Anyplace-America contacted me about adding a link to Trailism’s mapping resource page. After a little surfing on the Anyplace-America website I decided it might be worth creating a post to say it’s worth checking out. Their trail page is a good start. The PDF topo maps seem to be geo-referenced, but I have not confirmed this. Many of their maps are USGS TOPO maps that are freely available on the Avenza PDF map app. Hopefully in time they will populate their site with more maps, but for now they have some (free) maps of interest.
My guess is that Open Street Maps or Google will render many of these other trail resources obsolete in the near future. Of course having a PDF map is better being that no cellular service is necessary.
