"She is amazingly intact," Tom Swerski, the Field's project manager for the exhibit, said last fall.
Monday was Lyuba's last day on display at the Field Museum.
She's now headed to the Liberty Science Center in Jersey City, N.J., as part of a tour that will take her to Alaska, California, Colorado, Massachusetts and Missouri.
A reindeer herder in northern Siberia's remote Yamal-Nenets autonomous region found Lyuba in 2007. The 45-inch long, 92-pound mammoth is named for his wife.
