This portal faces "north" with Binghampton in staging being to the right. It was tough to disguise due to the limited clearances against the wall. So it's a "blasted" rock portal, with the rock work above the SBD covered hopper being Sculptamold applied directly to the wall. Woodland Scenics clump foliage was glued above the rock with silicone sealer, along with shrubbery, to give a more 3D look and some depth to the flat. This mountain covers a major 90 degree bend in the plumbing drain above the tunnel liner.
