This is a nice example of one of the many ways that you can use StoryMaps. From the Kentucky Geological Survey, it's their 2019-2020 Annual Report.
The post begins with a message by State Geologist Bill Haneberg saying:
"...we at KGS decided to change the look and delivery of our annual report. Printing and mailing a 50-ish-page full-color report cost us thousands of dollars each year and tied us to a static and timeworn format. We mailed hundreds of copies of our annual report to people on our mailing list each year but rarely knew if they were read or not. So we decided to do things differently.
This year, like so many other things in our lives, the KGS annual report is online in a format that allows links to supporting files, interactive graphics, and videos. Everyone on our annual report mailing list will receive a postcard with a scannable QR code that will bring up the annual report on desktop and mobile devices..."
