Hi folks, Nate & I were on an adventure last weekend, and on the ride back we were discussing nodules, so I took him to a site on the way back where i've encountered some interesting specimens. Can anyone identify? This one in the picture is pretty solidified, but ive discovered ones with space inside, and one with a very fine yellow powder inside which I unfortunately didn't bag & tag for analysis. But yeah, any ideas, not quite a geode...
