Heartland Model Distances

Knoxsville (Clinch River) to Nauvoo = 613 miles (direct), 645 miles (indirect).

Knoxsville to Nashville = 185 miles.

Nashville to Nauvoo = 460 miles.

Nashville to Cairo, Il (Little Egypt) = 168 miles

Mosiah’s 16 explorers travel from the city of Zarahemla to Lehi-Nephi in 40 days = 15 miles/day = 600 miles. (perfect mileage and pace)

Alma fled 8 days from the Waters of Mormon to the “Land of Helam” and 12 days from Helam to the “Land of Zarahemla”. Traveling from the city of Nephi to the city of Zarahemla could represent over 600 miles / 20 days = 30 miles/day. That would be an unrealistic pace on foot with their flocks and grain.

However, this daily mileage could be increased significantly if Alma’s group were 1. on horseback/wagons 2. travelled downriver on barges, and 3. were “fleeing” the armies of King Noah and not pacing themselves for a months-long migration. 4. generally younger and healthy.

Average Daily Mileage:

LDS handcart pioneer = 15.7 miles/day.

Appalachian Trail Thru-hiker = 2200 miles/5 months = 15 miles/day, (20-25 max daily miles)

Horse-Mounted Company = 30 miles/day

Alma traveling with flocks and grain suggests the refugees were utilized domesticated beasts of burden, carts and wagons. Therefore, it’s not out of the realm of possibility that Alma’s likely energetic group could have pushed near 2.5 mph for 12 hr/day for 8 days = 240 miles max range. Knoxville to Nashville is a very doable 185 miles (23 mil/day, 2.3 mph for 10 hours/day) 

Also, the Book of Mormon may be counting the distance from the Waters of Mormon only to the borders of the “land of Helam” (Mos 23:3), and not the city of Nephi itself to the city of Helam. (ie adjacent river valley). Also, Mormon reports that it was only 12 days from the city of Helam to the “Land of Zarahemla” and does not specify the city of Zarahemla itself (Mos 24:25). Nashville to the border of the Land of Zarahemla (Cairo, Il) would only be a leisurely 168 miles. (1.5 mph x 10 hours/day = 10.5 mil/day x 12 days).  

So, considering the text, we may save on total distance needed to traveled. And, while Alma’s numbers are tight, they are not an order of magnitude off reality. Also, the Limhi detachment running into the Ohio River instead of the Mississippi and mistakenly following the Ohio River up to Upstate New York (Land of Desolation) is a good fit.
