Leopold Amery, in his book "In the Sun and the Rain, describes his visit to the pass as follows, "Passing Watchman Lake, a large sheet of lovely greeny-blue water, we reached a pleasant alp forming the top of the pass. Here Edward (Edward Feuz jr.) and I brewed tea by a little lake called Cinema Lake. Watchman and an immense mass of snow-banded rock, Spring-Rice, on the one side and the mighty crest of Bryce on the other, towering over us -above the dark slender spruces -were again mirrored in the lake at our feet. As we rose we flushed a magnificent eagle. From Thompson Pass, a track cut by Wheeler years ago and not used since, led down into the valley of the Rice Brook. This we followed, not without difficulty in places, to where it came to an end at the head of a steep canyon in which the Rice Brook discharges itself into the Bush River."
Later in his book, Thorington describes his visit to the pass by writing, "A few days later we rode to Thompson Pass. It had cleared off, and we followed the trial up Castleguard River -the name given to the stream above the Alexandra angle -and through dense forest to the broad grassy levels leading to the summit lakes. Watchman Peak is charmingly reflected in the lower lake, while from the pass summit, below Spring Rice, we could look far into the gloomy depths of Bush Valley with the unbroken wall of Mount Bryce descending into it. This western country is wild in its appearance and looks nearly impossible for horses."
