Final answer:
An irregularly-shaped parcel of land is best described using the Metes and Bounds system, which utilizes local landmarks to define property lines.
Step-by-step explanation:
The most accurate description for an irregularly-shaped parcel of land is Metes and Bounds. This system was introduced by English settlers during the colonial period and involves describing land based on local landmarks like trees, boulders, or streams. The metes and bounds system is best suited for irregular land divisions, which can often result in parcels of land with highly random shapes and sizes, as opposed to a systematic grid-like pattern.
