The Hotlum Bolum Route is a great route because there are very few people and the route has lots of different sections for variation. The climb begins in earnest at about 11K when you get on the edge of the Hotlum glacier. The crux of the climb is the traverse at 12K to the bottom of the "Ramp" which is a steep slope up to the "Step" at about 13K. This section can be very icy later in the season and has exposure to large crevasses.

This was a beautiful hike/climb done 8/15 -8-16
We left northgate trailhead at 2:20 pm and arrived at camp (9800 ft elevation) at 5:30. This part of the hike is a 4.5 mile walk from the trail head to where we camped. We enjoyed fresh ice cold water from the glacier that ran through camp , and a nice sunset before catching a few hrs sleep. We awoke at 2 am and began our accent up the mountain , we were able to stay on the moraine all the way up to the step where we needed to use crampons for a short distance up to the rabbit ears. From here we watched a beautiful sun rise over the Smokey valley below. We reached the summit at 7:20 am , had a bite to eat and headed back down at 8:15 to pack up camp to head for the truck . We reached camp at 11:30 , packed up and headed out. The trek back to the truck took 2 hrs. We had the entire mountain to ourselves for 2 days which I’m sure being later in the season and the assumption that air quality might not be good kept people away.

I would like to try this one again earlier in the season when the need to wear crampons on most of the climb is required. This was mostly a lot of climbing on loose rock , gravel and sand with the need for crampons and ice axe periodically once you get to the Step. I recommend this route to anyone looking for something more than the conga line that takes place up avalanche gulch during peak season.

Not for amateurs. Great climb, but definitely need crampons, ice axes, and short roping technique to mitigate slips and falls, especially above the crevasses. We camped at9600 ft and enjoyed the freezing glacial water before starting for the summit at midnight. It’s a long day, as we returned to camp at about 4 pm. We had the north side of the mountain entirely to ourselves for 4 days.
