Geo 730: August 7, Day 584: Calcite Close Up

Several small veinlets of calcite show up here, one near the bottom with the lens cap (52 mm), another in the upper right middle, and a nubbin up near the top- that latter one may a continuation of the second. Another characteristic of this outcrop comes through well in this shot: the rock is totally rotten, essentially just a pile of clay with veins shot through it. I may have, on past field trips, referred to this sort of stuff as "metacrappite." Or not.
