I tried to find the photographer, Kevin McElheran online. No luck, just more abandoned or broken links. I did find a description which was posted with another copy of the same photo, on two other sites. So, some background information about how the photo was taken. But, I still don't know what happened to <a href="https://twitter.com/kmcelheran">Kevin McElheran</a> from Calgary, Alberta.“This abandoned 100 year old church is what’s left from what was the rail town of Sorrento, British Columbia. I was driving through this area late one night when I noticed a train in the distance approaching which outlined this structure in it’s glow.”
I think the church is Notch Hill Church, not Saint Mary’s as the description says with the photo above. Notch Hill Church is in Sorrento, BC and it is located right at the train tracks. One sites says it is Tappen, BC.
One way or another, this seems to the the church photographed. It was being restored but the site stopped posting in 2014. In 2016 I read a report about building materials being stolen from the site. The project is on hold due to lack of funds to replace them. The photo below was taken before the renovations began.
