What a wonderful book. I just acquired what was a library copy for $20 through Amazon. I know some railroad aficionados who would enjoy the Great Northern photographs on page 66. The photo on page 67 is dated as August 9. If so, they are not crossing the Rockies, but are crossing the Cascades. Pond makes the same mistake in his notes on page 11. I have a note that the train stopped for a short time "a short distance from Wellington for about 5 minutes" and that they rolled rocks down a precipice. This is likely at a stop known as Ebro. The photo certainly looks as if they are standing on the edge of a precipice.
