Stacking wood

Can anyone tell me how many calories are burned in a hour of stacking wood? I am loading a wagon and pulling it 20-30 feet then stacking the wood (heavy freaking wood at that) up to 6' tall. I am not chopping it (I don't have the ability)-so I get to do the grunt work. I know it would be more exercise to carry all the wood to the pile but there is about 3 cords so far and at least that many to go- way to much to take a few pieces at a time.
