Drumland swarms show radial orientation converging on Lake Ontario impact point. Eastern drumlins oriented northwest Drumlins transition to north-south orientation moving westward Drumland trajectory converges at same point as Finger Lakes

Drumlins across the eastern US shift orientation—from northwest to north-south as you move west—but their trajectories ALL converge at one point: Lake Ontario's deepest basin. Even the lake floor shows elongated drumlin-like erosion patterns. The geometry suggests drumlins across a massive region recorded the same catastrophic event.

Key Facts

  • Eastern drumlins oriented northwest
  • Drumlins transition to north-south orientation moving westward
  • Drumland trajectory converges at same point as Finger Lakes
  • Convergence point coincides with deepest part of Lake Ontario
  • Lake floor shows drumland-like erosion patterns but elongated
