What type of legal description is Morty using if he refers to an iron pin on a state route?

Morty is utilizing a metes and bounds description when he refers to an iron pin on a state route. Metes and bounds is a method of describing land that delineates the property boundaries using physical features of the geography, such as landmarks, measurements, and directions. This system often includes specific markers, like an iron pin, to define the boundaries of a parcel of land precisely.

The presence of an iron pin indicates a physical point that can be referenced in the description of the property's boundaries, a key characteristic of metes and bounds descriptions. They provide both the starting point and details about the direction and distance to other points, culminating in a closed circuit back to the starting point.

This method differs from other legal description types such as rectangular survey, which relies on a grid system and does not use natural landmarks or specific physical markers, lot and block, which identifies parcels within a platted subdivision, and subdivision description which incorporates a reference to various lots within a designated subdivision area without relying on specific physical measurements or markers.
