On Sunday,
June 7, I drove due north up ND 20, and crossed the border into Manitoba,
Canada. The officer there asked me if I
had any firearms (crazy Americans), and then why I was entering Canada in such
a remote location (“due north of Devil’s Lake”). He was away with my passport
for a while, but came back with it and sent me through with a smile.
I weaved
slightly west to MB 10, which took me through Riding Mountain National Park. This
area of higher elevation is striking because it is mountains and forest in the
midst of prairieland. It is also home to
a large number of elk, bears, and other animals, although I didn’t see any of
them. Still it was very pleasant to
drive through.
Riding
Mountain NP is interesting for another reason. It represents the edge the
gigantic ice-age Lake Agassiz, of which Lake Winnipeg and Lake Manitoba are the
largest remnants. Lake Dauphin, which I
went to, is another remnant, as is Lake of the Woods along the northern edge of
Minnesota. Lake Agassiz existed in part because
the weight of the glacier, some two miles thick, actually depressed the land
surface of the earth. As the glacier
melted, this area became a lake with about the same surface area as the Black
Sea today, and larger than all of the Great Lakes combined. Periodically it
would breach its banks and empty into some watershed or another, usually down
what is now the Minnesota River into the Mississippi, or east through what is
now the St. Lawrence River. As the ice
receded, however, the land surface rose again in a process called isostatic
rebound. As it did these drainage routes
were cut off. Finally, about 8200 years
before present (this is from Wikipedia), an ice dam constraining the water
collapsed and the entire lake, with the exception of the remnants referenced
above, emptied via the Mackenzie river into the Arctic Ocean. This caused sea levels to rise globally
somewhere between 3 and 9 feet, in a matter of weeks or at most months. Some have speculated that this event may be responsible
for some important flood myths, including the Bible’s.

Manitoba Now and Then: Riding Mountain NP, Lakes Winnipeg, Manitoba, et al; Glacial Lake Agassiz |
I spent the
night in the town of Dauphin (pronounced like “Dolphin” without the L), back in
the prairie. On Monday morning, I took a
short excursion east to see one of the Lake Agassiz remnants, Lake
Dauphin.

After that I
rode west for the rest of the day to Saskatoon, Saskatchewan. Much of my trip was over the Yellowhead
Highway, which has apparently been a well-established route for hundreds of years,
and perhaps long before that. Along the way
I chatted with people who commented that there had been a lot of rain in the
past few years, and as a result there are ponds in many places where there are
not usually ponds. All of this area is “basin,” apparently, like Devils Lake in
North Dakota. The amount of rain varies
significantly from year to year and decade to decade, and with no place to go,
the water levels rise and fall much more dramatically than in other areas.
