The photo in The Times was of course Trout Creek Pass. It was identified by Jim Thompson, Joe Cogan and by email from Matt Hutson.
Jim thought it was after one of the big floods which washed out the Denver South Park Railroad tracks and there were many of those floods. Joe knew it was before the highway was paved so it had to be before 1934.
This is the road bed which was called The Pikes Peak Ocean to Ocean Highway. It was started in 1912 in New York and eventually went to Los Angeles.
The PPOO came from Colorado Springs through Hartsel over Trout Creek, many times close to the creek bed, and into Buena Vista. It went north to Granite, had a bypass up to Twin Lakes and went on to Leadville. It went over Tennessee Pass to Minturn and on to Glenwood Springs.
The route was taken over by the Federal Highways in 1926 and was eventually changed to Highway 24. The PPOO came into town on CR 313. It came onto Main Street at the corner where Trader Tads was and went west down Main Street to the Highway Garage (Simple Eatery and Trailhead) then went North on Colorado Avenue. It went out a mile and over the railroad tracks going north on part of what is now Highway 24.
The bridge over the Arkansas at Johnson Village was built in the 1930s for the new highway which then came into Buena Vista at its present route.
