Hollow log

Hollow logs are white logs that have been hollowed out and have items stored in them. The items are usually various meat or food items, antivenom, or some other type of medicine. They are found in the Zion Canyon. Follows-Chalk first mentions the log to you while travelling to see Joshua Graham.
