Located in Cottage Grove, this highly protected Scientific and Natural Area (SNA) features two sandy terraces along the river. Grey Cloud Dunes SNA is a sight to see. Help us further our restoration efforts at this special site!

After a brief orientation, volunteers will work with Friends of the Mississippi River ecologists to help remove sumac, a shrubby tree that would otherwise overtake this vital habitat. Other tending or restoration tasks may also be needed at this very important site.

Due to tool usage, including loppers and saws, this event is not suitable for youth. Please also note Grey Cloud SNA does not feature amenities – trails or restrooms.

Capacity is limited, in part to tread lightly on this special place but also to make sure everyone has a chance to ask questions about the site’s ecology. To learn more and register, visit https://fmr.org/events/2018/08/29/lop-sumac-grey-cloud-dunes-sna
