HOLDERNESS — Squam Lakes Natural Science Center holds its annual Clean Up Day on Saturday, April 19 from 9:30 a.m. to 1:00 p.m.
Clean Up Day prepares the Science Center's trails and grounds, including Kirkwood Gardens, for opening day on May 1. Some projects are messy and most work is outdoors so volunteers are encouraged to dress appropriately. Groups are encouraged to help out at Clean Up Day or another day leading up to May 1. Special projects are available for organized groups.
