Two day solo trip to climb Mt. Cline. Drove in from Brooks Alberta on the Sunday morning and got to the trailhead at ~2:00pm. Hiked to the bivy site arriving at ~6:30pm. Saw one small black bear cub but no mother on the ridge of gravel that leads up the traverse below the cliffs before the waterfall. He was very close but disappeared in seconds behind the gravel.
The climb and return to bivy took roughly 9 hours (~6:00am-3:00pm). A few snow fields on the north-west side of Mt. Owen were passed by climbing/traversing over them on annoying talus. They had a few feet of ice around their edges so crossing without crampons was not an option.
Both notches are bolted on both sides which makes rapping into them easy and secure. I rapped into the first notch, scrambled up the other side and pulled my 40m rope with me. Then I coiled my rope only to discover that the second notch is only about 15 meters away. I rapped into the second notch, scrambled up the other side and then secured my rope to the bolts on the other side, leaving it on rappel for the return. Climbing out of the second notch on the return is the hardest part of the notches but it can be climbed relatively easily on the left side of the wall (looking down the mountain) at a very exposed corner. A single 3' step must be taken across a void onto a full boot sized foot hold. The climbing is easy (5.4) but it is very exposed and good to be on rappel using the rope left there on the way up.
Return to the car was tiring but straightforward (~4:30pm-8:00pm)
