概要
Hours on a Sandstone Ledge: How She Measured Time

The thought of being stranded where water can rise four feet in an hour is a quiet kind of terror - and Dawn West spent seventy-two hours measuring every passing moment by carving marks into sandstone with a Leatherman file. How did a methodical twenty-three-year-old, who planned every route and even carried a tiny green brachiosaurus, turn meticulous preparation into a minute-by-minute survival ledger?

In this episode, you will hear the timeline of what happened when Dawn entered Calloway Canyon and the canyon filled; we follow her route plan, the rising water, and the exact marks she left to record time as the exit remained submerged. What did her marks, times, and initials reveal about her understanding of how much longer she had?

Person: Dawn West
Date: October 1-4, 2019
Location: Calloway Canyon, Marble Fork trailhead northeast of Durango, Colorado
Duration: Seventy-two hours stranded

- Dawn filed a route plan with Entry: Tuesday, October 1 and Planned exit: Thursday, October 3.
- One point two five inches of rain fell across the Calloway drainage basin over eighteen hours.
- Flash floods raised water levels by four additional feet by Tuesday night, submerging the exit under six feet of moving water.
- Dawn stood on a ledge approximately fourteen feet long and four feet wide, eight feet above the canyon floor.
- She marked the sandstone with a Leatherman file every two hours, inscribing the time and her initials D.W.
