’s due to the surprising fact that, regardless of its importance, it’s relatively small.

It stands out from most such bodies of water in regards to its general shape, as well. The same geological forces that created it also gave it something of a T-shape structure. That section that constitutes the cap of the letter-shape distinctively tilts slightly to the left.

Its total surface area only measures a mere 1.8 sq mi (4.7 sq km). Despite the tiny surface area of the lake, its extraordinarily irregular outline still provides it with at least one respectable dimension. Impressively, it manages to boast a total shoreline of 14.3 mi (23 km).

Regardless of other facctors, the gorgeous Lake Itasca nevertheless manages to amaze many people due to another characteristic. That pertains to its depth. The body remains quite shallow in nature. Its depth varies greatly because of changes in its own source.

As a general principle, though, that particular aspect measures between a mere 20 – 35 ft (6.1 – 10.7 m). At its deepest recorded section, though, its maximum depth has never exceed 40 ft (12.2 m). Nature, however, has never associated size with impressiveness.

Lake Itasca Location, Formation, and Geography

The magnificent Lake Itasca formed in a region of the globe already renowned for its abundance of geological wonders. That precise region won’t surprise the people who know of the Mississippi River, though. It lies within the confines of the United States.

Therefore situated on the continent of North America, the lake resides in the state of Minnesota. That itself sits in what’s considered the Upper Midwest section of the country. Its exact geographical location further places it in the general northwestern part of the state.

This small but disproportionately vital body of water itself owes its own formation to a special set of circumstances. The nature of those also explain why its depth varies so much, as mentioned above. That’s because this marvel’s what’s known as a glacial lake.

During the last ice age, retreating glaciers carved out the basin where it sits. Following that, numerous naturally occuring springs provided roughly half the water to fill it. The remainder comes from rainfall. Since this varies, it accounts for the widely differing depths.

Even though amazing Lake Itasca is small, it plays yet another important role. Its location coincidentally places it at the convergence of an astounding three distinct ecosystems. These consist of regions of eastern deciduous forest, tall grass prairie, and coniferous forest.

Both flora and fauna common to all three types of region appear at and around the site. Along with the grasses and trees, some of the plants present even include wild rice! Animals found here include deer, beaver, porcupines, black bears, wolves, and countless birds.
