I would say it's a wetland that formed over centuries and centuries. It was wet ground, hydric soils, very damp, undrained. It was one type of wetland. When you put water on top of soils like that it turns it into a standing marsh. It's called Luther Marsh wildlife area. It's still a wetland. It's just a different class of wetland than it would have been. Wetlands form over hundreds of years. You can take hydric soils, flood them, and turn them into a marsh relatively quickly. That's the kind of timeframe we're dealing with for Luther Marsh.
