Trempealeau National Wildlife Refuge

Trempealeau National Wildlife Refuge is a National Wildlife Refuge located along the Upper Mississippi River in extreme southern Buffalo County and extreme southwestern Trempealeau County in Wisconsin, United States.
It is in part a wetland consisting of backwaters away from the Mississippi and Trempealeau River, and is a significant element of the Mississippi Flyway. It is part of the Driftless Area, a portion of North America which remained free of ice during the last ice age, creating in part the deep gorge of the Mississippi, quite visible from this refuge.
It is also a sand prairie, including grasses such as big bluestem, indiangrass, and switchgrass capable of growing to in height.
