They were flying east north east which did not seem unusual to me at the
time. Now I am scratching my head.

Perhaps they decided weather was unfavorable for crossing the pass. All of
the adults in the flock have been there before. I've been wondering a bit
lately how these social birds achieve consensus. Will we ever know?
Thanks for the cardinal clarification Steve. Otherwise I might
have assumed the reversed direction was a clerical error. Jack Williamson
saw(I left my glasses at home)some GWFG that I heard over West Linn at 4:15
Saturday. I presume they were southbound as he made no comment otherwise.
It seems like it has been 8 days since that last big wave. The ones folks
notice the last week of August(I think reports began as early as 8/20 this
year) nest on the Alaska Penninsula. That is to say the south shore of
Bristol Bay. Thanks to satellite tracking we now know this subset of
Alaskan GWFG will slow the pace of migration a little after resting in the
Klamath Basin, but not finish their annual cycle until reaching Chihuahua.
Later in the winter they are back in the Central Valley. The GWFG passing
over nw Oregon a month later nested on the north shore of Bristol Bay.
Maybe today's geese are from a third location in Alaska.

In my first post, I should have noted that the geese I heard were flying
in the opposite direction that you'd expect, for this time of the year. I
have no explanation for that.
