How do I unlock the Poisonous Trail treasure map?

The Poisonous Trail treasure map is one of the most rewarding collectibles in Red Dead Redemption 2, offering a multi-part treasure hunt that leads to valuable gold bars. To unlock this treasure map, you must first obtain the first map in the series, which is found during a random encounter with a treasure hunter. This encounter typically occurs in the wilderness, often near the Cumberland Forest or the area around O''Creagh''s Run. The treasure hunter will be sitting by a campfire, and when approached, he will offer to sell you the map for $10. If you decline, he may become hostile, so be prepared for a fight.\n\nOnce you have the first map, the Poisonous Trail treasure hunt begins. The map contains cryptic clues that lead you to three different locations. The first clue points to a tree near Window Rock, located in the Grizzlies East region. Look for a distinctive tree with a large rock formation nearby. The treasure is hidden in a crevice at the base of the tree. Use your Eagle Eye ability to highlight the glowing gold particles, which indicate the presence of the treasure. Collect the second map from this location to continue the hunt.\n\nThe second clue leads you to a cave near Cattail Pond, northwest of Valentine. This cave is partially hidden by vegetation, so use your map to locate the exact spot. Inside the cave, you''ll find the third map tucked into a crevice in the wall. Be cautious of wildlife, as cougars and wolves are common in this area. If you encounter a predator, use Dead Eye to quickly dispatch it and avoid losing health.\n\nThe final clue takes you to a waterfall in the northern part of the map, near the Wapiti Indian Reservation. The treasure is hidden behind the waterfall, so you''ll need to swim or wade through the water to reach it. Once inside, search the rocky area behind the falls to find the gold bars. Each gold bar is worth $500, making this treasure hunt one of the most lucrative in the game.\n\nTo maximize your success, ensure you have a good horse with high stamina for traversing the rugged terrain. Additionally, stock up on health tonics and ammunition before starting the hunt, as you may encounter hostile NPCs or wildlife. Use your map and Eagle Eye frequently to stay on track and avoid missing key clues. Finally, save your game before each step of the hunt to avoid losing progress if something goes wrong.\n\nFor new players, it''s important to note that the treasure hunter encounter is random, so you may need to explore the wilderness extensively to trigger it. Experienced players can use fast travel to revisit key locations and speed up the process. Regardless of your skill level, the Poisonous Trail treasure hunt is a rewarding challenge that offers both excitement and valuable rewards.
