Why this stretch is hard in winter
- Marias Pass sits on the Continental Divide, so the east side (NWS Great Falls) and the west side (NWS Missoula) are forecast by different offices.
- There is no nearby paved alternative across the Divide: Going-to-the-Sun Road through the park closes to cars in winter.
- MDT 511 is the official source for closures and road conditions on this stretch.
