It probably falls under something akin to fair use. NatGeo is likely using a lot of USGS geo data, but doing additional work on top, adding in trails, making the map nice, etc.
I tried to make my own maps once for my GPS unit, it gave me a new level of respect for mapmakers. It's not terribly hard to take the raw LIDAR survey data and make crude maps, but making a nice polished zoomable map with trails, POI's, etc is laborious.

It's not terribly hard to take the raw LIDAR survey data and make crude maps, but making a nice polished zoomable map with trails, POI's, etc is laborious. It was even more laborious before computers were involved in cartography. My first employer was full of old timers who manually carved contour lines and maintained trig stations.
