The map does the reading for you

GOLDONGO scores entire stream networks for the trap geometry this guide describes — slope breaks, inside bends, junctions and bedrock. Pick your region and see where it stands.

This guide is general education, not advice for a specific place. A score, a map or a sentence here is not a licence to dig: the rules for prospecting, land access and protected areas differ from place to place — learn the ones that apply where you are before you go.
