Guided questions and answers describe who blazed the Oregon Trail, why and where the trail began, life along the trail, where the emigrants settled, why people stopped traveling the trail, and how today's
historians know about these experiences.
Historian Deborah Willis says of Walker's work and Kamoinge, «The photographs are a rich contrast to the «headline» images that have circulated worldwide
about black communities
known only as the roughest and toughest neighborhoods to live in... I consider these photographs to be a mosaic of the black
experience; they expand our consciousness and challenge what we think we
know about black life.»
