Were you using only the phone and not a Fitbit tracker? If so it's only going off steps, not GPS. https://help.fitbit.com/articles/en_US/Help_article/1875#Monit

If the terrain forced you to take a lot of shorter steps then that explains it. In 6 hours of normal steps you'd expect to walk about 18 miles.

The Fitbit app lets you take a GPS track using the phone's GPS (as the Charge HR doesn't have a GPS chip). It's not step-based. Standing still for a break still makes my mileage go up, and I can see the blue dot on the map in the Fitbit app jitter around a little - a few feet here, a few feet there. Here's an example of the generated map: https://imgur.com/a/yoqei https://imgur.com/a/yoqei (That's a ~5 mile hike in actual mileage - and you can see the issue very clearly between "miles" 4 and 5 on the map, where we likely took a long break, and in the longer distance between the downhill miles as we were moving faster)
