Yourdon family photographs: family travels

Black and white photograph of an unidentified woman sitting on a log by a meadow, location unknown. Ed Yourdon's notes: "I really don't know anything about this photo -- no idea when it was taken, or where ... It's obviously at the edge of a meadow, somewhere in Colorado or Utah. I would guess that the woman is a friend (maybe a relative?) of my grandmother, who probably took this photo. But all of that is just speculation."
