Buster’s Quad D9s were the star of the show on the $20 million spillway. Excavation of some 4 million cubic yards of solid rock made it one of the biggest ripping jobs in the West at the time. One million yards of that material had to be ripped using various methods, including Peterson’s new Quad D9 arrangement, outfitted with two 10-ft shanks, each with 4-ft extensions.
Nope, no WAY that formation could be called FOLIATED, what a dumb proposal on my (and the USGS's) part.
Ripping "Igneous basalt" is a real common practice, it's easy...no ?
