 Inferno Cone Viewpoint ( photo ) is on top of Inferno Cone cinder cone . A short but steep trail up the cinder cone leads to an overlook of the entire monument . From there the Spatter Cones can be seen just to the south along with a large part of the Great Rift . In the distance is the over 700 @-@ foot @-@ tall ( > 200 m ) Big Cinder Butte , one of the world 's largest , purely basaltic , cinder cones . Further away are the Pioneer Mountains ( behind the Visitor Center ) and beyond the monument are the White Knob Mountains , the Lost River Range , and the Lemhi Range .
