 In the early 1950s John Goggin and his students from the University of Florida collected potsherds and other artifacts from the ground surface of the middens and other areas surrounding the Mount Royal mound.By this time the avenue reported by the Bartrams and Moore was no longer visible from the ground, but did show up in aerial photos.With the area slated for residential development, B. Calvin Jones of the Florida Bureau of Archaeological Research conducted investigations in 1983, 1994 and 1995, including shovel tests and focused excavations of selected areas.
