Sterling Hill Mine's "Big Diggg" on Saturday 4/29, Ogdensberg, NJ
RandyB posted a topic in Rocks & Minerals
Heading to The Big Diggg this weekend, anyone else going? For those who don't know the area there are 2 mines in/near Ogdensberg, NJ that are world renowned for minerals that fluoresce under UV light, particularly short wave UV light. Once a year they open not just the regular collecting area, but other sections of the mine grounds including night collecting. If you are a glowhound it's a great time to try and find specimens to add to your collection. This will be my 4th year and last year was my best for colleccting by far. Managed to team up with a couple of others which allowed us to combine our efforts and break some very large boulders down to manageable size targeting mineral types (and fluorescent colors) I hadn't found before. Here's some samples under regular light and short-wave UV:- 6 replies
