The Flood that Reshaped Southern Idaho
The Snake River Canyon is one of Idaho's most recognizable geologic features. Volcanic forces dating back more than 10 million years ago created the canyon. But it took the second largest flood in the history of the world to reshape it and to give the canyon its unique appearance as we see it today.

|In 1811 the Hunt party likened the terrific torrent of the Snake River three miles east of here to a boiling caldron, adding the the old Scottish word "linn," meaning a waterfall. They had lost a man and a canoe in a roaring chute upstream. Finding worse water ahead they abandoned river travel. Next year, another explorer said of Caldron Linn, "Its terrific appearance beggars all description." Today no road reaches the spot and the name is forgotten. — Map (db m31523) HM|

Now the waters upstream have been harnessed for irrigation and power, and in the dry summer months the rocks can be seen. But the foaming river and the sheer walls of the canyon combine with the paths and shady lawns of the park and picnic area to make one of Idaho's most spectacular scenes.

|Indiana (Allen County), Fort Wayne — First Americans|
|The confluence area of the Three Rivers was known to the native people since as early as the end of the last Ice Age, more than 10,000 years ago. As the glaciers melted and receded, they paused here creating a high point in the topography of the land. Early native people followed the edge of the glacier taking advantage of the food sources it provided, such as vegetation and wild game.

2. Fill the hole with glacial meltwater. Stir your brand new lake with strong prevailing northwest winds.
3. Find the grains of sand needed for your dunes that are mixed within the ridges. The challenge is to sort the sand from all the clay, pebbles, and rocks.
4. Use wind-whipped waves to erode the ridges and sort out the grains of sand. (The . . . — Map (db m61673) HM|

History of the River
The Wabash Valley drained thousands of square miles of the Wisconsin glacier during the latter part of the Ice Age, acting as the primary sluiceway for unimaginably large amounts of glacial meltwater that would dwarf the modern river modern times over. Vast amounts of glacial outwash composed of coarse sand and gravel were deposited in the sluiceway, eventually filling it from rim to rim. The event most directly responsible for the form and size of the modern . . . — Map (db m68095)|

Although it has the appearance of a valley, it is entirely surrounded by higher ground. Like several other smaller sinks in this section of Kansas, Big Basin was formed thousands of years ago by the dissolving and collapse of massive gypsum and salt formations lying several hundred feet below the surface.
