Editing Front Range (section)

===Castle Rock Conglomerate===
Suddenly, 37 million years ago, a great volcanic eruption took place in the [[Collegiate Range]] and covered the landscape in hot ash that instantly torched and consumed everything across the landscape. An entire lush environment was capped in a matter of minutes with 20 feet of extremely resistant rock, [[rhyolite]]. However, as seen before, life rebounds, and after a few million years mass floods cut through the rhyolite and eroded much of it as plants and animals began to recolonize the landscape. The mass flooding and erosion of the volcanic rock formed the [[Castle Rock (Colorado)|Castle Rock Conglomerate]] that can be found in the Front Range.<ref name="ancientdenvers" />
