Hundreds of fluffy clusters of white ellingsenite crystals scattered at the bottom of an open cavity in the phonolithic rock are accompanied by many beautiful green tufts of crystalline tuperssuatsiaite needles, in one corner of the cavity you can see, nestled, a conspicuous soft, white, mass of crystalline makatite.
