Frost horn - how do i get red crate?

[Luckzor♞]

Im OCD with these types of games and have to search everything but i can not figure out a way to get this crate. I tried falling on top of it but i just die even though i have 90hp.
Any help would be awesome

It's wooden, so just blow it up with grenades.

There is a guide about those things, and as pointed in the first reply grenades should work.
