The Beaver Marsh Rest Stop Horde is a 130-Swarmer Horde Killer target at a rest stop on Highway 97. It is one of the larger southern Hordes and pays 4,000 XP plus Diamond Lake Trust.
Fill your saddlebags, carry every explosive slot and find explosive barrels and fuel tanks before you start. Lead the Horde through them, mine your retreat with proximity bombs and park the bike far down the escape route.
Hordes rest in their hibernation spot during the day and go out to feed and drink after dark. Hitting a sleeping Horde lets you set up traps first. Every Swarmer drops an ear, so loot the field afterward for the bounty collector.
