Fort Wayne (Maumee River)

Fort Wayne sits at the headwaters of the Maumee River in Allen County, Indiana, and the river corridor here carries Pleistocene glacial float scattered across northeastern Indiana by the ice sheets — agate, jasper, and chert erratics mixed in with Devonian fossil coral and petrified wood transported down from the north. General rockhounding sources point specifically to Maumee River gravels at Fort Wayne, plus recently tilled farm fields nearby, as the best places in northern Indiana to find agate and jasper. This is glacial-till collecting, not a mine or quarry — small, waterworn pieces scattered through gravel rather than concentrated deposits, and best treated as a patient gravel-bar search rather than a guaranteed haul.

The Maumee River forms at the confluence of the St. Joseph and St. Marys Rivers in downtown Fort Wayne and flows northeast toward the Ohio state line. Productive gravel is reported along the river's course through Allen County, with access via riverside parks and bridges. We found no single named park or pull-off confirmed as the best spot.

Surface and gravel-bar picking, hand tools only — a small shovel or rake to turn over gravel and a bucket for finds. Freshly tilled fields near the river corridor are also worth checking after plowing, per general regional guidance. Water levels are lowest and gravel most exposed in late summer and fall.

Land status varies along the river's course — some stretches run through public parks with open riverbank access, others through private property. Confirm you're on public land or have permission before collecting at any specific spot, and check with the City of Fort Wayne Parks & Recreation Department for rules at any specific park you plan to use.
