    Do they only shown 50’ changes in elevation? The reason I ask is, where I live in Midland county, it seems none of the topography maps I have come across are accurate, or they don’t show reality. I took a hike the other day and it showed on my elevation tracker app that I varied in terrain, anywhere from 645’ to 686’, yet none of these changes show on maps? I see all sorts of small ridges/valleys, but they aren’t mapped. Is this normal?

    Midland County's GIS website has a terrain layer you can turn on. It will show 1' contour intervals. It's slow on a phone but a PC or laptop will work fine.

    Ok I just read about using a paper topo. map and compass to navigate in woods and water.magazine and it has my interest.
    But it did not say where to get there maps.
    How do I get these?

    I see plenty of contours on onx maps and it's not that hill around here.

    You might be able to get a paper topo online. If you are shooting azimuths you will need a protractor, a declination adjustment for your area, a marker, and preferably a compass with a sighting system. But you are much better off with a cell phone and just a basic compass and direction to nearest road as a backup.
