Trains... Choo Choo, not the dirty kind.

Sure, what else would a logging operation burn but wood for a steam boiler. Just like the coal trains burning coal. Using just the slash would provide plenty of fuel for the engine, cook house, and any other heat needs of the logging operation.

Interesting, these cross logs aren't whole trees, but sections of trunks. But the ones that show they are the end of the trunk show how much had to be cut before the trunk snapped off.
