I have a great appreciation for railroad structures, especially bridges or trestles. So to me, a waterfall, bridge and railroad are a knockout combination. Sunset Falls on the BNSF Scenic sub is a great location and I've got a few shots there.

I'd be interested in opinions on the two different locations and if the format of the photo has a bearing on it's appeal.

Here's a recent shot from across the river, in portrait format:

or up close to the top of the falls:
