Scott Conarroe's large-format photos evoke romantic pictorial traditions and locate the present within a sweep of history.  His series By Rail and By Sea look at railways and the coastal perimeter of the US and Canada; they depict the westernmost front of Western Civilization as a vast bloc of Cold War superpower and British Empire outpost. The Great Eastern considers China against the backdrop of a massive railway expansion.  And Frontière, Frontiera, Grenze looks at the movable borders four Alps nations negotiated in response to acute glacial melting and watershed drift.
