What this means before you buy
Sinkholes are uncommon here; watch for new depressions after heavy rain or leaking pipes.
That works out to roughly 170 of Kanabec County's 522 square miles on soluble rock. With about 16,608 residents (32 per square mile), much of the land is open, and the mapped rock may sit far from where people actually live. The figures come from 323 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.
