Lack of rain has left many rivers at low levels unseen for decades,
creating problems for river commerce and recreation and raising concerns
about water supplies and hydropower if the drought persists into next
year, as many fear.
But for the curious, the receding water is offering an occasional treasure trove of history.
An old steamboat is now visible on the Missouri River near St. Charles, Mo., and other old boats nestled on river bottoms are showing up elsewhere. A World War II minesweeper, once moored along the Mississippi River as a museum at St. Louis before it was torn away by floodwaters two decades ago, has become visible — rusted but intact.
Perhaps most interesting, a rock
containing what is believed to be an ancient map has emerged in the
Mississippi River in southeast Missouri.
The rock contains etchings
believed to be up to 1,200 years old. It was not in the river a
millennium ago, but the changing course of the waterway now normally
puts it under water — exposed only in periods of extreme drought.
Experts are wary of giving a specific location out of fear that looters
will take a chunk of the rock or scribble graffiti on it.
"It appears to be a map of prehistoric Indian villages," said Steve Dasovich,
an anthropology professor at Lindenwood University in St. Charles.
"What's really fascinating is that it shows village sites we don't yet
know about."
Old boats are turning up in several locations, including sunken steamboats dating to the 19th century.
That's not surprising considering the volume of steamboat traffic that once traversed the Missouri and Mississippi
rivers. Dasovich said it wasn't uncommon in the 1800s to have hundreds
of steamboats pass by St. Louis each day, given the fact that St. Louis
was once among the world's busiest inland ports. The boats, sometimes
lined up two miles deep and four boats wide in both directions, carried
not only people from town to town but goods and supplies up and down the
rivers.
Sinkings were common among the wooden vessels, which often were poorly constructed.
"The average lifespan of a
steamboat on the Missouri River was five years," Dasovich said. "They
were made quickly. If you could make one run from St. Louis to Fort
Benton, Mont., and back, you've paid for your boat and probably made a
profit. After that, it's almost like they didn't care what happened."
What often happened, at least on the Missouri River, was the boat
would strike an underwater tree that had been uprooted and become lodged
in the river bottom, tearing a hole that would sink the ship. Dasovich
estimated that the remains of 500 to 700 steamboats sit at the bottom of
the Missouri River, scattered from its mouth in Montana to its
convergence with the Mississippi near St. Louis.
The number of sunken steamboats on the Mississippi River is likely
about the same, Dasovich said. Steamboat traffic was far heavier on the
Mississippi, but traffic there was and is less susceptible to river
debris.
Boiler explosions, lightning strikes and accidents also sunk many a
steamboat. One of the grander ones, the Montana, turned up this fall on
the Missouri River near St. Charles. The elaborate steamer was as long
as a football field with lavish touches aimed at pleasing its mostly
wealthy clientele. It went to its watery grave after striking a tree
below the surface in 1884.
The U.S. Coast Guard and Army Corps of Engineers urge sightseers to
stay away from any shipwreck sites. Sandbars leading to them can be
unstable and dangerous, and the rusted hulks can pose dangers for those
sifting through them.
Plus, taking anything from them is illegal. By law, sunken ships and their goods belong to the state where they went down.
While unusual, it's not unprecedented for low water levels to reveal historic artifacts.
Last year, an officer who patrols
an East Texas lake discovered a piece of the space shuttle Columbia,
which broke apart and burned on re-entry in 2003, killing all seven
astronauts aboard. And the remains of a wooden steamer built 125 years
ago recently were uncovered in a Michigan waterway because of low levels
in the Great Lakes.
But treasure hunters expecting to
find Titanic-like souvenirs in rivers will likely be disappointed if
they risk exploring the lost boats.
"It's not like these wrecks are
full of bottles, dishes, things like that," said Mark Wagner, an
archaeologist at Southern Illinois University-Carbondale. "If there was
anything on there in the first place, the river current pretty much
stripped things out of these wrecks."
Such was the case with the USS
Inaugural, a World War II minesweeper that for years served as a docked
museum on the Mississippi River at St. Louis. The Great Flood of 1993
ripped the Inaugural from its mooring near the Gateway Arch. It crashed
into the Poplar Street bridge, and then sank.
In September, the rusted
Inaugural became visible again, though now nothing more than an empty,
orange-rusted hulk lying on its side not far from a south St. Louis
casino.
