Ever wonder where road departments get the mountains of salt
they use each winter? Here in the Midwest, the
answer can be found deep under Lake Erie. The Great Lakes Radio
Consortium’s Ann Murray has the story:


Orvosh: “Step right in there.”


Murray: “Ok, thanks.”


For Don Orvosh, an elevator ride nearly 2000 feet underground is just part of the daily grind.


(sound of clanking)


“It’s about a four and a half minute ride to the bottom. 1800… about 1800 feet.”


Orvosh supervises the Cleveland salt mine owned by Cargill Corporation. It’s one of only eleven active salt mines in the country. The mine lies beneath the northern edge of Cleveland and extends about four miles under Lake Erie.


Orvosh: “Most people in the city don’t even realize there’s a mine right here.”


Murray: “Are you all the way down?”


Orvosh: “We’re at the bottom right now. This is it.”


(sound of opening air-lock door)


A few feet from the elevator, Orvosh walks through a series of air-locked metal doors. They rotate to reveal a subterranean repair shop. Massive dump trucks and cranes are fixed here. The cavernous room is also the starting point for hundreds of miles of tunnels. These tunnels connect a honeycomb of old and active areas in the mine. Everyday, 150 workers travel this salt encrusted labyrinth by truck or tram.


“We’re going to get in this little buggy here now and in a couple minutes we’ll be under the lake.”


Lake Erie is a geological newcomer compared to the salt buried below it. This bed – extending from upper New York to Michigan – was formed 410 million years ago. That’s when an ancient sea retreated and left behind its brine. Oil drillers accidentally discovered the deposit in the 1860’s. As Orvosh drives north through the dark passageways, he says salt wasn’t extracted here until many years later.


“This shaft was sunk in the late fifties and the actual mining of salt occurred, started in the early sixties so it’s been here 40 plus years.”


In the last four decades, the mining process has stayed pretty much the same. Orvosh compares it to the room and pillar method used in underground coal extraction. He points up ahead to a brightly lit chamber. Machine generated light bounces off the room’s briny, white walls. Its 20 foot high ceiling is bolstered by pillars of salt the size of double-wide trailers.


Orvosh: “This is an active production section. This is where we are mining salt.”


Murray: “What’s happening here?”


Orvosh: “He’s drilling the face here.”


A miner sits atop a machine with a large needle nosed drill. It bores six holes into the seam. Later in the day, workers will load explosives in the holes and blow out big chunks of salt. Farther into the mine, the loose salt from last night’s blasting is being scooped up by front-end loaders and dumped into a crusher. All of the big chunks are broken into small pieces. Then the salt is loaded on conveyor belts and sent to the mine’s three-story-high underground mill. Salt is crushed, sized, screened and sent to the surface by elevator.


All told, the crews at the Cleveland mine produce two million tons of salt a year. A sizable chunk of the 15 million tons of salt used on icy US roads each winter. Demand for road salt has skyrocketed since it was introduced as a de-icer in the early 1950s. But Robert Springer, a 27- year veteran at this operation, says each mine fights for a market share.


Springer: “It is a competitive market. There’s another salt mine just in the Cleveland area, out there in Morton, Morton Salt.”


Murray: “We needed you today. The roads were really icy. Do you look forward to icy days to keep production up?”


Springer: “I guess you could say we look forward to bad weather. We enjoy the bad weather because we know there’s going to be salt used.”


(sound of radio and weather report)


Back on the surface, Bob Springer has gotten his wish… Cleveland has just been hit with a winter storm. At least a dozen trucks swing through the mine’s loading dock to pick up tons of salt. Later in the day, salt will be dumped onto barges and transported across the Great Lakes to places like Chicago and Toronto. This is high season for road salt. The crews here know that come March, they’ll start rousing salt from its ancient bed for the winter of 2006.

Preserving Downtown Buildings Helps Stop Sprawl

As people move to homes and businesses in the suburbs they often abandon beautiful buildings. Some inner cities are now filled with boarded up store fronts and dilapidated high-rises. A group of architects hopes that people will be less likely to do this if they value good architecture and design. The Great Lakes Radio Consortium’s Tamar Charney has this story:

As people move to homes and businesses in the suburbs they often abandon beautiful buildings. Some inner cities are now filled with boarded up store fronts and dilapidated high-rises. A group of architects hopes that people will be less likely to do this if they value good architecture and design. The Great Lakes Radio Consortium’s Tamar Charney reports:


Flint, Michigan could be the poster child for a city left behind. Parts of the city have crumbled since Flint’s
auto industry moved away. But like
many older cities, there are dozens
of architectural gems here… (sound up)
like the Mott Building. It’s the city’s
tallest building and the exterior, the
interior, and every detail right down
to the doors on the elevators (sound
of elevator) are designed and
decorated in the Art Deco style.
Albert Ashley is a security contractor
at the Mott Building. He says a week
doesn’t go by without someone
asking about it.


(elevator bings and boings)


“It’s quite regular, quite regular we
get comments about it and the
architectural design and so forth…
well they can tell that it was pretty
old building and well kept, you know,
and the design is pretty much the
same throughout the building, so they
notice that and they like it.”


(Sounds of traffic)


One person who has always liked this
building is Ron Campbell. As a child,
he’d stand here on the corner of
Saginaw Street waiting for the bus.


“I can remember asking my mother,
‘how many stories is that?’ And I
probably pestered her with questions
to the point where she was ‘just be
quiet and wait for the bus.’ But…
‘How high is that compared with the
Empire State Building? How many
buildings do we have like that?'”


With that kind of early interest in
buildings, it’s no surprise Ron
Campbell grew up to become an
architect. And he’s now written a
guide to the architecture in Flint.
It’s a pamphlet with pictures and
blurbs about 34 places in the city.
It’s available at highway rest stops
and at businesses and museums.
Campbell says he’s trying to
teach people about the various styles
of architecture found in the city, but
he’s also hoping the guide can in
some small way combat urban sprawl
by celebrating places that are
beautiful, well thought out, and
designed to last. He thinks that if
more people paid attention to good
architecture in many older cities
they’d be less likely to abandoned
them in favor of new buildings and
developments.


“The Guide is to show, you know,
‘here’s what
can come from good design. It
doesn’t matter if it was built in
1800’s or today. If it’s good design
and it interfaces well, it functions well,
it’s going to be with us, and therefore
we should use it and not think of it
as disposable.”


The Guide to Flint Architecture is one
of many projects local chapters of the
American Institute of Architects are
doing to raise awareness about
architecture and the environments
that we build. Similar guides have
been created for cities ranging from
Duluth, Minnesota to Manhattan.


Celeste Novak is the president of
AIA Michigan. She says the buildings
in a city can tell stories about the
community’s past.


“They are a museum that we are all
participants in, and so it’s important
that people understand that
about the buildings and the communities,
and so that they begin to treasure their
communities and that’s one way we
can all have more livable
communities and really prevent things
like sprawl and the unpleasant places
we all find ourselves at when we’re grocery shopping.”


Those strip malls and big box stores
near the highway look very different
from the places shown in Ron
Campbell’s guide.


(sound of footsteps on bridge)


Campbell and I walk across a small
wooden footbridge in the heart of
downtown Flint. We’ve just left a
peaceful riverfront park designed by
a well known architect. On the other
side of the river where we’re going
sits Carriagetown. It’s where the
vehicle industry began in Flint.


“Oh, Carriage Town is rich in history –
this is the birthplace of General Motors
Company with the Durant Dort
Carriage factory.”


After years of neglect, this factory
from the late 1800’s has been
restored as have many homes in this
historic district. Ron Campbell says
he’s glad Carriage Town was never
torn down. It’s part of the city’s
industrial history. And Carriage Town,
like the Art Deco Mott Building and
many other places in the Guide to
Flint Architecture are nostalgic places
for Ron Campbell. They’re reminders
of his past and things he’s done over
the years.


“Those buildings, it re-kindles
childhood memories for me, but then
I look at the future, and what are we
leaving for our children and our
children’s children and hopefully it’s
something just as memorable.”


He says design decisions can
change a community for better or for
worse. He and other architects like
him want to encourage people to
think about the buildings they have
and to pay more attention to
aesthetics. The hope is society can
do a better job protecting historical
structures, preserving natural
resources, and by doing so
controlling sprawl.
