Michigan loggers in 1890

About 53 logs, about 10' about 16" diameter, about some species, estimate at 700 lbs per log = 37100 lbs or 18.5 tons.
An internet search shows that supposedly this is doable with 2 horses but there are lots of other search items that would put the limit at much less. I imagine the real trick would be to get it sliding from the dead start.

The photo is real; I've seen it often since I was a kid in the 50's. It's associated with the Michigan pine lumber industry of the late 1800's. I'm pretty sure the photo is 'brag" photo since it would be too top-heavy to actually move very far in the northern Michigan terrain.
