I can mostly translate the message on the stick,
Each circular shape represents a camping site,
the section that resembles a road is usually a river or a seasonally flow creek, etc,
the markings with the depicted water-course are locations of permanent sources of water that only require the person to dig down in to the sandy creek bed perhaps a foot or so to find the water,
the dots along the "creek bank" represent trees that can usually are homes to birds and bird nests, e,g. a chance of finding extra foods, and, each of the larger circular shapes along the sides of the "creek"{ represent good and ideal camping sites.
The spacings between each depicted "camping site" represents 1 day's journey by foot.
