this is located as you leave the main park in Zion and head towards Bryce Canyon, lots of parking to view the area. Thanks Dave.

i was a bit worried I wouldn't get the description correct. I know that you and Jim know your geology. I wish I deserved the title, I'll leave that to you but thanks Jerry.

This is certainly an attention getter Jer, lots of people stopping and taking photos. Zion is a wonderful place to visit.

Stan, some of the pine trees are fairly large. I wouldn't think there would be enough moisture but they all looked very healthy.

I've really learned a lot about geology the last couple of years. I try and research all of the areas we visit.

This geographically widespread formation reaches a thickness of 2,200 feet in Zion NP and consists almost entirely of desert sand dunes and has two sets of lines forming the checkerboard pattern. The horizontal lines, called cross bedding, represent layers of wind-blown sand that built up into sand dunes. These dunes were then buried, and the sand grains glued together by calcite and iron oxide to form sandstone.
The vertical lines are less common. They are shallow cracks that result from stress and erosion on the rock surface and were caused by expansion, contraction and temperature changes. I think I have this fairly correct geology wise, but nonetheless, it is interesting to view if you are in the park and worth the time to view.
