If you mean the fact that there's snow and peaks suggests that it couldn't possibly be California, you don't know much about California. An image more or less like this could absolutely be taken in the Sierras, especially if there was some color manipulation on that water. Of course, close inspection of that peak in the background will reveal it to be too tall for the Sierras, but that's not so obvious that it makes sense to ridicule someone for not seeing it immediately.
