interestingly
this lesser bit of rive gauche delaware was not the direct result of
such an avulsion as killcohook was
nor could accretion ever create any left bank delaware either
rather it was merely an accident of the belated backswing
following the 1934 supreme court decision
of the same 12mile new castle arc that has caused delaware to
have a round top since 1683
& it is precisely upon this lesser of the 2 dry denj segments that
denj shifts from the jersey shore to midchannel
along this recent sequel to that ancient arc
cutting off a preexisting but artificial protruding tongue of land
a very funny thing
& it all seems to have just happened by chance
yet this sweep of 12mile arc was in fact badly mismeasured
it would be a good topic in itself for further research
the artificial island obviously predates the 1934 demarcation

& please zoom out from there to get your bearings if necessary
i couldnt find denj marker artificial 6
tho i did find several of its mates
of course i had to sneak in & out so it was kind of touch & go
