Just keep following this until you make it to a natural rock bridge. You can climb up this slope to enter the mountains. Go to the Dead Horses Camp and look for a slope just past the tents. In order to help, you’ll need to walk up into their hunting grounds. You can just fast travel back and find him at the camp afterward. Don’t worry, especially if you still have Follows-Chalk. If they’re set to fire at will, then you’ll probably lose the optional objective. Bighorners killed by your companion will count toward your count, even if you never fire a shot. If you choose to do this, you will probably want to ditch Follows-Chalk at camp, since he has a chance of messing things up for you. You’ll get more of a reward if you can do it, and it’s not too hard. Ideally, he wants you to avoid killing any of the bighorners, since that will just make things harder on them. You can get these banana yuccas by looking for the tall stalks along the sides of the roads throughout Zion. You’ll need to have three banana yuccas for this, but you can probably grab a few along the way. He figures that a calf has gone missing, and believes that you can take care of things. This is bad for everyone, since the tribes will either face a food shortage or have to kill the angry bighorners and destroy the local herd. If you talk to Follows-Chalk about the local wildlife, he should mention that the local bighorner herds are all riled up. This is a fairly quick quest if you know what to do.
