Mapping around Threshold
by happylarryI know some work has been done on mapping the threshold area elsehwere - but I wanted to share what I've done for others to comment.
Basically, I've tried to convert up the 500' hex map from the expert set (1983) of Threshold to 2/3 mile and 2 mile hex
let's see if this works first of all:
basically, the red hexes are 2 mile, and the grey ones 2/3 mile (=7 500' hexes from the original map)
