What is an Aliquot Part?
An aliquot part is a unit of measurement defined as part of the Public Land Survey System (PLSS). A Aliquot Part describes a subsection of a larger land plot. These come in groups of four, defined by the cardinal directions so that one plot can be divided into the north-west, north-east, south-west, and south-east aliquots.
These are also recursive so that a small plot of land could be defined as being in the NE SE, or the north-east corner of the south-east corner of some larger section. It is important to note that there is some variation in BLM documentation of aliquots where some claims have a list such as 'NESE', defining a part within a part, while, for other claim types, this may define two, distinct parts that, together, define the entire claim.
