Tremolite: dangerous but interesting!

Tremolite forms needlelike crystals and can come in green and other colors. I have been finding colorless to white tremolite in Cockeysville, MD. So I spent a couple hours looking for that mineral and some other things over the weekend, and I found the larger specimen in this video. Was looking forward to cracking it open, but then I found out on Wikipedia that tremolite is a form of asbestos and its needlelike fibers can cause asbestosis!
For more tremolite specimens from the same site (including with calcite crystals!), see my other Youtube video at Tremolite with calcite crystals
