About this location
Southeastern Iowa's geode belt is real and well documented, and the Skunk River runs right through part of it. The best-known stretch is between Rome and Lowell in Henry County, where geodes weather out of soft shale directly into the riverbed and its tributaries — the same belt that gives nearby Geode State Park its name. Further south, Keokuk in Lee County is the belt's type locality, where geodes erode from bluffs and creek banks along the Des Moines River system. The DB coordinate here sits along the Skunk River's lower reach, in the general geode-belt region, but isn't tied to one specific pinned bar or park. Treat this as a real regional destination worth knowing about, not a single mapped spot — the Rome-Lowell stretch or Geode State Park are the more specific starting points if you want a known location.
Always seek permission where required, follow local laws, and practice Leave No Trace. Locations and details are community-submitted and may be inaccurate. Not sure what's legal here? Read our full guide to rockhounding laws by land type.
Found Here
- Geodes — documented from the Skunk River's Rome-Lowell stretch in Henry County, and regionally from the broader geode belt around Keokuk. Look for round to sub-spherical masses with a rough, knobby, gray-brown chalcedony rind, ranging from golf-ball to basketball size.
- Petrified coral and limonite — plausible regionally given the area's Mississippian-age limestone bedrock (source of the geode belt itself), though not independently confirmed at this specific coordinate.
Difficulty
Getting there
The Skunk River flows through southeastern Iowa; the DB coordinate sits along its lower reach. The best-documented specific stretch for geode collecting is between Rome and Lowell in Henry County, with Geode State Park nearby as a mapped landmark. UNVERIFIED: no exact access point at the DB's own pinned coordinate was confirmed.
Collecting here
Best after spring floods recede, walking exposed creek channels and gravel bars at low water, scanning for the rounded, knobby geode shape among ordinary river rock. No digging equipment typically needed for float material; late summer/early fall conditions are generally favored once water levels drop.
Know before you go
Land status along this stretch is UNVERIFIED. Iowa generally allows collecting loose material from public streambeds, but private property lines apply to the banks — confirm access points before parking or walking onto adjacent land. Geode State Park, nearby in the same regional belt, is public land with its own posted rules and is a safer bet for confirmed public access than an unverified river coordinate.
