As of 11-21-2011, many areas of Mt. Hood National Forest received snow down to the 1500 foot elevation making many forest roads difficult to navigate. The public should check with local Forest Service offices before embarking upon any excursion to the woods. Many areas are becoming impassable or hazardous due to the presence of snow. Snow is not plowed on national forest roads and forest roads are not maintained for winter travel. Navigation gps systems directing use of national forest roads do not consider that roads are narrow or can be closed by snow. Motorists should be prepared.
