Landscape 2014

I do like flowing water, either sharp or flowing. Nice shots. But it looks like one of the men forgot his trunks?

A few days ago we were back in Arizona so we visited Petrified Forest National Park again.

Great set Henry. I was visiting Grand Canyon
for day and still sorting my images. Hopefully
get a couple that are half as good.

Nice set Henry.
More shots from Jamaica.

Love the desert shots Henry, Great contrast with the sky, 2 and 3 for me.

Nice glowering sky Valery, set against the green ocean - lovely shots, 1 is my fav.

[sury]

I love the first one too Valery. The ominous sky contrasting seemingly pacifying
green waters is a great example of Nature and its manifestations.

Those shots are better than the first lot I think Henry, you can see the obvious effects of erosion in those and the scenery is even more dramatic, nice work.
I’ve been reading up on the Petrified Forest trying to get an idea about how it formed, it’s really old, a couple of hundred million years old, (late Triassic) the original wood has all been replaced by mineralization leaching from the sedimentary layers that covered the fallen trees, mostly from volcanic ash from what I can gather.
I also wanted to know what happened to the carbon during that process but the article I was reading didn’t say.
Apparently geologically there was a large scale upwelling of the land mass in that area which caused large cracks through the area where the conifer (extinct species) forests were, which in turn caused erosion that further caused the collapse of ledges with trees growing on them into the new streams and rivers, those were then covered by siltation.
And then later (much later) the ‘trees’ were re-uncovered by further erosion, by which time the wood had become rock.

Ps very pretty place Valery.

This second time there in the last month (went there also a few years ago) I noticed a road inside the park that I had somehow missed about a month ago. I turned onto it and drove for a few miles and found the Blue Mesa area. I don't know how I missed that before. Really cool area. Walked for an hour or so down into a valley in the badlands that had lots of petrified logs with a much more interesting background than the places we were at a few weeks before.

Thanks, good info. I had read much the same thing on the internet and also the park brochure and map that I received when I entered had a lot of good info. For other people, here is some more good info:

I can see the cracks in that grey clay stuff and that made me remember the article describing the very high expansion rate it has when wet.
It sure is an amazing place for scenic views though, and intriguing, I’m glad you showed us Henry.

This forum is evolutionary in so many ways. Entertaining, edifying, enlightening and last but not least enjoyable.

Really good stuff from Henry. I like the first picture (on this page) best, since it really conveys the depth of that place. These certainly are interesting landscapes and I hope I could visit something like that one day (need to put in my lotto ticket for this week)

Thanks for looking! Yes, the Petrified Forest National Park in Arizona is just one of many fantastic natural areas in the U.S., particularly the western U.S. Where are you? If you are interested in amazing natural scenery and you just have a chance to visit one area then I would suggest Utah and northern Arizona. Lots of national parks, national monuments (similar to national parks, but one step down on the hierarchy, but often just as spectacular), and state parks.

Yes, I am trying to evolve a bit over the years from Knuckle Dragger to fully enlightened Earth Angel. Not there yet.

Not quite in the same league as Henry's Arizona.... Sunset at Grand Canyon, Mather Point Lookout.
