observatory hill in marquette cty is a large outcropping of rhyolite almost two billion years old. tallest point in the cty, oak and hickory forest on the slope, a spectacular glade community toward the top open to the sun.

we spent a good amount of time soaking it up in the glade, laying on the rhyolite. first id of motherwort and tall wood sorrel!
