Overview

Location

Within the Northern Highland-American Legion State Forest, Iron County. T42N-R4E, Sections 8, 9, 16, 17. 1,290 acres.

Description

Description

Frog Lake and Pines features an undisturbed wilderness lake surrounded by old-growth northern dry-mesic forest in a large lowland bordering the Manitowish River. The 42-acre lake is a deep, soft seepage lake with a dense community of submergent aquatic vegetation including white and yellow pond-lilies, bladworts and spike rushes. Wetlands predominate along the shoreline with bog, sedge meadow, and lowland conifer-hardwood swamp. The bog has an abundance of leather-leaf and Laborador-tea with numerous scattered small trees, sedges, and other ericaceous species. The low conifer-hardwood swamp contains species such as white and black spruce, tamarack, thimbleberry, and three-leaved gold-thread. The remaining shoreline is upland forest consisting primarily of red and white pines some that are more than 2 feet in diameter with other trees including white birch, aspen, red maple, and balsam fir. The understory varies in shrub density from a thicket of hazelnut to a fairly open understory with bracken fern, bunchberry, wild sarsaparilla, American starflower, rough-leaved rice grass, and Canada mayflower. Migrating waterfowl make extensive use of the lake. Frog Lake and Pines is owned by the DNR and was designated a State Natural Area in 1983.

Maps

The DNR's state natural areas program is comprised of lands owned by the state, private conservation organizations, municipalities, other governmental agencies, educational institutions and private individuals. While the majority of SNAs are open to the public, access may vary according to individual ownership policies. Public use restrictions may apply due to public safety, or to protect endangered or threatened species or unique natural features. Lands may be temporarily closed due to specific management activities. Users are encouraged to contact the landowner for more specific details.

The data shown on these maps have been obtained from various sources, and are of varying age, reliability, and resolution. The data may contain errors or omissions and should not be interpreted as a legal representation of legal ownership boundaries.

Recreation

Very few State Natural Areas have public facilities, but nearly all are open for a variety of recreational activities as indicated below. Generally, there are no picnic areas, restrooms, or other developments. Parking lots or designated parking areas are noted on individual SNA pages and maps. Trails, if present, are typically undesignated footpaths. If a developed trail is present, it will normally be noted on the SNA map and/or under the "Access" tab. A compass and topographic map or a GPS unit are useful tools for exploring larger, isolated SNAs.

Allowable activities

In general, the activities listed below are allowed on all DNR-owned SNA lands. Exceptions to this list of public uses, such as SNAs closed to hunting, are noted under the "Access" tab above and posted with signs on site.

  • Hiking
  • Fishing
  • Cross country skiing
  • Hunting
  • Trapping

Prohibited activities

  • Camping and campfires
  • Collecting of animals (other than legally harvested species), non-edible fungi, rocks, minerals, fossils, archaeological artifacts, soil, downed wood, or any other natural material, alive or dead. Collecting for scientific research requires a permit issued by the DNR
  • Collecting of plants including seeds, roots or other non-edible parts of herbaceous plants such as wildflowers or grasses
  • Geocaching
  • Horseback riding
  • Rock climbing
  • Vehicles, including bicycles, ATVs, aircraft, and snowmobiles except on trails and roadways designated for their use
