The Central Pacific recorded forty-four storms in the winter of 1866 to 1867, and Chinese crews lived and worked in tunnels beneath the drifts at Donner Summit. When avalanches took whole camps, the company kept payroll ledgers but none of the dead. The episode covers the June 1867 strike of roughly three thousand workers, broken when Crocker cut off their food, and Promontory Summit, where Chinese workers vanished from the famous photograph.
No death ledger for Chinese workers exists. Estimates range from about 50 to 150 on the railroad side, to hundreds and possibly up to 1,200 in the Stanford project, to outlier figures above 2,000.
