Lamb Spring is a unique resource for the Denver metropolitan region and is valuable for public education and research, because it is rich with information about natural and human history. The Lamb Spring Archaeological Preserve (LSAP) is an internationally significant archaeological site containing bone beds of extinct Ice Age animals and artifacts from later human occupation at the spring. Extinct Ice Age animals found at the site include over 30 Columbian Mammoths, the largest number known from any site in Colorado. It also contains the remains of Ice Age camels, horses, sloths, llamas, and wolves.
