Just trying to make it possible for others to replicate the exciting voyage of discovery as much as possible within the vacuum of the human mind 

so for those w better PC shills or skills you might be able to post a better representation of what I'm displaying-unfortunately I dont think the 50k scale w poor resolution gets down to the mine

but I didnt check all the various sub series of maps to see whether any such sub series had better coverage -just automatically selected for magnetic maps -as pertinent to iron-oh well, as Paul Newman said in "Message In a Bottle" ,  'theres always tomorrow ''

questions? requests? outrage? or just mind numbing stupor?
