NOTE: I now believe this animal to be Indricotherium, although with a shorter neck. We've had fun with it. Read on. . . .
A number of years ago, a tapir fan (I think it was hyrax; if it was someone else, please remind me!) told me about this phenomenon - a huge tapir sculpture along a highway in "nowhere" Oregon that didn't quite look like a tapir. After I moved to Oregon, I thought I'd be on the lookout for it, and guess what? We drove past it purely by accident on May 6, 2005, on the way to Crater Lake. I just re-found the photos. It has some tapir characteristics, and some clearly not. But I can't think what else it was intended to be. Certainly they'd know what a cow looked like, or a horse, and this is no rhino.
