Kelly, 43 years ago most of the entire transverse had large areas of silt in some places 2-4 feet deep. The cave between P1 and the start of the peanut tunnel looks absolutely nothing like does today. It used to have deep silt in many places. Today you can see all the exposed limestone. So I agree with your conclusion.
