About this location

The Pompton River is a short, eight-mile stretch in Passaic County, New Jersey, formed by the confluence of the Ramapo and Pequannock Rivers and running south to join the Passaic at Two Bridges. General rockhounding roundups describe it as a gravel-bar spot for banded agate and quartz crystals after floods or low water — modest river collecting, not a named formation or mine. The DB listing for this location carries no specimen list of its own, so treat what follows as regional-guide inference, not a confirmed site record.

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

Quartz crystals and banded agate are the specimens most consistently mentioned for the Pompton River, found as loose gravel washed down from the Ramapo Mountains headwaters. Geodes are reported as a rare find in the same gravels. UNVERIFIED against a primary geological source — mindat lists a "Pompton River Park" feature, but without descriptive detail.

Collecting here

Gravel-bar and streambed picking after floods or during low water, when more riverbed is exposed. No digging is implied by any source.

Know before you go

Land status is UNVERIFIED along most of the river's length — some frontage runs through public parkland (Pompton River Park is a documented feature name), while other stretches border private property in Wayne, Pequannock, and Lincoln Park. The area is flood-prone — the river crested at a record 25.54 feet after Hurricane Irene in 2011 — so check current conditions and access before visiting.
