Exploring pumpkin pastures,
Playing on Default VI I found a killzone - a section at the end of a branching off path that allowed me to climb it but immediately killed me.

No clear indication this would occur, emphasis this was not like the normal clearly defined killzones from falling off - mostly because I was climbing up not falling down. 
Stair-like formation suggests can climb
Death suggests not meant to go that way

After going back over the footage I can confirm this showed as the end of the path, intended to be a wall.
