Treasure Maps in Red Dead 2 show a drawing of an area with steps to reach the treasure. You can find maps on your own or purchase them from treasure hunters around the world. The Jack Hall Gang, a band of outlaws from yesteryear, left their stash of gold somewhere in or around New Hanover. You can purchase the first map in this treasure hunt from Maximo, a treasure hunter you can meet after starting Chapter 2 near Flatneck Station. He will offer to sell you the map for $5 if you decline, or you can kill him and take it off of his body. If you fail to collect the map from Maximo, it can be purchased from a Fence later on.
Jack Hall Treasure Map 01
The first map to the Jack Hall Gang treasure can be purchased from Maximo, a treasure hunter found on the ridge overlooking the river north-west of Flatneck Station and north of Bard’s Crossing, for $10.00. The map depicts Caliban’s Seat, a unique rock formation to the south of Valentine. Scale the hill on the eastern side to reach the top. Follow a path through the rocks from the top. Move along the ledge, jumping across gaps and mantling over ledges, until you reach a large swath of white granite with a small hole in it. You’ll find the treasure – and another map – inside. advertisement
Jack Hall Treasure Map 02 
The second map to the Jack Hall gang treasure is found by finding the stash from the first Jack Hall map. The location depicted in the map is Cotorra Springs, just east of the dividing line between the E and W Grizzlies in Ambarino. This is also the location of a Legendary Wolf, so tread cautiously in this area. Head to the west end of the springs area, where you’ll find a small circle of unique rock formations. The treasure stash is inside the central stack of rocks.

Map number three leads you to the lake at O’Creagh’s Run, just north of Three Sisters in the Grizzlies East region of Ambarino. To get there, head directly north into the hills from Emerald Ranch. You’ll find the gang’s treasure – two gold bars – under a rock on the small rocky island in the middle of the lake. The High Stakes treasure can be started either during a random encounter out in the world, or later by purchasing a map from a fence if the player has missed the random encounter enough times.
High Stakes Treasure Map 1
To find the first of the High Stakes treasure maps, you’ll need to keep an eye out for an older treasure hunter. He won’t willingly give up his map, so you’ll need to either rob him at gunpoint, kill or hogtie and then loot him, or just run into him hard enough to make him drop the map. We’ve had the best luck spotting him at the top of a large rock to the north-east of Riggs Station, though he can also appear in various locations between Strawberry and Valentine. Once you’ve collected the map, you’ll find the first treasure stash at Cumberland Falls, west of Valentine. Approach the base of the falls from the west, then swim across to the rocks on the south side of the falls. You’ll find a fallen tree allows you to get up to the side of the waterfall – climb up behind the falls to collect the stash and the next map. advertisement
High Stakes Treasure Map 2
The second map will lead you north, into the Grizzlies West. This treasure stash is located above the frozen water of Barrow Lagoon, between Lake Isabelle and Widow Rock. Head down onto the frozen lake and look for a tree bridging the ice-coated island and the rocky banks of the lagoon. You’ll find the treasure and the next map stashed in the knot of the log bridge.
High Stakes Treasure Map 3
This final map will take you close to Fort Wallace. It’s on the large rock formation directly next to Ft Wallace to the north-east. Ride along the path leading east around the front of the fort, then veer off to ride up the hill on the backside of the large rock face. At the top you’ll find a path leading down between the two peaks of the rock. Follow it down to the cliffside below and turn left. Follow the ledge and then continue up the thin ramp that rises ahead of you, crouching to make your way around the corner. There’s a slight drop ahead of you – jump down, then turn around and drop to the next ledge down. Jump across to the next ledge and crouch under the low overhang – you’ll find three gold bars stashed in the rocks at the end of the overhang. The Poisonous Trail is a unique set of treasure maps in that you cannot buy the starter map anywhere, nor will anyone tell you about it. Instead, you will have to stumble upon it in the wilderness, and the following maps will take you all across the lands in Read Dead 2.
Poisonous Trail Map 1
To locate the first map, head up to the West Grizzles where Chapter 1 of the game took place, and head southeast from the town of Colter you were holed up in to the small Cairn Lake. Enter the Cairn Lake Lodge, and look under the bed for a lockbox you can loot – which will contain the Poisonous Trail Map 1. The Map features an iconic looking rock face that looks like a head, with a path leading to the right winding past trees to the treasure. You’ll find this geographical feature in the state of Lemoyne, North of Rhodes, and North of the Hill Haven Ranch along the road up in the Scarlett Meadows. Look for the Face Rock on the left side of the road as you go northwest of Hill Haven Ranch. Consult the map and go right from the rock face past a tree and down a slope. Here you will see a withered tree trunk, and a fallen log behind it. Search behind the withered tree trunk to find a hole at the base you can inspect to find the next map piece. advertisement
Poisonous Trail Map 2
Upon finding the treasure map at the Face Rock in Scarlett Meadows, you will have your next clue. The map will feature a snake-like formation, and a mound with rocks where the treasure is located. You can find this geoglyph in lower Roanoke Ridge in New Hanover, just to the west of the Van Horn Trading Post along the lower road going towards the Kamassa River. Halfway along the road to the river past the train tracks, head south up the hill to find an abandoned tower you can climb. At the top, look down on the hillside to spot the geoglyph of the snake, which Arthur will draw in his journal. At the top of the hill is the circular end of the snake with a rocky mound in the middle. Climb down into the mound and inspect the hole to get the next treasure map.
Poisonous Trail Map 3
The final map you find at the Snake Geoglyph points to the location of treasure in a hidden cave. The map depicts a waterfall with a passage behind it, and a secret tunnel off to the right leading to treasure. Move north of the Snake Geoglyph up to the Elysian Pool in New Hanover’s central Roanoke Ridge. At the north end of the pool where the river empties out you will find a large waterfall. Leave your horse behind and jump headfirst into the waterfall, only to find a secret passage into a large cave system on the other side. As you move deeper past the initial cave tunnel, ignore the rest of the cave on the map, and look down on the right in the first large corridor for a small slope down to a pit. At the bottom of the pit, check the wall on the right for a small hole to crawl through into a new area. The next part has a crossroads with two paths – and by consulting your map you’ll find that going right is the correct choice. You can also find an abandoned campsite here with a lockbox that holds some valuables. Moving past the campsite, you’ll come out onto a ledge. Look to the left with your lantern to find a pit below you, and a lower ledge on the left that you must run to (tap the run button to build speed) and then jump across to land safely. After landing on the lower ledge, look for a long slope on the other side to fall down to a dead end with some water, and a pile of rocks on the left. Climb up and inspect the large rock pile to find at last the treasure of The Poisonous Trail – 4 Gold Bars, which sell for $500 a piece at your local Fence!
