Help Me ID this Tree

(This post is for Bort - my favorite tree guy...)

I was walking in the woods here around the Luck Cabin when I happened upon this big barked tree. What I noticed first was the unusual tree knot in the bark, at the bottom of the trunk. It looked like a big button that you could press, and open up a portal to another world - the kind with unicorns, glitter falling from the sky and tiny people... tinier than me... (see pic below.)The bark of this tree goes upward in large vertical caverns, creating deep shadows in the crevices. I don't know what kind of tree this is- and was wondering if anyone can help me identify the type of tree by looking at the bark? Each kind of tree has it's own thumbprint of bark, just like their individual shaped leaves... :)

Building the Bathroom Wall with Local Wood

Yay! The Luck Cabin now has a 98% finished wall for dividing the kitchen and bathroom - and because I used locally milled pine it only cost 40$ to build an entire wall. That is super affordable compared to the pain staking, time consuming and toxic sheet rock commonly put into homes now. There is something to be said for the rustic look and it's ease of construction and price - so much more tactile and warm to me. I likes it!

I have never built a wall before but noted the process as my carpenter friend Mark threw this wall up in less then 3 hours. Level 2x4 studs in first....
Some horizontal and well as the vertical ones go into place to hold the wall together, but i like it cause it made cool little box shapes - that I can use for hanging pictures, putting shelves into, a rock collection cubby... boxes are endless awesomeness.
Then I wanted wide planks to be nailed to the studs to match the 'decor' of the rest of the Luck Cabin...
Sweeeeeet!!! It's almost complete. I even have cold and HOT water running to my tub now, from the gravity fed spring. Time to go wash some undies!
