UFO Map: Western USAThis map of the Western United States shows UFO sightings for all dates.
Sightings frequencies reflect population densities everywhere. In the West especially, sightings counts are uneven, often disproportionately high or low.
South-eastern Oregon and Montana, West-central Nebraska show very few sightings, while other low population regions like SE Washington state were quite busy.
Sightings tend to cluster along western highways, railways and rivers where towns and travelers provide witnesses.
Apparent alignments in remote areas may invite speculation.
