This one is easy now. Just click the blue dot, and it will disappear from the map:
Click the map again and it will re-appear at the spot you clicked (or the address or place you searched for):
So why is the blue dot there to begin with? It lets you know the location that the light blue bar above the map is reporting the information for. In the above example, that’s Merrimack County, New Hampshire.
So if you want to get rid of the blue dot before, say, taking a screenshot, now you know how!
Sometimes you feel like a dot, sometimes you don’t.
Happy mapping!
