I watched the first three episodes and just couldn't take any more. In my opinion the writing is bad and the acting, particularly by Ellie Bamber, is awful.

I went back and looked at some pics from that trip. Right around Scagway and the white pass trail it was all conifers. But we went a bit north into the Yukon Territory and there was a good amount of yellow up there in September.

I was up there in late September. Temps were usually in the 40s and the mountains were snow capped

I got up to Skagway and into the Yukon Territory in 2013. Beautiful. Best trip of my life.
