"Cabin" plot on TOPO maps

[TintedSnow]

So I'm trying to find some exact cabin locations from some topo maps. Any ideas on how I could find the exact locations? How puts these markers on topo maps? USGS when they're doing surveys? I have some maps from 100 years ago that have the cabins marked. How accurate are they from back then? I'm sure the cabins were gone long before aerial imagery.

I’ve found old topo maps to be a great resource for finding old buildings. I look for where the building was in relationship to things that haven’t changed much over time, like roads, rivers and the contours of hills. Using those things as reference points on a modern map usually gets me pretty close. Good luck!
