If you have snapping turtles around they are. Water or swamp often in sight of a nest. (Being within scent distance would be next. )
They will hike a ways to lay.
I've never seen one dig to lay eggs where it wasn't dry.
They probably still want some humidity/moisture in the soil still. Breathable though ; and not subject to being flooded.
Here in the North racoons and other critters dig them up.
Watched a fox trying to locate a nest before in daylight too. That nest got a wire milk crate set atop it.
Steep bank to river was around eighty yards away. Then a good forty or more yards down the steep slope to wet ground.
