I'd like to show someone a specific point on Google Maps. How can I put down a pin (and remove all other pins) and get a URL of the resulting map?
How to communicate a position as a Google Maps URL?

You can also share the map by centering your view on the location you right-click.  Once this is done, you can then link to the maps by clicking the link icon (looks like a chain segment) in the upper right corner.  This will re-create your viewed location anytime you go to the URL it gives you.
