Up to date detailed US topo maps
What hiking topo maps should I buy in order to hike in US (e. g. Yosemite, Grand Canyon, Yellowstone and other national parks)?
Is National Geographics maps the only available up-to-date option? Do they offer full US coverage? USGS seems to be a bit outdated to me, right?
Are there any online/mobile apps options or do I need to buy just the printed one once in US?
