Ed,
The original map was drawn, I'm pretty sure, by Paul, K4UJ. I was club
president at the time the circle was drawn and have a paper copy of an
email Paul sent regarding setting it up. He says in part:
"I have a formula to calculate the distance between two sets of latitude
and longitude coordinates. It is possible with a little tinkering to
figure out the best CENTER by using the formula to calculate the
distance. etc. . . " That's about all I have on the subject of how it was
drawn.
One of the reasons the circle was positioned so far to the north was so
that it would include AA4S, who was very active at the time.
FYI.
