Update: It seems that this is an artificial kelp reef. However, we’re much more interested in the underwater ketchup farming! (Thanks guys )

Does anyone know what on earth this weird red stuff is off the coast of Anaheim, California?

Thanks to a few people, but Steven Lagavulin was first there

SeaWorld is a chain of theme parks featuring killer whale, sea lion and dolphin shows. When I first read about SeaWorld I was very confused by the fact that “Shamu”, the chain’s mascot killer whale, manages to appear twice a day at all three parks across the states. As it turns out the name Shamu is a registered trademark of SeaWorld and the 3 whales currently going by that title follow in the footsteps of a long line of “Shamu” performing whales.

The first SeaWorld we’re visiting on our tour today is SeaWorld San Antonio in Texas. You can use the officical park map to identify the various areas and rides.

Next stop is SeaWorld San Diego in California. In the thumbnail shot you can see a crowd has gathered for the dolphin show (official park map).

Our last stop is SeaWorld Orlando, Florida. Some of those who submitted this site were sure that the black splodge you can see in the pool is Florida’s version of Shamu the whale, but I’m not convinced.

Next up is the Amboy Crater, an extinct cinder cone in California’s Mojave Desert. It lies within a 70 square kilometre lava field, and it looks pretty impressive from up here!

Thanks to Art Jones.

The largest wine producer in the world, E&J Gallo Winery in Modesto, CA. The building is huge but it’s the tanks that are worth looking at -there must be a lot of wine in there!

The Los Angeles Memorial Coliseum hosted both the 1932 and 1984 Olympic Games and the Olympic torch, which resides at the east end, is still lit during football games. The Coliseum was also the site of the very first Super Bowl in January 1967.

Update: Thanks to Kate for the following info…

The swimming pool just to the south is, officially, the Los Angeles Swimming Stadium. Slightly north of the Coliseum is the Natural History Museum of Los Angeles, and to the east of that is the Rose Garden (the carefully patterned garden area) and the California Science Center.

The airplane visible above the dirt area to the east (which is construction work) is part of the Los Angeles Aerospace Museum, and the big white dome-shaped thing to the south-east of the Coliseum is the Los Angeles Memorial Sports Arena.
