On a spring day in the early twentieth century, a common snapping turtle (
Chelydra serpentina) hatches near
Little Elk Lake in Minnesota's
Itasca State Park. Soon after emergence the hatchling is hit by a stray bullet from a
poacher's gun, amputating her left rear leg. She is then captured by an
Ojibwe (Chippewa) boy who provides a protective pen in the lake where she can recover. The boy decides that the three-legged hatchling will have a difficult time surviving in the competitive ecosystem of Little Elk Lake, and takes the turtle with him when he accompanies a ranger from Itasca State Park on a trip into the headwaters of the Mississippi River. He paints the word "MINN" on her carapace and releases her into the Mississippi some 100 miles downstream from her birthplace. Holling explains that Minn's missing back leg means that she can't "bottom-walk" upstream against the river's current during spring floods. Over the ensuing twenty-five years the turtle, destined always to move downstream, travels the entire course of the river. At times she moves away from the river or is deposited by floods in a tributary, swamp or pond, but she is always drawn or pushed back. Minn's encounters with other animals, people, and the natural and human environments through which she travels allow Holling to discuss the
ecology,
geology,
geography and human
history of the river, as well as the
natural history of snapping turtles. The narrative shifts among observations from Minn's perspective, explanations and descriptions by Holling as
omniscient narrator, and dialog provided by the various human characters Minn encounters. Minn is captured several times by people intending to fatten her for the table, including a white family living in a
shanty boat in the river north of
St. Louis and an African American family living near the river south of
Memphis. She always escapes from captivity or is freed by friendly people, but these encounters, along with her interactions with fishermen, hunters and tourists, enable Holling to illustrate the varieties of human life along the river and the people's attitudes towards wildlife and nature. Minn eventually travels through
New Orleans and reaches the Gulf of Mexico. She is swept into the Gulf and out to sea by a gale, and lands on a "sand island" in
Barataria Bay. She is captured one final time by a pair of
Cajun fishermen and taken to New Orleans for sale. A woman pays the fishermen to take her into
Bayou Barataria and set her free. As the story ends, Minn is living among lost pirate treasures in the bayou. She encounters two more boys: first, an angry Anglo boy who tries to hit her with his boat pole, ranting about how the world looks down on him for being poor and what he would do if he had a million dollars (even as his pole is hitting the gold and jewels buried in the mud), and finally a Cajun boy who has the book's last word, expressing kinship with Minn as a fellow creature sharing a free life in the swamp. == Context ==
