Preparing Yurt Site in Forest

[John G]

I'm looking for some advice folks ... I started clearing a forest location for my yurt last Fall however the snow came in late October and I didn't get it finished. The forest is very dense and tangled and all work is done by hand ... my chainsaw and shovel are my helpers. The 18 foot yurt is ready and waiting and the frost is out (3+ feet deep this year). Yurt is an outbuilding for various uses including in winter time and will have a wood stove.

Yesterday I removed 6 stumps that were in my way. The ground is somewhat level with a few inches of organic matter covering it plus a few stumps that are not in my way. I plan to use precast cement piers with adjustable steel supports to hold the main 3x6 rough sawn aspen (poplar) beams.

My question is "What kind of soil-moisture prep should I do to avoid excessive

moisture

under the yurt?"
I've considered scraping away organic matter, filling depressions, using aggregate or other screened material to help with frost heaving, laying vapor barrier (easily punctured when I have to walk on it during platform construction). Or just setting footings on a bit of crushed rock and see what happens.
I really appreciate any wisdom you folks would like to share ..
