GNIS contains over 1,400 features named 'Cottonwood' across the American West. Why is everything called Cottonwood? In arid desert hydrology, the presence of Populus fremontii (Fremont Cottonwood) was the primary indicator of near-surface riparian groundwater for desert travelers, making it the most frequently applied empirical landscape name in Western cartography.
