TRINITY'S 3rd annual 2012/2013 icing challenge

I haven't done a ton of research on Mille Lacs but at first glance, I would say Isle Bay looks good from the contour maps... There is a 36' deep trough that runs NW by SE that is not very wide. It drops from 15' deep to 30' deep within 30' lineal feet along the SW side of this trough for quite a ways. This should be all large boulders in the area per the reports, but nothing confirmed.
Here are coordinates to some possible dive holes 301' from each other that are each centered on the 15' deep "top of the trough" from the Northern most to the Southern most:
N46 08.922' W93 28.782'
N46 08.884' W93 28.735'
N46 08.845' W93 28.690'
N46 08.814' W93 28.636'
N46 08.773' W93 28.594'

There is another nice little submerged peninsula across this narrow trench that is exactly 300' from the last coord shown above. This coord is also at the 15' deep mark:
N46 08.753' W93 28.530'

This is as far south on Mille Lacs as it gets for any "good structure". Generally the South half of Mille Lacs is rocky. The NE quarter of Mille Lacs is sandy gravel, and the NW quarter is mud. There is another area that somewhat interests me on the East side nearer to the North end of the lake called Agate Reef near Agate Reef Resort. This one is a 1.15 mile long narrow submerged reef that runs from N46 17.815' W93 32.486' at the NE end (closest to land) to N46 17.028' W93 33.349' at the SW end of the reef. This is a large, long area that would support many divers in many holes over many days but the possibility of good structure is less promising as the rocks should be much smaller up here than the Isle area.
