| Dear Alan The
most recent edition of The Edinburgh Geologist arrived yesterday... I was particularly
interested in the piece about Agassiz as his name is perpetuated in Canada in
'Lake Agassiz'. Holmes refers to it in his textbook (1st edition, p. 242):
To the north-west [of the Great Lakes]
another series of lakes originated in much the same way, beginning their history
as marginal lakes which coalesced into a gigatic sheet of water referred to as
Lake Agassiz. The flat-lying sediments of the floor of this vanished lake form
the rich wheatlands of North Dakota and Manitoba. At first, Lake Agassiz drained
into the Mississippi, but lower outlets were uncovered to the north later on,
and the vast lake was reduced to remnants, including Lake Winnipeg, Lake Manitoba
and The Lake of the Woods.
This is
of partcular interest to me as our daughter and family live 200 miles north-west
of Winnipeg off the flat land which extends about 50 miles from Winnipeg in that
direction. Perhaps an article on Agassiz might be an idea. Yours,
Alyn Jones |
