Have you turned on the real-time weather? I know Minnesota is a real freezer in Winter and I’ve experienced -30 in Celsius there. My photos were taken before the last update and that’s why the earth was so green in spite of it was in December. The spike will grow as you get closer. When I tried climbing up to the top, the height became 7,000 feet and more. Nearby is one more spike. You can easily find it if you fly along the Mississippi to St.Paul from Redwing.
