Historical Range Map of Gray Wolf and Rocky Mountain Locust in North America #3042446 (License: Personal Use)

The image is a historical biogeographic map depicting the former ranges of two iconic North American species: the gray wolf, shown spanning the Rocky Mountains and Great Plains, and the Rocky Mountain locust, confined to the Great Plains region. Geographic features such as the Mississippi River, Gulf of Mexico, and state abbreviations (e.g., WY, CO, KS, OK, TX) provide spatial context, while color-coded zones distinguish the Rocky Mountains (brown), Great Plains (green), and river systems (blue). The locust’s range ends abruptly south of Nebraska, reflecting its documented historical habitat limits.
