And oldie but a goodie. Going through some archives and re-processing unpublished work. Description The Devil's Slide was the site of a military triangulation station and observation post used during World War II as part of San Francisco's harbor defense. Before radar was developed, military personnel used binoculars and compasses to search for ships at sea and report their coordinates to a central location. By combining information from multiple observation posts, a ship's precise location could be determined through triangulation. There were six military structures at the Devil's Slide: three concrete and steel observation pill-boxes, two concrete and earth bunkers, and a reinforced steel observation tower. The pill-boxes served as hardened observation posts, and one of the bunkers was used as a communications and command center. Technical Notes: For use with Unlit shader in Unity - import instructions
