June 7 – Anniversary of the End of a Manitoba Voyage

Posted on June 7, 2015

Do you know what the “mouth” of a river is?

It's one end of the river – the end that is “downstream” – the part where the river flows into a lake, reservoir, ocean, or maybe just another river.

That is the opposite end from the “headwaters,” the source of the river, which is often an underground stream or a melting glacier but is sometimes a lake or a marsh.

On this date in 1800, famed explorer David Thompson reached the mouth of the Saskatchewan River, in what is now Manitoba, Canada. The river empties into Lake Winnipeg.

Many Americans don't know much about Canada, especially the central provinces of Saskatchewan and Manitoba. These two provinces are largely prairie, and of course a few lakes.


And when I say “a few lakes,” I mean over 110,000 lakes in Manitoba alone, including the tenth-largest freshwater lake in the entire world, Lake Winnipeg.



I don't know if you noticed that I referred to David Thompson as a “famed” explorer. He is widely known by Canadians, but not so much by citizens of the U.S. Thompson surveyed huge swaths of land and traveled miles of rivers; he filled in gaps of knowledge about almost two million square miles of Canada!
This map shows Thompson's exploratory routes.






















Here are some cool things to see in Manitoba:

The Canadian Museum for Human Rights has interactive exhibits and a Tower of Hope.
The interior of the Manitoba legislative building features hieroglyphics, free-masonic symbols, and numeric codes – but in a pretty subtle way. A tour guide is helpful to point out such things as a bust of Medusa, the repeated use of the numbers “666” and “13,” and Egyptian sphinxes!

Check out the beautiful Manitoba lake below. There seems to be a mysterious "hole" in the lake.

U.S. Patent for First Successful Roller Coater – 1885

LaMarcus A. Thompson built the first successful roller coaster in Coney Island, New York.

He called it the “Gravity Pleasure Switchback Railway”—a name entirely unlike roller coaster names these days (the Cyclone, Viper, Intimidator are three examples). The ride only cost five cents (again, how different from today!—a coaster in Las Vegas costs $14 for just one ride!), and passengers sat sideways in cars pulled by gravity down low, gentle waves of a 600-foot rail line (in contrast to the steep hills, vertical loops and corkscrews of today). Thompson's coaster only reached speeds of 6 miles per hour (nowadays some coasters reach 100 miles per hour!), but people loved it and lined up to ride. Apparently the daily earnings of $600 per day were astounding. (I guess, when it's a nickel at a time!)
The roller coaster's beginnings are in Russia, where people would ride blocks of ice (with straw or fur seats) down wood-framed slides on specially constructed hills. In the summer wheeled carts rolled riders down large, undulating wooden ramps not unlike Thompson's railway.

Apparently in many languages roller coasters are called what could be translated as “Russian Mountains.” But in Russia the name for this sort of ride is “American Mountains”!

Celebrate roller coasters!
  • Design a fantastic ride just how you like it. Consider, not just the hills and turns and loops, but also the car design, the name, and the decorations.
  • Take a ride? If you are lucky enough to live near an affordable coaster, you could give in an honorary spin today.
  • Take a virtual ride. There are two links at the bottom of this earlier post. 
  • Virtually build a coaster or two. Roller coaster simulator gamesare lots of fun and can teach you a thing or two about physics, too. Try the free demo of No Limits Roller Coaster Simulator. 
  • Learn the physics of roller coasters from this primer.
