Think what you experianced was Aurora E with multihop something...
It is quite common ove here in Scandinavia that we get Aurora, if it is a 
strong Aurora workable all the way down on 10m we can work pretty much all 
of Scandinavia, Murmansk, Scotland etc but when the aurora fades out we can 
get lucky to get what is called Aurora-E.
I am not sure exactly how it works but it seems the waves bounce on the 
Aurora as a reflector and gets a very low angle over the north pole and with 
a little help from a E or a F-layer on the other side we get to work Alaska, 
Washington, californa and around that neighbourhood.

What is interesting with 10m is that 12 and 15 can be completely dead but 
10m is open, now how is that? Same with 6m.

I think a good beacon to know if there is propagition on 10m is to listen on 
11m. 27.555 USB - there is almost always activity and by the prefixes you 
will know where the call is from.
