That's comparing foot transport to wheeled transport. The point there is that wheeled downhill causes squat erosion.
The reference is familiar - it's used to counter people who bitch about downhill mountain bikers.
For wheeled, it's going uphill that causes much of the erosion.
For foot, greater force going down is mitigated by fewer steps. There's no magnitude difference between going up and down.
Downhill traffic is a spit in the bucket compared to all those people going up the BCMC and down the gondola.
Grouse Grind was fixed by putting in stairs. Back before they had em, you had to keep looking up for the rocks being kicked down by people going up above you. I've been hit by more than my share.
Seriously, you're blaming the small population of people, some of who's been hiking those trails for generations, for a problem they didn't cause.
