Hoppe Geode Farm

This fine locality was opened up for Geode Fest and I first visited it it 2009. This is a large acreage with Chaney Creek running through it. Geodes fill the creek bed although most of these are solid. The banks of the creek are full of geodes also and you have a better chance of finding a hollow geode digging them out from the banks. All of the geodes in the creek and in its banks are float, having eroded from the strata twenty or so feet higher up from the bed of the creek.

Last year (2012) the owners of this property were building a pond in one of the small tributaries feeding into this creek when they hit a pocket of geodes. This made this locality really fun as geodes can now be dug straight out of their host rock where the quality of the geodes is much better. The shale that the geodes are in is really soft and the digging is easy. During the 2012 Geode Festival dig the owner brought the bulldozer down to the pond bank quite often to scrape away the overburden making it almost too easy (if that's possible) to dig geodes.

Several of the small tributaries to Chaney Creek have the Warsaw formation exposed with geodes poking out, so it is fun just to explore the small hills and hollows of this property. The hollow just to the east of the house has an exposure of small geodes with calcite secondaries that are nice. I told the landowner about this exposure and he seemed interested in getting a machine over there sometime in the future.

The geodes come in all sizes... from tennisball to basketball size. Although there are not a lot of secondaries in the geodes, the quartz is nice with lots of iron mineralization making the crystals colorful. Some of the geodes have a bright red hematite dust coating the crystals, but I have yet to see a red quartz geode cracked from here. I am sure that time will come though as all the conditions are right at this exposure for one to appear.

Hematite on white chalcedony coated quartz crystals. Most of the time the hematite dust can be washed off of the quartz crystals. On this specimen the hematite has been absorbed into the porous chalcedony and will not wash out.

Aragonite and pyrite on yellow and clear quartz. This is a nice eight inch quartz geode half from the Hoppe geode farm.
