I am planning to visit GNP this weekend (October 10-12). However the weather shows snow/rain and really low temps. Columbia falls show cloudy and Browning shows rain/snow of 2 in. What will this look like in terms of accessibility and will the going to the sun road still be accessible if there is some snow? I am assuming that a long hike like Grinnell glacier or Iceberg lake is out of the question?
