Road To Sneffels
Heading up west of Ouray, Colorado is the road to Camp Bird Mine, the townsite of Sneffels (1875 – 10,600 ft – once home to 2,000 people), the Revenue Mill, the Virginius, Ruby Trust and other mines on the upper slopes of Mt Sneffels.
Unlike the road coming down from Engineer Pass, this road has a pretty much, mostly, usually not too bad surface. Just left of center, you can make out traffic on the Sneffels road.

Unlike the Engineer Pass road, the Sneffels road is even passable in winter

Sneffels: A town of 2000 people in the late 1880s, the Revenue Mill was the big employer, 600 men to process the vast quantities of silver ore coming from the mines around: “workers at the Revenue mill enjoyed favorable living conditions for the day. The three Revenue boarding houses had electric lights, indoor plumbing, steam heat, and the men were well-fed, reportedly off of china plates.“
But no one lives up there anymore …

Makes me think of “sniffles”. Weird name.
