Placer Claims Count in the Detector Maps app, Arizona

Satellite imagery © Mapbox, © Maxar. Layer data from the sources named on each card.

About this layer

This layer compares areas using placer-related records. Placer gold is gold in loose deposits such as creek gravel. Check the legend and available feature details to see how the displayed value is defined, then compare it with samples and drainage; the value is not a measurement of gold remaining.

What it is for

Use the legend to compare areas, then check geology, known records and access before choosing where to investigate.

Limits

A higher-ranked area is a research lead, not a guaranteed find. A lower-ranked or blank area does not prove an absence of gold.
