Mollie Adams Diary of her Journey in the Canadian Rockies, September 11, 1908
Friday, Sept. 11.
Off at 9 A. M. 5½ hrs. to Flats Camp. Had expected to camp at the big meadow just below the quicksands, but it only took a little over two hours to get there, so had to keep on the Flats, the next feed. Perfect weather, frost last night, bright sun all day and not a cloud in the sky. Very peculiar and brilliant northern lights, starting with a bright streak right across the sky to the south of the zenith, with short, thick rays from it converging toward the magnetic north. Then all kinds of rays waved over the sky for more than an hour, finishing up with a sort of film over everything so only the brightest stars were visible. Then at 8.30 the moon (full last night) came up, and this show was over.
