Rode Dickerson Mine in the early afternoon today. There's a thin, crusty ice base with a dusting of snow on the trails at the moment. It might be be safe with unstudded tires as the underlying ice has a some texture to it, along with the thin coating of snow -- hard to say. I had the good fortune of guessing the conditions right and had mounted up a studded Dillinger4 (front) and studded Dillinger5 (rear), which performed great. Sadly, when the layer of ice melts with warmer temps, it will probably leave the trails very soft and vulnerable. Get there and ride Dickerson before that happens if you can!
