Very nice video. That's a very formidable rig you have there. On a critique note, the text was a little annoying because it took too long for an effect to occur. Effects should be nice a punchy for the most part. Otherwise good job!
Steve to answer your question to Boss I pulled this off of google earth.
Manicouagan Reservoir (also Lake Manicouagan) is an annular lake in central Quebec, Canada. The lake covers an area of 1,942 km², and its eastern shore is accessible via Route 389. The island in the centre of the lake is known as René-Levasseur Island, and its highest point is Mount Babel. The lake and island are clearly seen from space and are sometimes called the "eye of Quebec." In 2007, the Manicouagan lake was astronaut Marc Garneau's nomination for the CBC's Seven Wonders of Canada competition.
If you read the wiki on this it says that this lake was created from a 3 mile diameter asteroid.
