Finding old development under modern forest

It's amazing how quickly a forest can grow back on clear-cut ground. I've written here before about a National Seashore in Wisconsin that looks like forest primeval today, but was, less than a century ago, a treeless expanse of small-scale timber, fishing, and stonecutting industry. The same sort of thing happens in New England, where colonial and 19th-century farms, roads, and fences have been allowed to disappear beneath a forested landscape — and to disappear well enough that people often forget they existed, at all. Now, digital archaeology is helping to uncover these sites once again.
