Overview

Juneau County. T14N-R4E, Sections 16, 21. 212 acres.

Description

Description

Located in a deep, cliff-lined coulee, Bass Hollow contains an undisturbed forested gorge of mesic hardwoods with sugar maple, basswood, and red oak. Other trees include yellow birch and black ash found in springy areas. Hemlock occupies north-facing cliffs. This site features one of the largest blocks of undisturbed southern mesic forest in the state. The topography is very steep with sandstone cliffs rising over 100 feet high in some places. The upper slopes and ridge tops support a dry to dry-mesic forest of red and white oaks, big-tooth aspen, and black cherry. The ground layer is diverse and contains herbaceous plants such as doll's eyes, blue cohosh, wild geranium, hepaticas, early meadow rue, mayapple, sweet cicely, lady fern, fragile fern, and silvery spleenwort. Bass Hollow is owned by the DNR and was designated a State Natural Area in 1999.

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
