Wow, jps1021, That's just great. I'll be trying them very soon. I use a Garmin, did not find the software with it, but I,ll download. And I've been thinking of trying Google Earth.

What is involved here is an old trail, unmaintained for about twenty years. I thru-hiked it about thirty years ago, and parts of it much more recently, but some parts were hard to follow even then. I have fairly good topo maps, but in some places, I have to try to find it with little to go on. I have been trying to pinpoint various spots using a grid on the map, but have not been able to get sufficient accuracy to identify the spots i'm looking for (sometimes have to get within several feet in order to find the traces of the trail where it is obscured in heavy bush). This should do it.

This process is not helped by the fact that I am in Canada and our topos are 1:54 instead of the US standard of 1:25. Hope the sites given cover southern Ontario.

Again, many thanks. jcp
