I like the Pebble Beach Resorts logo for its simplicity and the fact that it represents a scene that you would see if you went there. We recently cleared some land at Thunderbird to open up an amazing view of the river, and I would like to make that our signature attraction, similar to the way the cliffs and ocean view are the signature of Pebble Beach.
Key themes for the logo would be: nature, curving river, elevated view, river grasses, beauty, trees - oak,willow, etc.
See ThunderbirdHills.com for more photos/information.
Great photo albums of the course and river here:

Simplicity is important, something that would be a recognizable image on the back window of a car - see the South Carolina Flag.
