In Season 3 Episode 5 "Search and Recover" When Weaver and the group search for Anne they come across a women dead on the steppes of a building, The building is actually an abandoned state asylum in Georgia. No where near Charleston SC.
Charleston, SC does not have mountains or forests. It has pine trees but not like the ones seen here. The scene of Tom and Pope in the woods looks similar to Endor in Return of the Jedi.
