Looking up the cut from Bas Obispo

Pennell, Joseph, 1857-1926 · 1912

"This drawing shows the cut and gives from above some idea of the different levels on which the work is carried out. It is on some of these levels that slides have occurred and wrecked the work. The slide moves slowly, not like avalanches, but have caused endless complications; but Colonel Gaillard, the engineer in charge, believe he will triumph over all his difficulties - which include even a small volcano - there is newspaper story - but no earthquakes." Joseph Pennell.
