Moss Road - back a few posts you made a statement that certainly does not hold true here. You said that popular & cottonwood were hardwood types. Wow - around here there are popular, birch, alder & quakeing aspen. These are ALL very soft wood trees around here. Now Cottonwood - it's not only soft - it's a rotten type of wood. It will only grow in valleys/draws where it can get lots of water. It's not uncommon to have gigantic limbs on a Cottonwood to rot and fall off the main tree. Cottonwood will not even make good firewood. It rots and turns to dust even before it gets a chance to dry.
The only type of hardwoods around here would be something a person would plant in their yard. Homesteaders would some times plant Black Locust. Pretty sure that's a hardwood.
