"During the season over 1,200 miles were traveled in moving the main camp by wagon and pack-train. Well-balanced quadrilaterals were obtained with triangles having sides from 30 to 65 miles in length.
It was found that a well-built cairn 10 to 12 feet high made the best target. On all the peaks there was found an abundant supply of loose rock sufficient also for shelter-walls, which were sometimes needed to prevent the transit from being blown over by the gales.
Flags, even when made of stout duck [a kind of heavy cloth], had a very short life owing to the persistent gales. They were effective only for about three weeks."
