Ice Caves No Longer Safe
The ice formations in Leelanau Township, north of the park, are no longer safe to visit. High winds have fractured the ice, moving it to the west. Huge cracks have formed in the cave arches, making them very unsafe and open water is now visible.
Sleeping Bear Dunes National Lakeshore Begins Plan to Restore Disturbed Lands

The National Park Service (NPS) is preparing detailed action plans for restoring non-historic lands throughout Sleeping Bear Dunes National Lakeshore (Lakeshore) to their natural state. To make certain that the impacts of restoring these lands are thoroughly evaluated, a Disturbed Lands Restoration Environmental Assessment (EA) will be prepared. The purpose of the EA is to ensure:
The disturbed lands will be separated into three principal management areas including:
1) Non-native weed infestations and threats. There is a need to aggressively manage specific invasive weed species that pose critical, expanding threats to the natural environs of the Lakeshore. These include plants such as garlic mustard, baby’s breath, purple loosestrife, Phragmites, and black locust. Possible manual, cultural, mechanical, chemical, prescribed fire, and biological control options have been researched for each invasive plant.
2) Formerly developed sites and sites disturbed by heavy public use. The developed/disturbed sites include former residences, former business sites, abandoned power lines, former driveways, gravel pits, refuse dumps, non-historic former agricultural fields, and impacted areas adjacent to popular attractions such as beaches and campsites.
3) Conifer plantations and windbreaks. Over 750 acres of conifers within the Lakeshore were planted 30 to 45 years ago. Many are tree species that are not native to North America and are now spreading into the surrounding native habitats. All are densely planted trees that may serve as prime sites for conifer insect and disease infestations leading to future native conifer die-offs. The lack of biological diversity at these sites is striking, and the plantations prevent natural succession into native mixed hardwood forest. The heavy fuel loads may serve as volatile ignition points for wildfires during drier periods. This threat to surrounding communities, private homes, and natural habitats is of major concern.
The Disturbed Lands Restoration EA process is just beginning. We welcome your ideas and insight to help identify what impacts and issues to consider as we continue this comprehensive restoration effort. Please provide your comments to us by December 31, 2007. The comments you submit during this “scoping” phase of planning will be incorporated into a range of alternatives and impact analyses in the EA. The EA will then be made available for further public review and comment in 2008 as we again solicit your input. Comments may be submitted by clicking here or mailed to the National Lakeshore at: Superintendent, Sleeping Bear Dunes National Lakeshore, 9922 Front Street, Empire, Michigan 49630.

The night sky is vital to many plants and animals that call Sleeping Bear Dunes National Lakeshore home and it holds a variety of meanings for many cultures. An unpolluted night sky is especially valuable to humans wishing to experience natural darkness, shooting stars, or the Milky Way.
