Dexter

Dexter is a small city in Stoddard County, in Missouri's Bootheel region, sitting on Crowley's Ridge. General rockhounding references describe chert and fortification agate — blue, gray, pink, and white banded material — turning up in streambeds and gravel around the Dexter area. There's no official geological survey, county, or land-manager source confirming a specific pit, quarry, or public collecting site here, and the coordinates attached to this listing actually land well south of Dexter itself, in neighboring New Madrid County. Treat this as a loose regional lead rather than a mapped destination — worth a look if you're already passing through the Bootheel on Crowley's Ridge, not a trip to plan around.

Dexter sits in Stoddard County, MO, along US-60 and US-114. The coordinates provided with this listing (36.61429, -89.96237) reverse-geocode to New Madrid County — about 13 miles south of the actual town of Dexter — so there's no confirmed single pin to navigate to. If you're working this area, think in terms of Crowley's Ridge streambeds and gravel bars generally, not one fixed spot.

General surface collecting in streambeds and gravel bars, consistent with typical Bootheel/Crowley's Ridge alluvial geology. No source describes digging, screening, or hard-rock work here — this reads as a casual streambed-gravel pattern, if it's real at all.

Land status is unverified — confirm ownership and permission before collecting anywhere in this area. Bootheel streambeds run through a mix of public road right-of-way and private farmland; no Missouri Department of Natural Resources or county source confirms a public collecting site at or near these coordinates.
