Like I wrote in my first post, that ditch is definitely man-made and it's definitely been there a long time...at least since 1930 & probably much earlier than that. I suspect it was a pioneer ditch/canal dating from around the same time as the DD and others. If you follow it in the 1930 aerial, it appears that this ditch took a more southerly route than the DD and crossed the area of the current day Maricopa Fwy only about 250 feet east of where the DD did. That is the remnant you found in the pic. It may or may not have been the "gully" that Omar Turney showed on his 1929 map. I'd really like to know the name of this ditch (if it had one), and what it origins were.roc2rol wrote:just a quick question
What do you think my picture is of?
It certainly look man made
Its not part of the gully that’s been mentioned
The research continues...
