Como Bluff

Como Bluff is a six-mile ridge formation in Wyoming that contains exposed layers of Sundance and Morrison geological formations revealing extensive dinosaur fossils from the Late Jurassic period. The ridge has yielded remains from different dinosaur species across its varied rock strata.

Scientific exploration of this ridge began in the late 1800s when researchers discovered its rich fossil deposits. Over time, fourteen different quarries were opened across the site to extract remains of large prehistoric animals.

This location gained recognition from the National Register of Historic Places in 1973 for advancing paleontological science. The site continues to shape how researchers and the public understand ancient life on Earth.

This site sits between the towns of Rock River and Medicine Bow in a remote area where roads are the primary access route. Come prepared with water and supplies, as facilities are limited and weather can change quickly in this high-elevation terrain.

A striking structure nearby called Fossil Cabin was built in 1932 using more than 5700 dinosaur bones collected from this site. This unusual building stands as a testament to the intense interest early paleontologists had in these fossils.
