The driving of a final spike in Ashland in 1887 completed the railroad line running up the West Coast.
But the project took a few shortcuts along the way, and the evidence of options not taken are still out there. Like Buck Rock Tunnel near Ashland. Crews drilled 300 feet into the rock and stopped, in favor of a different tunnel across the valley.
Buck Rock is the focus of this month's Underground History segment with our resident archaeologists, Chelsea Rose and Mark Tveskov.
Lisa Rice of the Bureau of Land Management also joins us to talk about the forgotten tunnel in the hills.
