Hole'n'The Rock, somewhere in Utah. Guy blasted a cave, moved in. Serious underground. Now it's a tourist attraction with a grinning stuffed donkey. (Anybody seen that website with the virtual tour of the abandoned missile silo? Is there a website of the house that some people made in one?)

An earth-bermed soddie in South Dakota on the edge of the Badlands. It has wood siding. Er, facing. Cladding. Whatever.

This is an earthship that was a stop on the International Straw Caravan, but since it's not a "real" strawbale house and everything else in that section is, I put it here. Hope that's not a problem.
