Day #89 Deskcrop: Herkimer Dolostone & Quartz Encrusted Vug

Near Middleville, New York the Herkimer Dolostone has developed a vugs which are commonly filled by doubly terminated quartz crystals known as “Herkimer Diamonds“. The one trip I made to the quarries at Middleville in search of Herkimer diamonds turned out to be less than completely successful. I lost a sweatshirt that day and found precious few “diamonds”. Probably my best find that day was from a low roadcut outside the quarries where I was able to recover this deskcrop of Herkimer dolostone with a large vug lined with lots of small singly terminated quartz crystals.
