Sierra Nevada
The SierraNevada is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra runs 400 mi (640 km) north-south, and its width ranges from 50 mi (80 km) to 80 mi (130 km) across east–west.[Wikipedia]
Relationships      
InstancesentityThe universal class of individuals. This is the root node of the ontology.
 geographic areaA geographic location, generally having definite boundaries. Note that this differs from its immediate superclass Region in that a GeographicArea is a three-dimensional Region of the earth. Accordingly, all astronomical objects other than earth and all one-dimensional and two-dimensional Regions are not classed under GeographicArea.
 land formA LandForm is the class of geographically and/or geologically distinct areas that occur on Earth's surface, including mountains, hills, plains, valleys, deltas, and features of submerged land areas such as the ocean floor.
 mountain rangeA MountainRange is a row or chain of connected mountains.
 objectCorresponds roughly to the class of ordinary objects. Examples include normal physical objects, geographical regions, and locations of Processes, the complement of Objects in the Physical class. In a 4D ontology, an Object is something whose spatiotemporal extent is thought of as dividing into spatial parts roughly parallel to the time-axis.
 physicalAn entity that has a location in space-time. Note that locations are themselves understood to have a location in space-time.
 regionA topographic location. Regions encompass surfaces of Objects, imaginary places, and GeographicAreas. Note that a Region is the only kind of Object which can be located at itself. Note too that Region is not a subclass of SelfConnectedObject, because some Regions, e.g. archipelagos, have parts which are not connected with one another.
 upland areaAn UplandArea is a LandArea elevated above the surrounding terrain.
