Out of place contrail

I was bringing my dog back from the park.

when I pulled into my parking space I noticed an unusual contrail type thing in the skies out toward the east in the area of Denver International Airport.

I am older and I don't see real well and could not make out a craft making this contrail.

I am not sure how long it lasted I was called away to the phone.
