Amazing technology.
A viking long ship and a number of burial mounds have
been found next to a busy freeway in Norway using a
motorised high resolution Georadar.
you can watch it with commentary on
abc news just in.

Vikings are an interesting lot,
Harald Bluetooth for one, which modern
Bluetooth technology is named in respect
for Haralds part he played in trying unify
Denmark and Norway.
