very close to the end of mineralogy

Carnotite is an ore of uranium.  It is a distinct yellow or greenish color and is often found incorporated into petrified wood.  Tyuyamunite occurs with carnotite (sometimes) but contains potassium rather than calcium.  I do have a sample of tyuyamunite in my collection.  It is supposed to be from Montana.  Amblygonite is found with cassiterite and topaz in pegmatites and can be pink and glassy in luster.  Triphylite is also precipitated in granite pegmatites but is black in color and softer.

The highway department has taken down my road signs for my shop.  They want me to buy new ones for nearly one thousand dollars, which is not feasible in the winter.  First I have to get the big saw fixed so I can generate more inventory.
