How covered wagons traversed the Rockies

In old western movies, the settlers' covered wagons are typically shown traversing the plains and deserts.  Getting them over the mountains was less scenic.

The illustration above comes from an outstanding book - Hard Road West, by Keith Heyer Meldahl - that I'll review in more detail later.  It shows the technique used at a location eventually dubbed "Roller Pass."
At Roller Pass, the final 400 feet from a 30-degree slope of jagged boulders, "as steep as the roof of a house"... Oxen could not pull wagons directly up such a grade.  Instead, the animals were unhitched from the wagons and driven to the top, where they could heave along the flatter ground at the pass.  Some emigrants placed log rollers at the top of the slope.  They yoked the oxen to hundreds of feet of chain, and then passed the chain over the rollers and down the slope to a waiting wagon.  Then, under shouts and cracking whips, as many as 12 yoke of oxen hove to on each wagon..."
The drawing doesn't seem to be to scale re the wagon, but the point is clear.  At other sites, the terrain was even more impassable, and the wagons had to be unloaded and disassembled, and the wagon parts hoisted up the mountain with winches, then reassembled at the higher altitude.

  1. In the recent movie Meek's Cutoff, there is a scene were they are lowering three wagons down a steep hill, one at a time. Let me just say those wagons are pretty brittle.

  2. You've really got to want to get somewhere to go through all of that. Which is how Denver came to be.

  3. Denver came to be because of the gold in Cherry Creek

    1. There were no roads back then. The mountains were nearly unused by anyone, trails were few and far between, and many times, they were wrecked by falling rocks. On top of that, the trails were muddy and rutted in. Plus, many times, they were on the trails, through those passes.

  5. The log roller would reduce the friction considerable, sort of like a sheave in a pulley, although it would be more akin to a "Dead-eye" than a modern pulley.
    Amazing the effort they went to, did they leave the chains there for the next group?
    Up here enterprising individuals would set up equipment to ease the passage at choke points like this, of course it would cost the user a fair bit. Most people who got rich in the gold fields were the ones supplying equipment and services to the miners.

  6. I have driven through the Rockies many times. Each time I look back to the West, to the row after row of precipitous mountain ranges, and ponder how my ancestors managed to get their kids to walk all that way, and over those mountains. After the first month of, "Are we there yet?", I'd probably have strangled them.

    Actually, if I were faced with trying to get a wagon over one of those mountains, I'd ask Kit Carson to found a route around -- quick!
