This challenge is part of Fortnite Season 4 Week 3 Challenges and you'll have to visit Panther's Prowl. It's a huge dark statue echoing the superhero Black Panther. Appeared during the v14.00, the monument is located on the heights, west of Misty Meadows.
Map
The landmark is very easily spotted from your dive out of the battle bus. You'll just have to land on the statue or on the base for the challenge to be immediately completed. Rifts can be found everywhere around the monument. Don't hesitate to use them if you miss your landing: they'll propel you in the air to try a dive again.
We may never know, but it's possible that Epic Games decided to create this challenge to pay tribute to Chadwick Boseman, the superhero in the latest Marvel productions, who recently passed away from cancer.
