Lob Trees in the Wilderness
by Clifford Ahlgren and Isabel Ahlgren
In the days of the voyageurs, branches were cut from tall trees along the Minnesota-Ontario border, leaving the middle of the trees bare. These "lob trees" served as guideposts, helping fur traders and explorers find their way through the uncharted maze of lakes and portages.
The authors of this book are retired forest ecologists who worked for many years at the Wilderness Research Foundation in Ely, Minnesota.
