In , Michael Sherwin locates and photographs significant sites of indigenous American presence, including sacred landforms, earthworks, documented archaeological sites and contested battlegrounds. The sites he chooses to visit are literal and metaphorical vanishing points. They are places in the landscape where two lines, or cultures, converge. They are also actual archaeological sites where the sparse evidence of a culture's once vibrant existence has all but disappeared. While visiting these sites, Sherwin reflects on the monuments modern culture will leave behind and what the archaeological evidence of our civilization will reveal about our time on Earth.
