A fleet of 1930 Packer-like busses called “jammers” were rebuilt in 2001 to run on propane or gasoline and offer tours to the top for those without transportation, are driving a motor home (too wide) or the expertise to drive the narrow and winding two-lane road.
The road has been designated a National Historic Landmark and Historic Civil Engineering Landmark…so good luck in getting any of the 53 miles widened!
It is one of the most difficult roads to snowplow. Up to 80 feet of snow can lie at top of Logan Pass. It can take up to ten weeks to plow even with equipment that can move 4000 tons of snow in an hour. On the east side of the continental divide there are few guardrails. The late winter avalanches have repeatedly destroyed every protective barrier ever constructed….hence the 25 to 35 MPH….don’t look down if you are afraid of heights.
We only covered one side of the mountain up to Logan’s Pass due to the summer’s second forest fire. Prior to the construction of the road, it would take earlier travelers 3-4 days to cross the summit.
