We are entering that time of year when adventurous Minnesotans start answering the call of the Boundary Waters, the pristine and isolated land and water we love so much in this state.The Boundary Waters has seen an increase in visitors over the past few years, likely due to the pandemic. Regional journalist and paddle enthusiast Joe Friedrichs wants those visitors to remember that this beautiful northern landscape comes with its own hazards and potential dangers. On Tuesday, he will release a book filled with true stories of peril in the area. Friedrichs joined MPR News host Emily Bright to share what he learned while writing “Last Entry Point: Stories of Death and Danger in the Boundary Waters.”
