Metal Detecting Resources: Historic Maps
Historic maps and aerial photos are some of the best metal detecting resources for improving your hunting game. They help you identify where people used to gather, even if those places no longer exist today. Old homes, roads, rail lines, parks, and town centers often leave behind great finds.
Below are some of the best historic map websites and how detectorists can use them.
David Rumsey Map Collection
A popular collection of high-quality historic maps with modern map overlay tools.
Why it’s useful:You can line up old maps with today’s satellite imagery to see exactly where historic locations sit now.
Historic Aerials
A website that provides historic aerial photos and topographic maps from different years.
Why it’s useful:You can compare old aerial images with modern views to spot former buildings, roads, and land use that no longer exist today.
Library of Congress
The Library of Congress has a massive collection of historic maps, including town maps and Sanborn Fire Insurance maps.
Why it’s useful:Sanborn maps show exact building locations and property uses—great for pinpointing high-traffic areas.
U.S. Geological Survey (USGS)
USGS historic topographic maps show buildings, roads, railroads, and terrain from the late 1800s onward.
Why it’s useful:Compare old topo maps with modern maps to spot structures or roads that have disappeared.
