How was cavanal hill formed?

Cavanal Hill, located in Oklahoma, is often referred to as the tallest hill in the world, though it is technically a hill rather than a mountain. Its formation is primarily attributed to geological processes, including erosion and sedimentation, that shaped the region over millions of years. The hill is part of the Sans Bois Mountains and features a combination of sandstone and shale, resulting from ancient sea deposits and tectonic activity. Over time, natural forces sculpted the landscape, culminating in the prominent hill seen today.
