White Pine Hollow State Forest

White Pine Hollow State Forest is a 944-acre wooded area near Luxemburg in northeastern Iowa, including a 712-acre tract protected as both an Iowa State Preserve and a National Natural Landmark. Named for its old-growth white pines, it contains what is regarded as Iowa’s only remaining old-growth white pine stand. In the Driftless Area, its north-facing algific talus slopes and dolomite karst terrain of sinkholes, caverns, and sharp elevation changes created conditions that helped this relict grove survive from a colder past climate. More than 625 plant species have been recorded there, along with rare species such as the Indiana bat, Iowa Pleistocene snail, and northern wild monkshood.
