These are pictures from a geode collecting trip that
my dad and I went on. The geodes we found in this stream bed all
were eroded out of southern Indiana limestones. Geodes form in
cavities that are filled with mineral-rich water, usually quartz.
When the water moves through, it leaves behind the disolved quartz
in the cavity. As the rest of the limestone desolves away, the
quartz geode remains. About every 1 in 3 in this area are hollow
and display a beautiful crystal pattern when broken open.
Geodes in the soil around the steam.
This is a large limestone block with geodes stuck in
the eroded groves.

Even large geodes can be found in this stream.
This is one of the geodes that I found at this site.
