Some natural stone, some not

Well, it looks like the big stones are there naturally... tireless and extremely patient students hauled sand out of the bottoms of a few other units and cleaned off the profile of the unit with those cool stones, and it looks like 1) there are stones down deep in other parts of the site, and 2) there are clear natural strata above the stones, which means that they ended up there before people ever moved in to the area.

On the other hand, we've got a ton of fire-cracked rock (FCR), dark fireplace soil, and quartz flakes from tool-making coming out of another unit, so at least we know that people were actually there during a stone-tool-using time in Finland's past!
