Finding Fortbyte 49 is one of many Fortbyte locations to complete.
It is found in Trog's Ice Cave, a cryptic clue that helps to narrow down where to find it.
If you're looking for more to do in Fortnite, there are plenty of Fortbyte locations to discover.
Note this particular challenge is no longer able to be completed. That said, there are still plenty of other Fortnite Challenges as part of Fortnite Season 10, including Lost Spray Can locations, Fortnite Graffiti billboards, Gas Station locations and Fountain, Junkyard and a Vending Machine.
Where to find Fortbyte 49: Found in Trog's Ice Cave in Fortnite
Fortbyte 49 is located within Trog's Ice Cave. The obvious clue is it's within the frozen south-west corner of the map, and if you've been keeping up to date with Fortnite's challenges for a few seasons now, the location is a familiar one.
Specifically, it's just north of the larger island near the south coast:
There are two ways to enter. One is from above, where there's a hole in the ground surrounded by a set of trees. The easiest, however, is to the south, where the mouth of the cave is.
Inside is a wooden hut. Enter inside, and Fortbyte 49 is in the corner, ready for the taking.
What else do you need to know about the Trog's Ice Cave Fortbyte?
There are no other requirements to finding and collecting Fortbyte 49, so grab it and you're then done.
If you're struggling to get it - especially when the Fortbyte first goes live, since everyone else is doing the same - we recommend either coming back either on a later date, a later time in the match (you can hover over the location until the initial rush as gone) or by playing a less competitive mode, such as Team Rumble, where there are less enemies to kill you.
Fortnite Season 10 is here! These feature new Fortnite Challenges, including Consume Glitched Foraged Items, Lost Spray Can locations, Fortnite Graffiti billboards, Gas Station locations and Fountain, Junkyard and a Vending Machine.
There are also new Prestige Challenges, including visiting graffiti covered billboards and containers with painted window locations.
As well as the above, it's worth reading where secret Battle Star locations are found and the latest Fortnite patch notes.
