Destiny 2's brand new Lumina quest has got a very wide variety of locations it can send you to, High Plains being just one of the many! Located on the Forsaken's Tangled Shore, the High Plains chest can be tricky to find.
To try and point you in the right direction, we've got a snazzy map featured below, as well as a number of tips that should help you find the High Plains Lumina chest in no time at all. Especially considering the fact that High Plains aren't that obvious of a region, either.
Lumina High Plains Treasure
As you may expect by now, High Plains is yet another location that the System Positioning Device can send you to, and its treasure chest is one of the trickiest to reach, when all is said and done.
High Plains are the initial location on which the Forsaken expansion plops you on, and the catch is that you may well have forgotten how to backtrack there after going through the main questline. Consult the map above, and keep in mind that you have to take the energy elevator in Thieves' Landing to reach Four-Horn Gulch. From that point on, take the small tunnel in the lower portion of the region to get back to High Plains.
When you get to High Plains, consult the map above and get to this location, where the Lumina-related chest will be located. It's going to be on a ledge below the main chunk of terrain, so be on the lookout.
We are cooking up a full Lumina quest, but in the meantime, we've got guides for other ornate chest locations. Shaft 13, Spine of Keres, and Sinking Docks are just some of the places where it appears, so stay tuned!
