Final answer:
An adequate metes and bounds description must include a starting point, boundaries description, and measurement of distances, but not necessarily a map or diagram.
Step-by-step explanation:
The question relates to the metes and bounds system for describing land parcels, which does not necessarily require a map or diagram for an adequate description. Metes and bounds is a system of land description that uses natural features and measurements to define the boundaries of a parcel of land. An adequate metes and bounds description must include a starting point, boundaries description, and measurement of distances. While including a map or diagram might be helpful, it is not a requirement for this type of land description.Given the context of the examples provided, such as the use of local landmarks like trees, boulders, or streams, it's clear that these are the elements that are necessary to create a legal metes and bounds land description. Since a map or diagram is not mentioned as a mandatory inclusion for the registration of land claims using metes and bounds, it can be considered an optional addition, though beneficial for clarity and verification.
