Thanks to Dan Baccus for the correction on the sightings of Great Gray Owls.
I should have stated more precisely that I knew of no sightings within that
portion of the Blue mountains that is within Washington, which I gather was
the context of the original query. The comment leads to the added point
that the La Grande, OR region is of the same order of distance from the
region in question in Wasshington as is Winchester, ID. John Hirth
