You can buy at any GOOD map store a plastic conversion scale that will allow you to take the UTM values of your GPS (you have to switch your units on your system) and pin point exactly where you were at on the topo.
You overlay the scale on your topo map, draw a few intersecting lines an BINGO your there. It takes a little bit a figuring out but, you can input the UTM values into your GPS to put you exactly on that secluded bench. You can also take your way points and lay them out on your map. This tied in with the airial photographs you can down load on the internet gives you an amazing amount of information.
