Hard to tell right now but probably as large as the area that was being worked since last September..
The road is gone ! ( road rage again) Richard has removed about 2 feet of the top soil so at least 150' X 20' 0f productive area is available...A certain Flint professor whos' name begins with 'Jessie' thinks a more major camp is located farther uphill.
Very logical as it is more at the intersection of the small drainage with the main creek and it will have had far less flood washout from the big creek.
More trenching for better access was mentioned.
