Below is a guide on the Sato’s Saga Crew Challenge in Borderlands 3 Bounty of Blood DLC!!
Vestige
Vestige #1
This Sato journal can be found in the southern part of town near the Blastplains map transition. To reach it, jump into the water then head under the bridge to find a hidden room.
Vestige #2
This journal can be found on a balcony. To reach it, head behind the building and use the wooden fence to reach the back of the roof. Head up the roof towards the front and use 2 wooden crates to reach the top of the General Store sign. Drop down onto the overhang then follow it left (right of the General Store) to find a gap exposing the balcony that you can jump down onto to reach the journal.
Vestige Cache
The cache can be found on the balcony of the saloon. To reach it, face the entrance of the saloon and take the path left up the stairs then climb to the top of the crates. From the crates, jump up to a balcony and follow it until you reach a gap. Run and jump to reach the next section of the balcony. Follow it along to reach the cache.

Blastplains Cache
This cache can be found in Fort Kickwater. To reach it, you will need to climb up some wooden crates and a wall marked with yellow paint. Once at the top, turn left and head through the doorway. Take an immediate right and crawl underneath the partially opened gate on the door to find the cache.

Bloodsun Canyon #2
This journal is located south of the Presentation Room fast travel point. After coming down the elevator, jump over either side of the rail to find the journal underneath the walkway.
Bloodsun Canyon Cache
The cache can be found east of the Presentation Room fast travel station. Look for a door with a green button to the left that has an electrified puddle in front of it. Walk on the plank to use the button then jump through the doorway to reach the interior room. The cache is located behind the sealed door. You will need to use the crystal on the column to break the crystals on the second level that are blocking a small room. Climb up the stairs across from the small room to shoot the power box, which will cause the sealed door to open.
