Ghost Towns In Eastern Washington?

Doing some researching work lately I've come upon some towns that aren't "alive" any longer. Methinks they've turned into Ghost Towns??

I'm talking about Beverly and Bong and Fletcher and Brents, all in eastern Washington. Beverly must be a real place because I did find this:

Further looking and I found that Beverly was named about 1905 by H. R. Williams after Beverly, Massachusetts, and in its day (1905-1920s) our Beverly was home to hundreds of railroad workers.

But of Brents (Lincoln Co), Fletcher (Adams Co) and Bong, I found nothing. And believe me you get many interesting results when you search for "Bong Washington."

Did find two most interesting websites regarding ghost towns in Washington:

ghosttowns.com/states/wa   and  ghosttownsofwashington.com

Maybe you will come up with some information on these towns or other long-lost towns of Washington?
