MINNEAPOLIS — In the Land of 10,000 Lakes, one beach in northern Minnesota stands out. While most of Lake Superior's iconic shoreline is gray rock, this stretch is a surprising pink.
Many North Shore visitors likely skirt past Iona's Beach as they zip by on Highway 61 en route to popular waterfalls and some of the most visited state parks in Minnesota. But those who veer off the beaten path find salmon-colored pebbles and a serene spot to take in the largest of the five Great Lakes.
"It is a relatively unusual composition of volcanic rock," says John Green, a retired Duluth professor who wrote a book on the geology of the North Shore.
