Foot Prints . . . Across the Divide

My footprints are faint and maybe fading, but they cover much of the Atlantic world . . . beginning somewhere in Viking England
with a rebirth on the Eastern Shore in Maryland
and ending somewhat south and west until . . .

oddly, from somewhere in Texas and New Mexico
they also cover the Pacific coast (another universe):

From San Francisco to the Apple Orchards of the Okanogan Valley . . .

Obvious places to begin and end . . .
east to west,
across an invented, mostly conquered divide . . .
