Reading it takes ten seconds: 52 dots, one per week. Solid teal is Orem's swim season; the hollow teal run before it (April 25 to May 16) is when to open; the hollow amber run after is when to close, with October 7 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
