I think caltopo may not be publicly accessible anymore - use it for SAR, but we have access for that. On my phone I use Backcountry Navigator Pro. Some others use avenza and, as mentioned above you can add PDF maps to that - I believe all of the USGS maps are now digitally tagged so they'll work. You can get them at https://topomaps.usgs.gov/drg/

Still has it available for public use. The PDFs now have a limited life unless you pay a fee. Seems fair, as this is the most powerful mapping software I have ever used. Where else can you layer USGS topos on top of google earth layers.

Thanks for the info on Caltopo.

Backcountry Navigator is actually doing a Kickstarter this week for a new version with desktop mapping as well. Obviously will cost but they also have overlays for a lot of off-road routes.
