Green Island Preserve, Wadena, Minnesota located in the northern 1/3 of the state . The vortex was identified by two different geomancers using two different methods. The photo shows the approximate center but it is unclear just how large it is. One warning was that pine trees would not fare well in such a vortex. Several nearby pines have been showing illness, decline, and even death. No one has yet spent any prolonged time in this vortex and therefore there are no descriptions of it effect. – Kent
