INTERNATIONAL FALLS, MN (KDAL) - Voyageurs National Park has partnered with Polaris Industries for the funding of three new snowmobile shelters now available for use adjacent to trails at Black Bay Portage, Grassy Bay and Kettle Falls.  The shelters are designed to offer shelter from the wind and include benches and maps but do not offer fire rings.  Polaris also donated two wide track snowmobiles to assist park staff with winter safety and maintenance duties.
