From Angela, a reader in Alaska: “I just wanted to add some updated info. I have been searching high and low for scoria. Alaska doesn’t have readily available sources. I have contacted a long list of people and while we can find the volcanoes and a scoria pit even, there’s no way to get it to the general public. Which really frustrates me because I’m been hot on the trail for a long time trying to build an earthbag home for us. If anybody gets any bit of updated info, please share.”
Owen: Your best bet then is to build a straw bale house. Bales are super insulating, easy to work with and should be available in many places. Search this blog for lots of information on strawbale building. One interesting design is called a straw bale yurt. The cold and wind would just blow around a small home like that and be real toasty inside. Thanks for searching for scoria and reporting back. This will save others from going through the same process. If by chance somebody should find some lava rock/scoria in Alaska then please leave a comment here.
