Its longest tributary originates at Little Elk Lake, which is 100 ft (30 m) higher in elevation and 11 km upstream from the Lake Itasca outflow, at and in the Mississippi watershed.

Some of these buildings date from the 1930s and 40s, while others, including the largest building the Biome Center, were built more recently. The current Director of the biological station is Jonathan Schilling. The Lake Itasca region claims a unique location, not only at the headwaters of the Mississippi River and amidst 25% of the old growth forest of Minnesota, but also at 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. Remnants of all three may be observed in the park. The unique geography of the Lake Itasca region has found its way onto the classical music concert stage.
