never thought of the base, i lived there when my father was stationed there,in the early 70's .last sumer i started exploring for some of the gold mine on the dead river basin range about 10 miles east of the ropes, there are about 25 gold mines in this area, thats why I'm looking at the t-2 or a mxt' some of negaunee's old caving grounds are suppose to open back up for redevelopment this summer, where the houses where relocated.this started back in the 20's through the 70's, but don't know what kind of depth ill get with the iron ore, did some last year but found little including trash, using a qxt, logging camps and saw mills, haven't done this yet , suppose to be a big one 2 miles up the road from my folks place, what Ive concentrated on mostly are the old charcoal kilns from the 1860's to 1900, talk about old iron and steel, the made charcoal for the blast furnaces for the iron mines. thanks for the response Pete oh ya talking about fire the great peshtigo fire happened here at the same time as the great Chicago fire ,but they lost more people up here
