Is this a wall cloud?

I took this photo of a storm in St. Louis County, MN back in September. I biked to a great vantage point in my local area and took video and photo, this is the clearest shot I got and I was wondering if this was a wall cloud? (Personally I think it is, but I’m by no means a professional, or even an experienced hobbyist as I only got into severe weather last May)
