This collection of photos shows parts of the Black Hills National Forest and of the Custer State Park. My travelogue report for this day can be read here.
The following map shows the route I took from Keystone, SD to Mount Rushmore, on the Wildlife Loop through Custer State Park and back to Keystone.
The following photos were taken while riding along the Wildlife Loop road in the Custer State Park. Since the bison were mostly grazing the presumably succulent grass, these photos show mostly just their backsides. In some of the photos calves can be seen with their light brown coats of fur.
