The descent from Allan to Allan - Collembola col went on pretty quick. It wasn't scree run but still loose which helped a lot on the knees. Then solid ground quickly led me up to the false summit of Collembola, where I faced a series of moderate down-climbs. I was too lazy to skirt around for most of them. I descent slightly towards skier's right for the last one in order to find a weakness. The rock was wet so I couldn't trust the friction, and that's why I didn't downclimb that band directly. Dark clouds were building above me and I knew thunderstorm was gonna come. I descent about 20m on the talus slope towards SE for a bit of security. The clouds passed by after about 10min and I used the talus slope for the rest of the ascent. Thankfully the last section only lasted about 15min long. I quickly took a panorama and signed the register. The last entry was Jeff Shaw's, in December, 2011. The pencil was in bad shape.
I didn't like bushwhacking solo so if not because of the thunderstorm I would side-slope around Mount Allan to get to Olympic Summit and descent Centennial Ridge Trail to get back. However, this time I didn't have a choice, instead I quickly made my way down the SE ridge (So Nakagawa's descent route). It took me no time to get down this slope. Just about getting to the drainage, severe thunderstorm hit from behind, lightnings, thunders, and downpour. From the drainage you have to bushwhack about 1km to get to Marmot Basin Road. The bush was quite thick, and since rain was falling I got soaked very soon. The next half an hour was the most miserable of the day. I got lost in the forest and din't know exactly where was the road nor ski runs. I just picked a straight line with massive amount of bushwhacking and dead fall negotiating, and got completely soaked everythere. While listening to thunders above, I had to shout loudly for scary away the bears. I had no reference except for my watch. I knew I shouldn't spend too much time for just 1km distance. I eventually reached a ski run, and followed it down. I still had to make calls as bears love these open slopes, the good thing was I could see them and they could see me as well. The slope went on forever and finally I reached the Skogan Pass Trail, which joined Marmot Basin Road soon. Another 1km or so, I was at Nakiska Ski Resort. Note it was down-pouring all the way from the start of bushwhacking to Nakiska Resort... That was awful, but since I had extra clothing in car it shouldn't be a problem. Because I was moving I could keep myself warm. I didn't bother to use the Hidden Trail, instead I picked a longer way along the road to get to Ribbon Creek parking lot (avoid bear problem for as much as I could). I got no extra boots except for the mountaineering boots so this would be my last day of the trip. Weather also looked hopeless on Tuesday, with 20-30mm rain, so I drove back soon.
