Why yes, yes it is. I'm a nerd for Book of Mormon geography, and this is my map of where it all went down.
While I won't say that it did or didn't happen in one region or another, I will say that this is my interpretation or layout of how it's described during the period from Alma-Helaman. I appreciate having a layout, so I can envision the movements of all the armies. Having it set out like this allows me to ponder some questions. Like in Alma 51, it says that the city of Nephihah was so strongly fortified that Amalickiah refused to go against it. Instead, he headed for the city of Moroni (bottom right), and then continued on to take Lehi, Morianton, Omner, and Mulek. (It doesn't mention here anything about Jershon or Antionum.) They were headed toward Bountiful, when they were repulsed by Teancum and his men, who were "great warriors". I gather that Teancum and his men were likely the best of the Nephite forces; their elite. So why were they kept up in the north-east corner, when the Lamanites would've likely come up from their lands, in the south (the land of Nephi)? Having a good sense of the layout of the land helps bring up questions like these. Good things worth pondering.
Another interesting thing is that the "narrow neck of land" took one and a half days for a Nephite to cross, from the east to the west seas (Alma 22:32). Was this on foot, or horseback? Something I'd surely like to know. (And now that I looked, I already need to make an adjustment to my map. Bountiful goes all the way from the east sea to the west sea, not just the north-east corner. Alma 22:33)
One can say that the geography got all messed up when Jesus was crucified. Cities were sunken, burned, raised up and down... so it might all be entirely different from what it was. But I really enjoy having something to imagine with. Hopefully someday soon it'll all be revealed. What a fun day for all that will be!
