Painted Hills


Painted Hills, John Day Fossil Beds
Eastern Oregon, USA

What is it made of

Layers of hard claystones which include ancient soils (palesols) and lake beds. Recently the surface of the hills had weathered into softer clay. The claystones were formed by several geographic events in the past 33 million yrs. the volcanic activity of cascade mountains (some 100 miles west) deposited layers of cooled ash. The atmosphere with the help of the plants and animals oxidized the ash. Ground water feed’ed the varied minerals. And in due course today’s claybeds were formed (wow what an amount of structural and chemical changes would have happened !!!!)

 

Colors of the Painted Hills

Aluminum, Silicon, Iron, Magnesium, Manganese, Sodium, Calcium, Phosphorus, Titanium, Potassium, Oxygen, Hydrogen – All this above and some additional elements by a very special secret recipe forms the beautiful colors of this wonderful scenery. Depending on the amount of moisture and the light available , the shades keeps varying thru the day and all seasons.

 

How come there is not much of flora on the hill

Its a interesting to note that there is not much of flora on the painted hills. And the reason is more interesting  – The clay on the painted hills has a great ability to absorb water and swell. And most of the plant are not able to compete with the soil for water. And the once that do, u can see them in the crevices and gullies of the red hills (the yellow ones that blossoms during the spring are chaenactis and bee-plant.

American Southwest – Monument Valley


Three Mittens, Monument Valley Navajo Park
UT , USA

 

Monument Valley is not really a valley, but an upwarp of sedimentary rock that is at least 260 million years old, surrounded by sentinels that have yet to fully erode. The floor itself is more than a mile high, part of the 130,000 square-mile Colorado Plateau. Sandstone is easily eroded, and the wind, rain, cycles of frost and heat have been at work, cracking and chiseling the valley to its present form.

Grand Canyon – The Making


Toroweep, Grand Canyon National Park
AZ, USA

While the Colorado river accounts for the canyon’s depth, its width and formations are the work of even greater forces. Wind rushing thru the canyon erodes the limestone and sandstone- a few grains at a time. Rain pouring over the rim cuts deep side canyons on the softer rock. Perhaps the greatest canyon building force is snow or ice ! Water from the snow melt and the rain work its way into the cracks on the rocks. When frozen, expands, forcing the rocks away from the canyon walls.

Ancient Drawing Board

Lower Calf Creek Trail
Grand Staircase-Escalante National Monument
Utah, USA

It was an amazing experience just walking between mineral-streaked cliffs of Navajo Sandstone, beaver ponds and pre-historic rock art sites en route to the 126-foot-high Lower Calf Creek Falls. The total roundtrip distance to the falls is 5-1/2 miles. Though the summer sun was above and my (a little over a year old) son was on the backpack, the hike was pretty enjoyable with very little elevation change. Most of the trail is sandy & that slows the pace, at times !

The most interesting part of the hike were the wall paintings and the Indian granaries (zoom in & zoom out) and of course the jewel of the crown being the lower falls itself.

On an entirely different perspective, we travel so far, hike so long to get a peek into the lives of the Anasazi Indians. These petroglyph on the walls of the canyons does provide the glimpse. But you know what, in most of these trails you see a notice that there are messages that indicate a heavy penalty if you make new makings (or painting) on these canyon walls (of course !!!)

We do have the technology to make new painting on these walls, that could last more the existing ones. If we are not allowed to make new paintings today how would people, 800 – 1000 years from get a glimpse onto ours lives …… right :-)

Wrong !!! As technology grows, live changes and so is the medium. Who knows even the blog(s) like these -yeah the same one u r reading now ;-) could serve the purpose of providing the window to our lives, in future. Time’s Person of the year , 2006 clearly indicated the significance of the user generated content (if you already don’t know Times Person of the year 2006 is YOU) .

The count of blogs, as of writing this post, just on WordPress.com alone is 1,562,804 blogs with 53,197 new posts today. Even after dropping off the test blogs and the inactive ones, it is still quiet a number – the point is there is a good amount of user content getting generated every day on the Internet.

What would happen to these valuable user generated content, once the user is no more ?Even if someone decides to manage and maintain a users content after user’s time, On what basis would the user account details be shared with the family or friends ? May be the blog or the site could be graciously closed, but what if the users demise is not expected ? Would these become asserts of the individuate and hence be part of his Will ? How would we differentiate between the valuable and junk out of these content ?

So many things to ponder about ….

The Earth is Cooking


Yellowstone National Park, WY, USA

This national park sits on 2000° lake of molten lava, an underground pressure cooker of 50 miles long and 30 miles wide. For atleast a few million years, since magma burned a hole under ancient Wyoming’s bedrock, yellow stone periodically disgorged a small ocean of lava in eruptions hundreds of times worse than any volcanic eruptions on earth.

Today, the volcanic action, heats the rocks below the surface, and this in turn creates all manner of spectacle in thousands of steaming hot springs and hundreds of geysers, plus bubbling mud-pots and fumaroles.
