When my wife and I bought our place, the previous owner left a LOT of logs near the back fence. They sat for nearly two years. I tried to split them with a maul and a couple good wedges, but the wood was so dense that the wedges would just pop out upon hitting. So... they continued sitting.
A few weeks ago, I finally rented a hydraulic splitter and my dad and I got it all split... only took about 3.5 hours. In this picture, we've got a majority of it split already, but there was still a bunch of logs behind us. In total, it was well over a Face Cord of wood (4' x 8' x 16").
I have to add, this brought back a lot of great memories for us. The house I grew up in had a wood burning furnace. My dad and I spent a lot of time in the woods, cutting and dragging logs of downed trees up to the house, and splitting them into useable size. We had a great time together.
Anyway... onto the wood identification.
A lot of the wood we split ended up REALLY wavy. It was harder than a bugger to split. Our splitter (38 ton, I think) took a bit to get through the log.
A majority of the logs were this wavy wood. Neither he nor I have any idea what it might be.
Thanks in advance for the help.
