Essential to hydraulic performance of a dry-stack wall is backfill with heartings, which compare to ballast. Oh no. The DSP&P did not use ballast at Como, or on Boreas Pass. Luckily, the stacks at The Palisades had all the heartings they needed thanks to the Alpine Tunnel. [Thanks to John Meixel]
So this wall and this wall don't look a lot alike but they were within a milepost of each other. Why so different?

There were 2 main construction companies mentioned, the way I read it the above was responsible for the first 150 mile section and then the Denver and South Park Railroad Construction Company took over.

I had also read and forget where that this was a common way for the early investors to make their money no matter what happened, essentially the returns from construction covered their investment.

I cannot prove it just my impression was that these Construction companies did not employ the labourers etc that would have built the grade.

If we want to go back further there were several predecessors:

Denver Railway Association
Denver Railway and Enterprise Company (- Morrison branch)
Denver and San Juan Railroad Railroad Construction Company

In 1875 they were dividing the line up here Buffalo Creek to Halls Gulch to Fairplay to Salt Works to the mouth of Trout Creek.
