The host rock on this specimen is nearly completely covered with sheets of yuksporite. This mineral has a rose-brown color, and a silky luster. In some areas it looks like a mica, while in others it looks more like a pinkish-brown eggshell. A loupe reveals that it is componsed of a myriad small clusters of fibrous crystals, yielding the silky luster. A ridge of the yuksporite is well exposed, revealing that it is translucent.
