Sort of the ugly stepdaughter: Lumpy on the left side, a gouged-out “hole” - old blown-out side crater maybe?) on the right.
Not a well-known mountain.
I know! But it's hard to miss from Mount St. Helens:
This is from the rim of St. Helens (a place I've never been), but you can see Mt. Adams quite readily from the Visitor Center, a place I've been to twice, once before it was built and once after.
