@minelifemediallc: Minnesota's North Shore is an epic drive along mid continent rift geology! But aside from geological stories, there is also some cool human history too! The famous 3M brand started as a mining company, trying to mine the hard mineral of corundum (which is the mineral name for gems like sapphires!). But, they were actually mining a different, softer mineral. Talk about a rocky start!! Learn more in the full Roadside Geology of Minnesota's North Shore video on The Rock Record! ▶️ #Minnesota #Geology #History #LakeSuperior
