Hell's Half Acre Lava Field, Lava field in Bingham County, US.
This basaltic formation spans 150 square miles across the Snake River Plain, featuring numerous volcanic formations including tubes, cracks, and cinder deposits.
The site received its name from fur traders in the early 19th century, and Benjamin Bonneville documented the area during his 1833 expedition.
The National Park Service designated the northwestern portion as a National Natural Landmark in 1976, recognizing its geological importance.
Visitors can access the area through maintained trails managed by the Bureau of Land Management, with seasonal closures during winter months.
The lava field contains ten circular pits and two large lava tubes near its summit, alongside a depression from a previous lava lake.

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.
