I expect the monolith to disappear and periodically reappear at different places, e.g., inside a shopping mall, in SF harbor wild seal rocks, on the White House lawn during Biden's inaugural,etc.
But seriously, they should examine the monolith's RF characteristics, monitor/test the field strength around the thing to determine its size and whether it is wired into something.
