Up go the mountains....
Using foam, the backbone of the surrounding Allegheny mountains has been formed. Before any work was done, all of the track was removed to prevent any mishaps. Each section was layered and attached to the former by hot glue, and then sliced at an angle (to create the appropriate slope) with a hand-held dry wall saw. Once this was completed, tan paint was applied to cover all aspects of the mountains. Another task that was performed was cutting out the lake bed of the first Kittanning Reservoir, with the outline of the second Kittanning Reservoir only drawn by black marker.
Here are two photos below of the current progress on the mountains; next step is adding scenery.
