This site is located on the Tongue River and consists of Icelandic State Park which has an impoundment (Lake Renwick), and the adjacent Gunlogson Nature Preserve.

With regard to the species listed by Stewart: a pair of Barred Owls was present in Gunlogson in the early 1980s. Alder Flycatcher is more likely than Willow Flycatcher. Sharp-shinned Hawk may not nest here. Otherwise the species listed by Stewart are thought to occur regularly within the Park or Gunlogson Nature preserve.
The conifer plantings have breeding Yellow-rumped Warbler and Purple Finch. Notable records for other species include those for Boreal Owl and Northern Saw-whet Owl. Northern Cardinal has been recorded in the campground. The park is one of the better places in eastern North Dakota to look for Bohemian Waxwing (winter), Golden-crowned Kinglet, and both species of crossbill.
Ruffed Grouse are regularly observed in Gunlogson Arboretum, and sometimes in Icelandic State Park.
As is usually the case, park management strives to balance human use against goals of preserving our natural heritage.
There needs to be a willingness of the state government to provide adequate funding devoted to preserving the natural heritage of the park. This includes combatting invasive species.
In 1963 G.B. Gunlogson donated 200 acres of property that had been in his family for 80 years. A large bog-like area that lies between the Gunlogson homestead and the community of Akra to the east is quite unique for North Dakota.
Icelandic State Park is a highly popular camping destination. The lake is used for fishing, boating, and swimming.Gunlogson Nature Preserve was set aside and is being managed to preserve the habitats that are found there in.The Pioneer Heritage Center and the Gunlogson Homestead and Nature Preserve serve to preserve Icelandic heritage and the early human history of the area. Several buildings are devoted to this purpose.
