Bill Barse, a reader who gave us a comprehensive tour of Arkansas, Tennessee, and Virginia, sends an image from amid “the endless expanse of sugar cane fields south of Lake Okeechobee, Florida”:
There were relict streams that once drained into the original Everglades that are now submerged due to sea level rise that took place over the last 2,000 years. Many archaeological sites, low-lying mounds, are present along these now submerged streams, sites that we were working on at the time of this trip. The area south of the lake is a low-lying plane with limestone bedrock barely two feet beneath the current ground surface. And it is only several feet above sea level. This picture shows a good view of a 2,000-year-old house mound located not far from one of the relict stream channels. One of the access roads for the sugar cane fields made a U-turn around it to avoid its destruction.
Bill flew all the way from East Stroudsberg, Pennsylvania, on this trip, and the archaeological sites near Clewiston, Florida, were his final destination. He also documented more recently built structures, from highways to horse tracks:
