SPLIT ROCK LIGHTHOUSE STATE PARK
North Shore Abrasives wasn’t the only company to mistake anorthosite for corundum. The Country Abrasives Company (MAC), now known as 3M, had corundum mine sites further up the North Shore in what are now Tettegouche and Temperance River state parks. In Two Harbors 100 Years, the story is that they made only one sale of their product. In March 1904, MAC sold one ton of corundum to Champion Corundum Wheel Company for $20. When MAC learned that what they really had was anorthosite, they kept it a secret from their investors long enough to turn to making sandpaper in Duluth in 1913. The rest is history as they say for this small company was able to recover from its false start.
The anorthosite outcropping at Corundum Point is a miniature version of the massive outcropping known as Carlton Peak in Temperance River State Park. While not the hard corundum many thought it to be, this rock is resistant to erosion. All glaciers have been able to do after repeated passes is shape the outcroppings with smooth curves. Take care on the summit of Corundum Point as the smooth rock slopes steeply towards cliffs on Lake Superior.
