Mysteries of the Great Lakes - IMAX movie at American Museum of Natural History

Yesterday I went to the American Museum of Natural History in NYC and saw the IMAX movie "Mysteries of the Great Lakes".   Honestly, I had not spent a lot of time thinking about the Great Lakes but because of my interest in water, it was eye opening in many ways - not only seeing how big the Great Lakes are , but to be made aware of their natural beauty.  In focusing on water, it was most interesting to me to learn that The Great Lakes contain 20% of the world's fresh water supply and that it takes a drop of water 400 years to travel from the headwaters of Lake Superior to the edge of Lake Ontario.  Looking at the map was helpful.  

I was also most interested in the focus on wildlife that survives on life in the Great Lakes - including Eagles, Caribou and Sturgeon.  The segments on Sturgeon were amazing as they had been tracking this species' population for the past 20 years and had been tracking/studying a specific female sturgeon for the past 20 years.  Amazingly, the one scientist could identify her simply from the markings on her head.  At her most recent capture/release event her age was 120 years old!  Through their research they learned how to look at the scales or fins (can't remember which one) and, like reading rings in a tree trunk, scientists learned how to read the environmental conditions of the Great Lakes.  

Sturgeon of the Great Lakes had thrived by the millions for millions of years but had significantly declined in numbers due to over-fishing and pollution.   During the film, several pictures were shown from long ago ( maybe 100 years ago?) where the subjects of the pictures were proud of their businesses and lives and could display their most recent abundant catch of sturgeon.  From a 2010 perspective, it was hard to get beyond the waste and destruction, the man-hours and work dedicated to improving the environmental conditions of the Great Lakes and  reviving the sturgeon population.   It seems there are still 42 "hot spots" - where lake quality is highly degraded due to pollution coming from industrial waste and waste water treatment plants.  Hopefully clean-up in the lake can continue and we can learn to make better environmental choices.

This was a great movie and I encourage you all to see it.  Here are the showtimes for the IMAX showings at the New York Museum of Natural History.  You might want to check out some of the exhibits including the  Silk Road Exhibit.  One word of advice for the Silk Road, enjoy the journey, but don't get caught up in stamping your "passport".
