|Idaho (Twin Falls County), Hagerman — 330 — Fishing Falls|
|When John C. Fremont came this way mapping emigrant roads in 1843, he found an important Indian village at Fishing Falls (Kanaka rapids) about 4 miles above here. He reported that native salmon spearers there were "unusually gay...fond of laughter; and in their apparent good nature and merry character...entirely different from the Indians we had been accustomed to see." As Snake River's highest salmon cascades, Fishing Falls was included on many early western maps. — Map (db m31652) HM|
|Idaho (Twin Falls County), Hagerman — 204 — Salmon Falls|
|In 1812, Joseph Miller found 100 lodges of Indians spearing thousands of salmon each afternoon at a cascade below here. Each summer they dried a year's supply. After 1842, they also traded salmon to Oregon Trail emigrants. John C. Fremont marveled at Salmon Falls 18-foot vertical drop, adjacent to "a sheet of foaming water...divided and broken into cateracts" by islands that "give it much picturesque beauty, and make it one of those places that the traveler turns again and again to fix in his memory." — Map (db m31597) HM|
|Idaho (Twin Falls County), Hagerman — 166 — Thousand Springs|
|Old lava flow changed the geologic structure of this area and thus created a multitude of famous springs here. Over thousands of years, volcanic activity repeatedly spread lava over the Snake River plain, slowly forcing the river southward in a great curve. Successive channels of the river and its tributaries were filled with spongy lava, and became both reservoirs and underground conduits gathering water from far to the northeast. Torrents from one or more of these buried channels burst forth on the opposite canyon wall. — Map (db m31595) HM|
|Idaho (Twin Falls County), Hansen — Ancient Lake Bonneville — "Southern Idaho's Largest Flood in World History"|
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.

|Idaho (Twin Falls County), Murtaugh — 284 — Caldron Linn|
|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|
|Idaho (Twin Falls County), Twin Falls — 172 — Shoshone Falls|
|4 miles east of here, the Snake River falls in thunder 210 feet over a rocky ledge higher than famous Niagara. Indians, trappers, and travellers all knew the "Great Shoshonie." 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.

|Around the turn of the century, the nationwide “City Beautiful” movement found local expression through the efforts of Charles Mulford Robinson and nationallly known landscape architect George Kessler. Seeking to reclaim the natural beauty of our rivers, Mr. Kessler incorporated them into a sweeping plan of riverside drives and parks that would bring the Indiana landscape into the heart of the city.

|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. The St. Mary's and St. Joseph Rivers join a few hundred yards east of this point and form the Maumee River . . . — Map (db m17064) HM|

It could also serve as a model for flood control in other sections of the country. The Headwaters Park Commission was formed to implement and fund the plan that is now Headwaters Park.

The Bog Trail leads to a depression in the moraine created when a large piece of ice broke off the melting glacier.
Bogs like Pinhook are relics of our glacial past. Trapped in the pulverized clay and rock left behind by a melting glacier, Pinhook Bog began as a kettle lake. Cut off from ground water, . . . — Map (db m75623)|
|Indiana (Owen County), Cloverdale — Cataract Falls|
Cataract Falls are the result of oceans and ice.
The limestone outcroppings that form Cataract Falls formed millions of years ago when this region was covered by a large shallow ocean.
Layers of calcium-rich materials fell to the ocean floor.
As layers accumulated, their weight pressed down, creating limestone.
More recently, glaciers extended south into the Cataract Falls area. Ice blocked the natural drainage of Mill Creek, creating a large lake. The limestone bedrock became . . . — Map (db m74183)|

|1. Dig a huge hole with a glacier. Use the ice to grind up millions of tons of rock and dirt and make ridges around the edge of the hole.
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|

|Indiana (Wabash County), Lagro — The Wabash River|
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)|
