I think it might be the most important two feet of clay in the entire world, 14 inches of clinging, grasping wet sticky ooze that made Teddy Roosevelt a two term President, inspired the effort that created the American century, and offers a lesson in the history of the world we live in - that we all have feet of clay.
The two feet had to be clay because clay holds water, and this particular clay was created over thousands of years by limestone being eroded by the dark acidic waters of a lake surrounded by a dense forest, such as in today’s Wisconsin Dells (above). This particular ancient dell has been called "Lake Chicago", and if the clay it produced had been less than two feet high, then the clay would not have mattered.
If it had been much thicker than two feet then in 1674 Lois Jolliet (above) would have returned from his exploration of the Mississippi by a different route and the history of the United States of America would have been very, very different. Two feet was just thick enough to be difficult to overcome, but it could be over come. And although Monsier Jolliet was the first European to see the clay, he did not really see it.
Jolliet wrote his superiors back in France that there was a easy way to travel from the body of fresh water called by the native Americans as Michi gami to the Mississippi River "We could go with facility to Florida in a bark (canoe), and by very easy navigation, " wrote Jolliet.. "It would only be necessary to make a canal by cutting through but half a league (about a mile) of prairie."
But Jolliet had arrived at the edge of Lake Michigan (the ancient "Lake Chicago") when most of the clay was hidden from view by the spring runoff. So the obstacle and the advantage of the clay would have to wait over a century to be revealed.
In the summer of 1818 fur trader Gurdon Hubbard, retracing Jolliet's route for the American Fur Company, made his first trip up the south fork of the ‘Shikaakwa’ (or skunk weed) River from the village of “Chicago” on the western shore of Lake Michigan (above) .
Hubbard followed the river upstream until the open water gave out. From there, unlike Jolliet, Hubbard was forced to portaged for seven miles. This was because Hubbard was traveling in the summer, when the water was low.
“Our empty boats were pulled up the channel," wrote Hubbard, "...until the Mud Lake (above) was reached, where we found mud thick and deep, but only at rare intervals was there water….”
Fighting off schools of leeches and clouds of mosquitoes, it took Hubbard three days to cross the 7 miles of clay and mud before reaching the clear flowing water of the Des Plaines River on the other side of the Valporaso morraine. But as Jolliet had said, the Des Plaines River ran into the Illinois River, which joined the Mississippi River, which carried Hubbard and his bateau’s 12 tons of trade goods into the very hinterland of the continent. And perhaps this might be a good point to pause and explain why this was where the clay gathered.
Three times over the last 300,000 years glaciers have ground southward across North America, successively plowing the landscape bare and then recreating it on their retreat. When the penultimate of the glaciers paused here 25,000 years ago, they bulldozed a 10 foot high north-south ridge of clay (above, foreground) from the bed of the ancient Lake Chicago. This ridge is called the “Valparaiso Terminal Moraine”.
Chicago writer Libby Hill has noted this moraine is not a mountain range, but "a very slight rise of maybe about 10 feet that...in times of low water... a subcontinental divide"(above), between the drainage to the Atlantic and drainage to the Mississippi river. The 24 inch high ridge of clay was the cap on the moraine which kept the present Lake Michigan from draining to the west and south down the Des Paines River into the center of the continent. Instead the waters of Lake Michigan were forced to find a another path to the ocean , eastward, toward the Saint Laurence River, and giving birth 12,000 years ago, to Niagara Falls. But from the moment Hubbard clawed his way through the sucking, engulfing clay, Americans were anxious to dig through it.
The dream of breaching that moraine was first achieved by the 96 mile long "Illinois and Michigan Canal", begun 1836, discontinued in the panic of 1837, and not completed until 1848. It drained the Mud Lake and provided locks (above) to lift the narrow canal boats and their 100 ton loads 35 feet up to the level of the Des Plaines River at Jolliet.
From there another series of locks provided an easy journey so Michigan apples could be sold in St. Louis and New Orleans. That first canal established Chicago as a transportation hub.
But the growth of Chicago presented its own challenges. By 1867, the 300,000 citizens of Chicago had so fouled their Lake Michigan shoreline that to reach clean drinking water they were required to tunnel two miles out under the lake.
The success of such a "big government project", like the water tunnels and the "Illinois and Michigan" canal encouraged the locals to dream of breaching the moraine in a more grand fashion, and of converting Chicago from a mere lake port into a seaport.
To sell the plan to conservative voters, politicians also pitched the idea of reversing the flow of the Chicago River, to carry Chicago’s waste away from the lake, which was the source of the cities’ drinking water. Pumps would draw lake water into the Chicago River, and then send it up and over the "Valparaiso Moraine" before sending it down the new "Sanitary and Ship Canal".
So on Saturday, 3 September, 1892, Frank Wenter, President of the new Metropolitan Sanitary District of Greater Chicago, turned the first ceremonial shovel of earth in the village of Lemont, Illinois (above), which was to be the central point of the Sanitary and Ship Canal, because it was one of the highest elevations between the rivers and a good source of stone, for lining the canal.
The new canal, built in the name of progress and “clean water”, would excavate 44 million cubic yards of clay and stone...
...to create a passage 28 miles long, 202 feet wide and 24 feet deep, which would terminate, for the time being, in a dam and the first in a series of locks at a new town named Lockport, Illinois. These locks could take ships and barges up to 600 feet long and 110 feet wide. Using steam power it would take eight years to finish the initial work and the final cost of this version of the canal would prove to be $45 million.
The New York World newspaper examined the social changes this ‘progress’ brought to the sleepy village of Lemont (below). Out of the town's 9,000 residents, wrote the paper, “…4,000 are gamblers, thieves, murderers or disorderly women. There are 100 saloons, 40 gambling houses, 20 dance houses and three theaters…Everything is running wide open and licensed...Within three months 30 dead bodies have been found…and no one has been punished…"
The paper then added, "Every Sunday excursions of the worst classes go to Lemont from Chicago.”
When this canal opened the Mississippi River town of St. Louis would lose the race to become the railroad center of the nation, The new canal would allow Chicago grain and livestock markets to set prices for Missouri farmers. When the Missouri business interests finally awoke to the threat, they realized a purely monetary argument against the canal lacked a sense of urgency. So, as the Sanitary and Ship Canal got ready for an official opening set for the spring of 1900, Missouri sued in federal court. The Missouri Attorney General claimed, “The action of the Chicago authorities in turning their sewage into the Mississippi River for the people of St. Louis to drink ,is criminal, and Chicago knows it.”
Yea, maybe. But in response, in December of 1899, the Metropolitan Sanitary District of Greater Chicago released their own "scientific study" which "proved" all sewage had been cleansed by biological action by the time it reached Peoria, barely half way to St. Louis. And besides, the Chicago lawyers argued, St. Louis drew most of its drinking water from the Missouri River, not the Mississippi.
And besides that, the city of St Louis drained their own a sewage into the Mississippi River, above their own secondary intake (above) on the Mississippi. If anybody was forcing the citizens of St. Louis to drink sewage, it was St. Louis, not Chicago!
And to go further. in an attempt to present the United States Supreme Court with a faite accomplie on this issue, on 2 January 1900, Chicago opened the new southern locks connecting the Des Plaines River with the Mississippi River, at Alton, Illinois. Not to be deterred, on Wednesday, 17 January, 1900, Missouri filed a request for an injunction from the Supreme Court to stop new canal from being opened at the northern end. And suddenly the Chicago lawyers and politicians did not feel so certain about their case.
To forestall the Supreme Court, on Sunday, 21 January, 1900, the directors of the Chicago Sanitary District tried to quietly produce another fait accompli (above). The Chicago Tribune explained why that did not prove a simple thing to achieve.
“…B.A. Eckhart was the first to reach the narrow watershed at Kedzie Avenue and Thirty-filth Street...Less than eight feet (of ice and frozen clay) separated the waters of the lakes from the waters of the Mississippi…It was exceedingly slow work, for the clay was (frozen) like a rock…Four large charges of dynamite were placed in the ridge…A few fugitive pieces of clay did fly into the air. But as a grand opening it was a failure…."
"Then the ambitious trustees, armed with their shovels, descended into the cut and began to push away the pieces of clay and ice which held back the lakes…With the regularity of a pendulum the arm of the dredge (above, top center) swung back and forth….The ice from the river rolled in and blocked the channel…"Push the ice...away with the arm." shouted the foreman…The (dredge) arm dropped behind the ice gorge and then with resistless motion swept the whole of it into the Mississippi Valley. .... "It is open! It is open!" went up from scores of throats as the water at last (flowed)…Like school boys on a vacation, the drainage officials waved their arms and shouted.”
Indeed, it was done. On 2 May, 1900 Admiral George Dewey, hero of the battle of Manila Bay, dedicated the official opening. But it would not be until 1907 that a lock and power plant would be built (above) to power and control the 36 foot climb from the canal level at Lemont to the level of the Des Plaines River, to complete the dream of ocean going ships reaching the Mississippi via Chicago.
Within a decade after the canal opened the construction techniques for the locks used to raise and lower ships over the Valparaiso Moraine (above)....
...would be used by many of the same engineers in the construction of the Panama Canal (above). It was that endeavor, championed by President Theodore Roosevelt, which ushered in the American Century. The lesson here is that no infrastructure, be it the creation of the Sanitary and Ship Canal, or manned space flight, or the creation of the interstate highway system, or a national Internet access system, is ever a wasted effort. It is the lessons learned from the endeavor that make the future possible.
And the Chicago canal proved something else as well. As recorded by William C. Alden in the 1902 “Chicago Folio” for the U.S. Geological Survey Atlas of the United States (volume #81), excavations for the canal and its locks unearthed the history of the entire continent.
Beneath the clay and beneath the limestone, the canal unearthed the bedrock of Chicago; “Potsdam Sand Stones”. So the bedrock of Chicago is petrified beach sand, the bottom of an ancient shallow sea. We know it was shallow because coals left their fossils in the sand and their lime rich skeletons (above) hundreds of feet thick embedded in the sand stones. Over millions of years that sea had been replaced with a freshwater lake, surrounded by trees, whose leaves fell into the waters, turning the waters acidic, and converting the top layer of the limestone into clay.
And then the glaciers had come, and scrapped across the clay, piling it up in a terminal moraine, which prevented the glacial melt waters from finding their way to the Mississippi river, until humans arrived and stood upon their own two feet of clay and thought, "I shall do this". And it was done. It was not done without a paying a price, but life requires a price be paid even if you decide to do nothing.
