Adularia, a potassium-rich feldspar that forms from hot fluids circulating in the rock.  Professor Ted Walker of CU, Boulder, took this scanning electron microscope pic of adularia cementing the particles of Fountain Formation.  This adularia cement has made Eldorado Canyon State Park a super climbing area.  Elsewhere, for example, Garden of the Gods near Colorado Springs--away from the Colorado Mineral Belt--where this cement has not penetrated, Fountain rock cannot be climbed because it is poorly cemented and very crumbly.  At Shelf Road, CO, there is a faulted hill of Fountain that is very crumbly, another example of the absence of adularia cement.
