Outdoor adventures such as hiking, backpacking, and canoeing require topographic maps ("topos" or "topo maps"). It used to be that the only source was paper maps published by the United States Geological Survey (USGS), a government agency. Now, many different vendors republish USGS data. But how do you know which vendors' maps are any good? It is hard to get honest samples from vendors.
Hence, I publish visual reviews of topo maps, so you can decide what works for you.
If you have maps that I haven't reviewed, I would love to include them. E-mail me.
