While on my trip to Yellowstone and the Tetons I took a number of pictures of signs that made me smile and laugh. I will now start a series of those images. These images require no explanation so I will let them speak for themselves.

My oldest cousin Don passed away a couple of days ago, and as he served in the Air Force I created this image in remembrance of him.
Oh! I have slipped the surly bonds of Earth
And danced the skies on laughter-silvered wings;
Sunward I've climbed, and joined the tumbling mirth
Of sun-split clouds, — and done a hundred things
You have not dreamed of — wheeled and soared and swung
High in the sunlit silence. Hov'ring there,
I've chased the shouting wind along, and flung
My eager craft through footless halls of air. . . .
Up, up the long, delirious burning blue
I've topped the wind-swept heights with easy grace
Where never lark, or ever eagle flew —
And, while with silent, lifting mind I've trod
The high untrespassed sanctity of space,
Put out my hand, and touched the face of God.

The Grand Canyon of the Yellowstone is the first large canyon on the Yellowstone River located downstream from Lower Yellowstone Falls. The mineral stains mark the sites of hot springs and steam vents in the canyon walls. For thousands of years, upwardly percolating fluids have altered the chemistry of the rocks, turning them yellow, red, white, and pink.

Here is a picture of Upper Falls of the Yellowstone River and a geology lesson. A waterfall forms in a river channel where harder rocks meets softer rocks that erode more easily and quickly. Here, volcanic and hydrothermal activity have created this 109-foot Upper Falls. About 480,000 years ago, lava formed a layer of rock that resists erosion. The lava naturally cracks in a zig-zag pattern. Over time, hydrothermal springs rose through some of these cracks, altering and weakening the lava. The Yellowstone River flowed through the zig-zag cracks and eroded its river channel. Once the river reached the softer, hydrothermally-altered rock, erosion increased and created the Upper Falls.
