Fun, weird, helpful, or little known fact
Another fairly easy alpine draba, this one has smooth, green, relatively large leaves and relatively large yellow flowers. It likes to sequester itself among rocks and other plants (in this case, Alpine smelowskia) for maximum protection from the elements. This photo shows how much mustard flowers—four petals, always—even of different genera look alike.
