The Boston Mountains are a high and deeply dissected plateau in northern Arkansas and northeastern Oklahoma where they are referred to as the Cookson Hills. The Bostons form the southwestern part of Ozark plateau of which they are the highest and in general most rugged. The rocks of the region are essentially little disturbed, flat-lying sedimentary layers of the Paleozoic age. The highest ridges and peaks are capped by Pennsylvanian sandstone and shale. The deeply eroded valleys are cut into Mississippian limestone and below that layer the Ordoviciandolomite. Image File history File links BuffaloRiver. ...

Topography is mostly gently rolling, except in the BostonMountains, along the escarpments separating the Springfield and Salem Plateaus, and the Saint Francois Range where it is rugged.
The Saint Francois Mountain Range rises above the Ozarkplateau and is the geological cause of the highland dome.
The igneous and volcanic rocks of the Saint Francois Mountains are the remains of a Precambrian mountain range.
