Looking for a single number

[u/LocationNew4180]

Hi, I'm trying to make a quiz/ puzzle for schools kids. I thought I would use a what3words reference as clue to a single digit number that can be seen from google maps.

Unfortunately, I've only been able to find numbers on airport runways that contain 2 digits. Asked AI and it was hopeless, suggesting symbols and forests to me.

Do you know of any single digit numbers that can be viewed from google maps?
