Back when it had leaves, we took a sample to Bordine's.  The tree-guy there identified it as a Cherry.  Never saw any fruit.  It might have flowered once, the first year we were here.

Even then, it was in rough shape.  I brought-down the lowest horizontal branch, which was obviously rotten, the first summer.  The branch was dropping bark and branchlets into the yard.  We hoped that removing the obviously-diseased branch and applying a fungicide would save the tree.  It did not.  The tree has been succumbing since, each year losing a higher branch.  This last summer it had only token leaves on the highest branches.  A month or two ago we noticed ear-type fungus growing on the trunk.  Clearly dead.

Didn't threaten the house, really (might have brushed the south-west corner, but that's all).  Did threaten the fence.  With the multiple trunks, I needed help to fell it.  Cutting through the south-pointing horizontal branch, outside the fence, was the obvious initial cut.  But I wanted come-along ropes to ensure the tree dropped where I wanted it to drop.  Adam and Liz were here and happy to help (Thank you!).  Nic stayed with Goobs, and away from chainsaws, while we felled the tree.

Now I have to decide what to do with the wood.  The easiest thing is to cut it into firewood.  But I have two 5-foot racks full of firewood already, and the idea of burning Cherry is repugnant.  You make furniture out of that stuff, you don't burn it.  I guess I try to rough-cut it with a chainsaw into planks.  Maybe split some into something resembling turning blanks for Dad.
