Imagine waking up to the sun cresting a ridge of the Cascade Mountains. You look out the window, and through the dawn light you can see clouds still settled over a lush alpine forest. You’re in a tower in the sky, in the shadow of our tallest peaks, surrounded by wilderness. Camping in a fire lookout tower is like no other experience in the Pacific Northwest. …But booking a night in a fire lookout can be harder than getting a ticket to “Hamilton,” thanks to high demand, short supply, and prices from $35 to $65 a night. Of the hundreds of lookouts in Oregon and Washington, only 22 are available to the public. …As technology makes fire lookouts obsolete, federal and state agencies are stuck with the question of what to do with the towers. Should they be turned into vacation rentals? Torn down? Preserved in public parks and museums?
