9-Foot diameter igloo on Hollyburn Mountain

As the twenties decade approached, one of our old group championed the idea of making another igloo. The plan became to head into the forest about 9:30 AM on January 5, 2020, to build a 9-foot inside diameter igloo. We’ve done this before, but the weather, the quality of the snow, and the people assembled make each igloo unique. Because it involves several hours of teamwork, these events are somehow memorable.

It had been a wet week at sea level, but above 3000 feet in Cypress Bowl Provincial Park, above West Vancouver, BC, Canada, there was lots of new damp snow. This made for easy construction using the tool called The Icebox — a system that uses a plastic slipform for building the blocks of snow on the wall of the igloo.

We have been making igloos this way since our first one on January 23, 2000. More details about the new one are at the hikers’ forum, ClubTread. That post is part of a thread about several igloos we’ve made going back to the year 2006. The thread also includes some time-lapse movies of the construction process and a map of the location. Except for one day of rain, the temperatures up there have remained cold, and a huge amount of snow has fallen during the past two weeks. I would love a report on current condition of the igloo. If you plan to go, read that Clubtread post, and take a shovel.

New Years Day Igloo — 2018 on Hollyburn Mountain

A decade ago my teenage daughters and our friends loved building igloos. I was surprised when I was requested to facilitate an igloo on New Year’s Day. Eight of us worked all day to build a 9-foot inside diameter igloo on Hollyburn Mountain, at 3020 feet, just up the hill from West Vancouver. Dave took a time lapse of the construction.


In the week that has followed, the weather warmed and there was lots of precipitation. Because of a local inversion, the temperatures at the altitude of the igloo meant that it rained… and then snowed. Today, January 9, I was in town, drove to the trailhead, and walked into the site of the igloo. Here is what I found.


The igloo was a blocky mound in the snow. The catenary profile was gone.

When I arrived, all I could see of the igloo was a blocky mound in the snow. The catenary profile was gone. Had the igloo collapsed?

The top of the igloo looked very low. The door looked okay.

The door and tunnel was in good shape, and the ‘foundation’ had not sagged. But the top of the igloo looked very low

I cleaned up the doorway in preparation for entering. Note the size of the shovel compared to the height of the igloo.

When I tried to sit on the floor of the igloo, with my legs in the entryway, I would bump my head on the roof. When the igloo was built, the top of the roof was 170 cm above the floor. Here, I cannot stand my shovel, and it is about 40 cm long. The igloo is slowly collapsing — like a balloon deflating.

There is a post about the plan for this igloo, and reports of our earlier igloos on the local hiking forum: Clubtread. Scroll the three pages of that thread for more details. The tool we use to make the igloo is Grandshelter’s Icebox®. We’ve made many igloos since we acquired it in the year 2000.

At this low altitude site, which is only a few hundred feet above the snow line, we don’t expect the igloos to last long. In a shady spot above 5000 feet, we might expect these structures to last for weeks or months.
