Toadstool Geologic Park, Protected geological site in northwestern Nebraska, United States.
The 300-acre park contains weathered rock formations shaped like mushrooms, created through millions of years of wind and water erosion processes.
The sedimentary layers within the park date back 30 million years to the Oligocene period, containing numerous fossils of ancient mammals.
Native American artifacts discovered in the area indicate prolonged human presence, with evidence of hunting and gathering activities from prehistoric times.
The park features primitive camping facilities, hiking trails, interpretive signs, and requires a small entrance fee for day use and overnight stays.
The rock formations consist of sandstone caps balanced on clay pedestals, forming natural sculptures that resemble giant mushrooms across the landscape.

The selection presents geological formations from basalt columns in Northern Ireland to salt flats in Bolivia. It includes glaciers, volcanoes, canyons, waterfalls, and coral reefs. These geological structures were shaped by natural forces such as erosion, tectonic movements, and volcanic activities over millions of years.
Rock pillars and spires shaped by erosion stand as natural monuments across various locations worldwide. These geological structures, known as hoodoos, display different colors and shapes based on their mineral composition and environmental conditions. From the red rocks of Utah to the limestone formations of Turkey, these sites present geological formations created over millions of years through wind and water erosion. These formations develop through differential erosion, where softer rock layers erode faster than harder layers, leaving slender columns often capped with protective harder rock. Visitors find such structures in desert landscapes, canyons, and plateaus where conditions favor their formation and preservation. The color palette ranges from white to orange, red, and gray, depending on the minerals present such as iron oxide, limestone, or clay.
