Convert List To Table And Stay Updated Dynamically?

I have a list or log that is updated by a number of people on a sharepoint file. The list consists essentially of 2 columns - lets call them Location and Date.

The Locations are populated from a pulldown list but can be repeated a number of times throughout the list. I have the list set up using Table Formatting so the range updates dynamically

Example:
Location Date
Site1 8/1
Site2 8/2
Site3 8/3
Site4 8/5
Site2 8/6
Site2 8/7
Site3 8/8

As this list gets items added to it I want to populate a summary table on another sheet showing the dates each site was visited like this...

____8/1 8/2 8/3 8/4 8/5 8/6 8/7 8/8 8/9
Site1 X
Site2 -----X-------------X---X
Site3 -------X
Site4 --------------X

(Had to add dashes above to get the X's spaced out properly)

I'm competent with lookups and such but I imagine this needs an array formula or some index/match combination which I'm a little weak on.

The solution should also not require any updating as the source list is updated periodically.
