Chest Run?

I'm looking for chest run ,my currently level is 75,thanks for the answers.

 

YOU ARE NOT THE REAL JIMMY! In all seriousness, Ice canyon. Along the top there are like 5 Tier 3-4 and a tier 2.

 

Ok thanks,i'm checking now

 

-There's a secret place I know of with two T3s that I visit often...Whatever.
-Half-Moon Island also has two T3s.
-The 'fake' Thanos Vault has quite a few loot chests, including at least three T3-4s.
-I've heard there are a lot in the Molten Heights, though that place is high-leveled and there are only found 4 high-tiered ones that I've come across.

 

I found only one tier 2 chest.
Where is the tier 4 or other tier3?

 

I can get on in a bit to show you kinda sick rn so :/ maybe another hour or two
