GMS Field Trip
Impact Crater and an Old Iron Furnace in Tennessee
Saturday, March 9, 2013

On the fieldtrip to the impact crater for shatter cones and to the old iron furnace for slag, we had about 44 rockhounds from GMS, Cobb, Memphis (MAGS), Knoxville and Middle TN. After a little bit of trouble getting to the meeting place, we went straight to the shatter cone location and everybody had a great time. A lot of very nice (360 degree) shatter cones were found and nobody left without something.

Then we went to the old iron furnace and found slag in almost all of the colors of the rainbow -- blue, green, purple, and black with swirls and strips. Also, some fossils (coral and crinoid) were found and some interesting sand. Everyone got plenty very quickly as this is a very easy collection site. Special thanks go to our friend Marvin for setting up the shatter cone trip and teaching us about the impact crater and also John Martin of the Middle Tennessee club for the furnace trip.

Everyone had such a good time there are already plans for a bigger and better trip next year, so if you missed this year make sure you go next year!

though there was no doubt it was coming with us one way or another
