You are invited to upload one or more of your landscape photos and, if you’d like, to accompany your image with some commentary: challenges you faced in making the image? your intent for the image? settings? post-processing decisions? why you did what you did? the place and time? or an aspect you’d like feedback on? And please feel free to ask questions of others who have posted images or to join the discussion. If you don’t feel like using words, that’s OK too—unaccompanied images (or unaccompanied words, for that matter) are also very much welcomed. As for the technicalities, the usual forum guidelines apply: files < 1 MB; image size <1000 px maximum dimension.

My first post on the revamped site! There were some great photos that got posted on the "WAIT" version of this week's thread--It'd be great if you could repost them here so we don't lose them.  

Now, in honor of the new platform, a sunrise:

I wonder if this is some kinda fossil mudstone where aquatic animals once lived

Kind of--it's something called "tafoni," or honeycomb weathering, here in a sandstone. I think the leading explanation is something like this: small differences in hardness or small irregularities can intensify erosion at certain points, which then can further erode as wetting and drying in the tidal cycle lets salt crystalize in the pores in the rock in the slightly more moist depressions, prying off more grains as the crystals grow. The growing depressions then provide protection for intertidal animals, which can further excavate the holes. Eventually the pockets can get big enough to trap sand grains, which act to abrade the pockets every time a wave hits. So aquatic life can be involved, but not necessarily as the primary cause. I suspect they're fairly evenly spaced because once a depression starts to form, the rim stays drier and erodes less. Definitely an interesting image!

Thanks for the explanation, Leslie. Your answer is more knowledgeable than I would have given. Again you're increasing my vocabulary. 🙂  I don't always know what I photograph only that subjects are visually interesting. "Tafoni" sounds like a kind of pasta.
