Natural monuments or landmarks represent the first level in the hierarchy of monumentation because they are the most stable and enduring reference points found in nature. These include features such as trees, rocks, rivers, and other physical features that have existed for long periods of time. They provide a reliable basis for determining boundaries and are often used as starting points in the surveying process.

The reason for placing natural monuments at the top of the hierarchy is that they have a historical significance and are less likely to be disturbed by human activity in contrast to artificial monuments, which can be moved or destroyed. Natural landmarks help to establish a clear understanding of boundary lines and property demarcation, making them vital for effective land surveying.

Meanwhile, other options like artificial monuments, adjacent boundaries, and designations of quantity all have their roles but are secondary to natural monuments in terms of stability and reliability when defining boundaries.
