Loot · Tundra · Dig
3 loot lines. The right column is the only one that matters: how many of the game's 21 areas carry the very same line. The longer the bar, the less the trip is worth it.

The area's 6 activities
The rest of the area's loot, one click away. It is the natural way around this level of the tree: you do not go back up, you move from one activity to the next.
