Bear den elevation

[Pizzle12345]

I am curious if there is a standard location for bear dens.  From google searching it seems like it depends on what state and geography so I am asking specifically for western Washington in Snohomish county and north and for the Idaho near Spokane.   My best guess would be that the dens will be closer to rivers and streams in the trees and not at higher elevations.  But I am writing this post to see if people in these two areas have similar experiences. 

I think these areas should have similar terrain.

I know of multiple bear dens in the north central part of the state ranging from just over 1K to just under 6K in elevation. I personally think more winter in what I'd call the mid elevations.

There were a number of dens around my old cabin, which was about 2600ft and just East of Snoqualmie pass.
