Bighorners of the Eastern Virgin

Bighorners of the Eastern Virgin is a side quest $$

Detailed walkthrough
Talking to Follows-Chalk about interesting wildlife in Zion will initiate this quest. Once it is received, head to Angel cave and go up the slope to the east of the camp. After maneuvering across the river over the three rock bridges, the Courier will find the lost mountain bighorner calf at the end of a narrow passage opposite the end of the last bridge.

In order to complete the optional part of the quest, the Courier must not get too close to any of the other bighorners, otherwise they will attack.

The Courier has to then to feed the lost calf a banana yucca fruit to get it to follow them. The Courier will need three or four banana yucca fruits (there are three banana yucca plants along the route) as the calf periodically stops, and has to be fed another before it will continue. It can take 5–10 seconds after feeding for the calf to resume again.

The Courier should then return across the rock bridges to the bighorner mother. They must then choose to either return the calf or keep it and if the former, speak to Follows-Chalk to complete the quest and receive the reward. If any bighorners were killed by the Courier in the process of completing the quest, Follows-Chalk will still give the reward. He indicates that he understands, but wishes they had not been killed. If no bighorners are killed, the player receives 25% more XP for the quest.

Bugs

 * Sometimes the calf will not follow the player even if they offer it banana yucca fruit.
