Black holes have mystified astronomers for hundreds of years.
The one found in North Long Lake in Brainerd, measures 2,128 feet
in length and 400 feet wide. It has been the talk of Minnesota
The hole was first seen in February, 2002. There has never been
open water on this part of North Long before. Ice depth around
the hole ranges from 4 to 10 feet. Many have been trying to find
the answer. Divers have gone into the hole, infared aireal photos
have been taken and much research has been done - all to no avail.
