When Hart made this picture in the summer of 1868, workmen were finishing a stone retaining wall just west of the tunnel mouth. The wall was for protection from snow slides. The Chinese workers slept in log cabins and huts made out of shakes. Some cabins had bunks for several men, but others were only four feet high, six feet wide, and eight feet long—little more than wood lined snow caves. An avalanche killed from 15 to 20 workers near this spot in February 1867.
