Farmer finds rare meteorite on field near Arlington

Farmer Bruce Lilienthal has a favourite saying: "Rocks are a crop we always harvest, but never plant."
He shared that joke Wednesday as he sat in the kitchen of his Sibley County farmhouse, explaining that each spring before planting, he gathers large rocks that frost has pushed to the surface before they can damage his tillage equipment.
Lilienthal saves unique rocks in a pile near his driveway, but one in particular is especially unusual.
It's a rare meteorite, at 4.6 billion years old - roughly the same age as our sun - and one of only nine or 10 that have been confirmed in Minnesota since European settlement.
