Do you have any ground level photos to link to?
It's important to note that there is the hint of a path there in 2006, but that there definitely seems to have been a great deal of "enhancement" conducted since then. Defenders of the Kirlins suggest that this earlier path was for access to the parkland ("open space" as they say in Colorado) behind the Kirlin's property, and they show similar neighborhood paths as evidence of how common these are--that a path doesn't mean that it was "Edie" who created "Edie's Path."
Also note that this is not the only case of this in Colorado. Fortunately, the court ruled against the wannabe grabbers in another case in Boulder County. Here's the ruling where he has to pay $33,000+ in expert witness fees, too.
Of course, there will be those FReepers who won't be happy with that, since the grabbers were trying to open up nature land for recreation. We can hope that justice eventually prevails in this case.
