If you show up at an unknown location, how do you find where you are on the map? Landmarks?

Resection. Find two or preferably three distinct terrain features (natural or man-made) that you can also identify on your map. Take a back azimuth from each feature, adjust for declination, and draw the lines from the features on your map along the back azimuth. Where the lines intersect is where you are.

If you're somewhere with no terrain features, you're screwed.

You can get free maps online if you search for them. Also Google maps will give you lat/longs. If you google "hawgview" and click the link that says Neo's CAS Simulator (you might get a warning message, but trust me, its safe) you can get MGRS overlays and anywhere you click on the map will give you the location in multiple formats and the elevation. It's basically Google earth with more features. You can put tactical map symbols on your overlay if that's your thing (smiley). I use it al the time for work.

I don't know what a back azimuth is without looking it up, but you explained it in a way that I was able to figure out how you would do what you explained. Thanks!

No problem. Back azimuth is just 180 degrees away from whatev your compass says.
