Beacon Rock in Washington State is a volcanic neck, perhaps not as striking and unique as Devils Tower in Wyoming, but pretty much the same thing geologically, if not mineralogically. (Not sure what mineral/rock Beacon Rock is made of.) Beacon Rock is one of the striking landmarks on the Columbia Gorge
It's also right next to the road on one side of the Columbia River, and visible for long distances from the other side (though as I discovered, trees can block the view from much of the main road). I grabbed three separate views of Beacon Rock, shown below. I've been by there once, and it stands out.
