Great pics of the Yeager spread. I have seen a great many of their jobs around here. Shame to see the name gone away now that they were bought out by Skanska from I believe Sweden.
If you look closely at the pice from the hiltop cut, you will see the old 641 stiff hitch scrapers are working in the rock cut in the center, with the D-9L pushcats to get better power to the ground, and the newer 651B's, 651E's, and 657B's are working the better dirt on the perimeter of the hill, with the older D-9H or G pushcats. Those old 641's spent most of their life stuck in the rock somewhere, and they were pretty rough as a result, but they ran steady.
