Mzak, the campground is called the Bowl amd Pitcher at Riverside State Park in Washington.
Tjwoody - I don't remember off the top of my head, seeing a brand name when I unpacked the box. I purchased it via Amazon . The half umbrella is readily found from many sources there. Just do a search. They range in color, pole type, lighted (or not), and expense. There are many mods people use to attach their half umbie.
I don't always use it. I have several canopy types for various trips. The half umbie is good for still weather light breeze days.
I am attaching a photo of my tried and true canopy. It's an EZ Up brand, (commercial) canopy. It has been thru some wicked weather - strong gusting wind and torrential rains and held up beautifully. It wasn't a cheap purchase but it is still holding up 15 years later... but I noted a couple weeks ago it was on need of user maintenance...I may have to retire it this year. If so, then might try out the less expensive Clam screen house which is receiving rave reviews from happy A-Framers.
