The USGS topographic maps the tried and true backpacking map. They have the most detail for off the grid locations. They include rivers, lakes, trails, timberlines, and many more backcountry features. Most of these maps were made between 1940 and 1960, so they are not the best for urban areas where there has been new developments over the last 50 years. Topo Maps+ has two different USGS maps sources and you can view the maps either with or without shading. You can use the USGS topo maps from either CalTopo or Glacier Peak Studios. In general the maps from CalTopo have higher resolution.
