creek gravel is different from road gravel - I don't think there's a tire that will stay up in what are basically bearings.
For gravel roads with irregular chert gravel, I like a fat tire, 35+. The fatter the better, for more float in the deep sections. If it's mostly dirt with gravel, or the gravel is very compacted, 30mm road tires will work okay. I used to ride inverted knobbies, but I don't anymore. I think they're just heavy. They're tough, though. The Ground Control is a great tire - I'd ride it. 25 psi seems low, but I'm heavy. Lowering the pressure in gravel helps me a lot.
