Terrible Grand Canyon movie

I went to see an IMAX movie with people at work. I thought it was supposed to be on the Grand Canyon, instead it was about the Colorado River and why it was at risk. Oh, and the movie was crap.

One of the major points they made about the river was that it was terrible how low the water level is going because of drought. Of course the drought is being caused by global warming. Then 10 minutes later they talk about a Native American tribe that stored water from the river. The tribe was wiped out when they had a 50 year drought. So when the Native Americans ran into problems it was mother nature, when it happens to us, it's our fault.

If that were the only faux pas, I might have let it pass. But they went on to talk about the dams on the river. First they talked about the Glen Canyon dam (which they just called the grand canyon dam) and Lake Powell. Then they went on to talk about the Hoover dam, saying it was built in the 60s. Just a little bit of effort would have corrected this problem, putting the right dam in the right decade.

And apparently engineers are evil. So are dams, since they only provide abundant clean energy and prevent flooding. Oh, and they make the water nice and clear by letting the sediment settle out. BUt apparently clear water is a bad thing (although they never explained why that might be, except to say that it was how the river got its name, which also wasn't explained).

They also showed before and after pictures of what the river looked like when it was first explored, then finding the places and taking new pictures. So the result was a sandbar disappeared (which given the 80 years between pictures was likely inevitable because that the sort of things sandbars do), and the other picture showed a lot of plants. Apparently when the river still flooded it killed all the plants (although in fairness the type of plant that was shown was a non-native species, so maybe a bit of biblical cleansing would be a good thing).

Anyway, the three minutes of factual, and perhaps useful, information hidden in the movie were completely submerged in garbage. Oh, and the information/misinformation was further submerged against in the story of a writer writing about the Colorado river and taking a rafting trip with his daughter. Because apparently in 40 years there won't be a Colorado river anymore.
