I have recently had the good fortune to be entrusted with some old climbing photos from Canada, specifically of the Bugaboos and Mount Robson. The Bugaboo photos were taken in July 1973 by Charles Calef. The Robson photos were taken in 1968 by either Dave Brown or George Bell. The modern photos are mine. The pairs aren’t perfectly matched, but they’re close enough for comparisons.
The modern photos are from early August, 2014.
The modern photos are from mid-July, 2017. There’s no way I could have day-hiked the Kain Face in 1968, even if the Thoni Trail had existed.
