Mallory Cave Professional Reviews and Guides

"This is a short but sharp little climb that takes you to an unusual location among the Flatirons. Start at the National Center for Atmospheric Research (NCAR) campus and end at the bats’ own Mallory Cave, about 700 feet above.

This is a fun, quick, but vertical hike that puts you right in there amongst the Flatirons. The start/finish and the destination are both a kick in the pants. The hike starts at the National Center for Atmospheric Research, on a pretty mesa top above South Boulder. Nature is the real architect here in South Boulder. The Flatirons, massive chunks of Fountain sandstone that have been torn out of the earth by the uplift of the Rocky Mountains, dominate the scenery. The 300-million-year-old layer of red rock was formed by the complete erosion of a previous mountain range, the so-called Ancestral Rockies."
