Looking to Alaska

What options do I have besides wood for natural building in south central Alaska? Is stone abundant? Provided I bring in straw, does the soil lend itself at all to cob? I'm just sounding out options here. I presently live in the lowest part of Arizona and am sick to death of the sun, heat, salty earth and salty water. One thing we do have here is many rocks/boulders of all shapes and sizes, as well as clay. Stonework and adobe are what I'm most experienced with.

Does it ever stop raining long enough for the cob to set up? Hahahaha, best of luck! Alaska is where it's at.

Obviously I have no idea about your actual question...

Alaska is mostly timbered. Creeks and rivers have stones. Depending on where in Alaska, they aren't many roads. most are logging roads. Cement, mortar, hardware, and other items are at least 2x more expensive depending on weight. Most items come to Alaska by barge. Ordering custom doors or windows could take a month longer than the lower 48.  Many people have sawmills and can cut your timber or sell you lumber. You'll need your own truck big enough to haul your lumber in most remote areas. Many make log houses. If you decide on a log house, study it first.
Not much sun in the winter and really low in the sky when there are no clouds. If there are clouds, dark days. Lots of sun in the summer. But the soil has to warm before planting. There are farms. If you have livestock you need to have a way to keep the bears from making a meal of them, your garbage and you. There are wolves. Coyotes on steroids.
