We will discuss the uplift and creation of our modern Rockies, destructive volcanic eruptions, and Colorado as a tropical rainforest! The second part of the hike descends towards the river valley itself via the Inner Canyon Trail, where the rocks get more mysterious. At the culmination of the hike, we visit the ruins of Castlewood Dam. We learn the story of its construction, demise, and how water, rocks, and society all intertwine!

On this interpretive geology hike we will walk 2.5 miles through the volcanic rocks of Golden's North Table Mountain, accompanied by an experienced geologist who will teach you all about the rocks and the geologic history of the Rocky Mountains.  These rocks formed from lava flows that erupted out of a volcano over 60 million years ago! You will learn to identify rocks and minerals and see details in the rocks that would never be obvious to the untrained eye.
