Rock House Cave, located in Petit Jean State Park near Morrilton, Arkansas, isn't a true cave but rather a large bluff shelter that has served as a significant site for Native Americans for approximately 8,000 years. The.25-mile Rock House Cave Trail leads to the shelter, showcasing unique geological formations known as 'turtle rocks'. These mounded, polygonal structures resemble turtle shells and were formed through spheroidal weathering of the Hartshorne Sandstone.The cave itself features over 100 rock art images created by Native Americans over 500 years ago, including a distinctive rendering of a paddlefish. The park is located atop Petit Jean Mountain, rising from the Arkansas River Valley and offering spectacular views. The moderate, short hike to the cave provides a unique opportunity to witness both natural geological wonders and significant cultural history.The sandstone and shale rocks in the park date back to the Carboniferous period, approximately 299 to 359.2 million years ago, when central Arkansas was submerged under a shallow continental sea.
