Handy way to find those old cellar holes

I know most already know about lidar and how it sees through trees to the ground, but I just wanted to point out an example for anyone on the fence or not using the technology yet. If you'll look at the USGS map with 3DEP hill shade enabled, it will clearly show what's below the tree canopies and with surprising detail. After confirming the site, and through some digging, it dates to about the 1850's, which isn't the oldest in the area, but still a good spot to hunt.
If you want to check the site out for yourself, here is the link https://apps.nationalmap.gov/viewer/ Top right of the screen are the layers you need to go through, enable 3DEP Hillshade

Awesome. Thank You.
Gonna try it on the wife's 200 year old family farm.
Over 1100 acres.
Mostly dense woods today.
Supposed to have over a dozen homesteads and worker cabins.
So far I've only been able to locate two home sites.

Zooming in I'm not getting the clarity.
Not seeing existing farm house or building's even.
Set for the 3dep and tried structure.

The closer you zoom in the fuzzier it will get. Play around with the different 3dep versions to find the best for your area. The 3DEP Elevation- hillside stretched seems to have some good detail in it for me.

Also I don't believe most modern structures show up on it, as I've looked for my own house and it's nowhere to be found except you can see the flat pad it should be on
