    Whence comes this logic: no evidence = false?

    If it happens in the right place, such as in a deep valley or canyon, rainbows actually complete their arc shape and form a circle. So, I don't see why a rainbow couldn't simply stop at the ground, if it were in a flat place... But I've never heard an explaination on why you can't find the end of one, so maybe this isn't the greatest answer.

    The reason you can't find the end of a (normal) rainbow is that it is basically a mirage or an optical illusion. Light scatters through the water in the air and creates the rainbow effect, but the rainbow itself isn't an object. If you're moving around, it moves with you. As for why you might have a rainbow effect as described in the OP, I'm clueless. I'd believe it if someone explained how temperature/water vapor/etc. can create a prism in the air though.

    I'd suggest that it may have something to do with crepuscular rays. It is possible that atmospheric condition were such that the particular ray in question was refracted slightly, leading to a rainbow or spectrum effect. That's my best guess, anyway.

    And yes, like you, I am reasonably certain that there is no way for a normal rainbow to have an 'end' - not even in a canyon or ravine.
