Today is the 135th anniversary of John Frank Stevens and his Native American guide Coonsah hiking over what is now Marias Pass on the former GN transcontinental railway. At elevation 5,213 feet this is the lowest point on the Continental Divide across the Rockies in Montana.
Learned this today from Dr. Joseph Lechner courtesy of the TCA TTML.
My only experience with Marias Pass was on Microsoft Train Simulator and trying to get a BNSF freight train into a passing siding before an oncoming train arrived. It did not go well for me. If @Number 90 had been my supervisor, I would have received many demerits, a likely suspension, and other disciplinary action for my lack of applied skill on this incident. 
Amtrak still has a station stop at this location just south of Glacier National Park.
