Rocky Mountain high stress

A switchback turn on the west side of Wolf Creek Pass about 18 miles east of Pagosa Springs on U.S Highway 160 is one of the more dangerous areas on the mountain pass with a 200-foot dropoff on the other side of the curve.
How it was done

To determine the worst mountain pass in Colorado, the Journal assembled several bits of data into a spreadsheet.
The Colorado Department of Transportation provided a list of 30 passes.
Only year-round passes were counted. (Sorry, Aspenites, Independence Pass doesn’t make the cut.) Raton Pass was not included because half of it is in New Mexico.
CDOT spokeswomen Stacey Stegman, Nancy Shanks and Mindy Crane also tracked down data on elevation, steepness, traffic, accidents from 2009 to 2011, chain law days in 2011 and closures in 2011.
We counted switchbacks using Google maps and calculated the distance to the nearest town using CDOT data and Google maps.
Real-time snow data is hard to find, so we used the average April snowpack over the last four years from the nearest U.S. Department of Agriculture Snotel station. Sometimes, Snotels are right on the pass, but others are several miles off the road.
Chain law and closure data was incomplete, so we gave each category half the importance as the other variables.
A little bit of computer-assisted addition later, and presto: We can call Wolf Creek Pass the most white-knuckle-inducing drive in Colorado.
