Parking
There is no designated parking spot. Park along the shoulder of the road on 290th Ave. Do not block the nearby field access. It is not part of the preserve.

History
The Nature Conservancy (TNC) purchased 160 acres from Anna Gronseth in November, 1973, and named it Anna Gronseth Prairie. Between December, 1973 and March, 1999, THC made at least seven more acquisitions, each time enlarging this preserve. In 1993 TNC transferred a 648 acre parcel to the Minnesota DNR which became the Akron 4 Unit of the Rothsay Wildlife Management Area.

Wet Prairie
To get from the parking spot to the main portion of the preserve visitors will need to cross an intermittent stream and a drainage ditch. Many areas of the saline wet prairie complex will have some standing water in wet years, as in 2015. Waterproof footwear is recommended.

Rotten Egg Smell
In oxygen-poor environments, like wetlands, anaerobic bacteria reduce organic matter releasing as byproducts methane, which is odorless, and hydrogen sulfide, which smells like rotten eggs. A rotten egg smell was conspicuous on a part of the saline wet prairie complex when I visited there in June, 2015.

Parking

  Anna Gronseth Prairie   Anna Gronseth Prairie
  Park on the shoulder of the road. Do not park on the ditch crossing, as I did here. Though the landowner was kind enough to allow me to park here on this day, he needs this ditch crossing unblocked to access his field.
