Experienced photographers often choose a faster shutter speed to freeze the motion of a large waterfall, accentuating the shape and texture of the spray...a speed of at least 1/125 of a second or faster will freeze the water's motion.
Eric, the other pieces of the puzzle to zeroing the proper shutter speed are the lens choice and distance from the fall. In 35-speak, for freezing motion, "one over the focal length of the lens" is starting point, and you go from there.
But motion is relative and typically, the closer to the falls and the longer the lens, the faster the corresponding shutter speed.
Students this past May tested this and we concluded from across the valley with the falls at their peak, that between 1 and 2 stops below 1 over the focal length gave enough motion to convey the power of the fall without it looking like a white tornado.
When we opted to freeze the motion entirely, it looked like an icecycle, which is nothing like Ted's snap.
But up close, from the trail, is a completely different matter. There, the balance between implied motion and actual motion is trickier, and a faster shutter speed used at the precise moment to capture the curls at their apex seems to the key.
Pushing some PROVIA 100 a couple stops seemed to be the ticket. If my memory serves me, what is also amazing about Ted's photo is that the sun is included, and there is a spectacular starburst but no flare. Just slivers of water that resemble individual hairs peeling off a twisted column of water that looks like one of those carved candles.

I did not take enough food and water, so I guess I "bonked".
Join the club! I hiked down from Mt. Hoffman via that trail and when I got to Mirror Lake, I made a beeline (more of an awkward stumble) for the payphone. That trail takes every bit of energy you have in exchange for the awesome views.
And Vaughn, the more I hear of the antics of those boys, the more I get a vision of you as a sow with three cubs starring in a Disney feature.
