Entry point of the map with a fast travel station, vending machines for meds and ammo, Catch-A-Ride and some loot containers, one of which is a refrigerator. The loot containers do not refresh as you cross the barrier between Sandblast Scar and Konrad's Hold and vice versa. However, ammo will respawn on a timer. The interesting thing about Sandblast Scar is that it can be used to reach an Eridium-encased weapon chest at the tail end of Konrad's Hold, once you cross the transition barrier.
A big open industrial place with multiple abandoned factory buildings.
There is a red chest inside the northern factory building behind a large tank.
There is not much in the way of exploration in the Sandblast Scar--most of the roadside buildings are inaccessible on foot. Instead the area is suited for practicing driving skills and vehicular combat.
There are a few Dook Hut bandit chests located at several "rest stops" along the way.
This is the only open world zone that contains no challenges. All there is to discover are the 4 locations and single red chest near the end of the map.
