I have created a number of story maps. I'm currently practicing with Leaflet and open source tools. However, I enjoy testing out the ESRI templates for story maps as well. Above, you can click on the buttons to visit two of my favorite story map creations. (NOTE: The Angels Landing Story Map was created with basemaps from the State of Utah, they were hosted on a public server. The basemaps have since moved and I have not been able to update this map with the new location due to their new security settings, I will hopefully update in the future)
The Neon Museum Map is an example of the ESRI Map Tour application. The photos (or course!) are mine, and I customized the basemap to give it a bit more of a "vintage" feel. You can read more about the methods in the metadata if you are interested --or in my blog: here.
My Angels Landing story map is a special project and I was honored when ESRI asked me if it could be displayed in the online ESRI Story Map gallery as a good example of their "Map Journal" template. My map is found a number of ways (and why I usually make a direct link to it). It is in the Parks and Recreation section of the ESRI online gallery.
You can also get to my Angel's Landing Map by clicking on the photo above. Yes, it is my photo! I hate to say that (but people do ask).
While I'm here -- I might as well add some commentary about the Angels Landing Map. I made this map in May 2015. I had experience with ArcGIS Online and had setup a full ArcServer/AGOL enterprise system and was working as an Administrator of a private site for a Navy project. I was familiar with the organizational accounts but I wasn't as familiar with the free ArcGIS Online experience that anyone can access and sign up for. I wanted to see how easy it would be to create one without paid ESRI software and my Angels Landing Map is a result of that effort. I admit, I put it together rather quickly -- in one intense weekend. When I look at it now I sometimes see little typos or things I'd like to fix and may do that. The technology changes fast as well -- I think there are better ways to link to info now that don't require much customization of the free templates (Such as buttons vs. links). I had thought about doing a blog to explain how to do this. If this is something you would like help with, let me know!
I did make almost the entire story map without touching an ArcMap license (or any other paid software). I did use ArcMap once just to transform KML to a shapefile when I was creating the trail map but that's it. The rest is out of the box and free on ArcGIS.com
