Here is a HUGE geode that I found in the headwaters of the Green River in KY. The areas from Garrard/Lincoln counties down south is full of geodes. There are nearly as many geodes as the bedrock as there is sandstone/limestone rocks. The upper Green, Buck Creek, and Dix River are packed full of Geodes. I have found 3-4 different mineral types there, but most are some type of Quartz. I have several geodes in my tank and some outside in a bucket waiting to be used. This one is part of my landscaping. There are also beautiful agates found here in Central KY, but I have yet to find one and cut it open. I know these are not fish, but they are related. Maybe we need a native geology section, or that may be getting too far off the topic of native fish.


I thought these were interesting and look forward to getting back down there to do some more rock collecting.
