I had to make a trip up US 36 toward Lyons today - 50 bikers at least! That trip always turns out to be pleasurable because of the Pierre Shale and the whole shallow ocean bed aspect. The Front Range sloping off down toward prairie way out there somewhere. I tried to find a photo but all I came up with was this stunning picture of Mt Sanitas near the mouth of Boulder Canyon.
