Explore North Dakota

Western North Dakota's reddish rock layers are clinker, locally called scoria, formed where seams of lignite coal burned and baked the nearby sediments into a natural brick. Because gravel is scarce in the southwest, the North Dakota Geological Survey says clinker is commonly used as road metal there, so the rock that colors the hills also surfaces the roads.

Around 16 breweries sit near the stops we cover in North Dakota. 6 of them are brewpubs with a kitchen, which off the motorway is often the useful part. The kitchen figure is a floor: the source lists some full restaurants as production sites.
